1.3 Description

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

www.ti.com

The OMAP-L137 is a Low-power applications processor based on an ARM926EJ-S™ and a C674x™DSP core. It provides significantly lower power than other members of the TMS320C6000™ platform ofDSPs.

The OMAP-L137 enables OEMs and ODMs to quickly bring to market devices featuring robust operatingsystems support, rich user interfaces, and high processing performance life through the maximumflexibility of a fully integrated mixed processor solution.

The dual-core architecture of the OMAP-L137 provides benefits of both DSP and Reduced Instruction SetComputer (RISC) technologies, incorporating a high-performance TMS320C674x DSP core and anARM926EJ-S core.

The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions andprocesses 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor andmemory system can operate continuously.

The ARM core has a coprocessor 15 (CP15), protection module, and Data and program MemoryManagement Units (MMUs) with table look-aside buffers. It has separate 16K-byte instruction and16K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT). The ARM corealso has a 8KB RAM (Vector Table) and 64KB ROM.

The OMAP-L137 DSP core uses a two-level cache-based architecture. The Level 1 program cache (L1P)is a 32KB direct mapped cache and the Level 1 data cache (L1D) is a 32KB 2-way set-associative cache.The Level 2 program cache (L2P) consists of a 256KB memory space that is shared between programand data space. L2 also has a 1024KB ROM. L2 memory can be configured as mapped memory, cache,or combinations of the two. Although the DSP L2 is accessible by ARM and other hosts in the system, anadditional 128KB RAM shared memory is available for use by other hosts without affecting DSPperformance.

The peripheral set includes: a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output(MDIO) module; two inter-integrated circuit (I2C) Bus interfaces; 3 multichannel audio serial port (McASP)with 16/12/4 serializers and FIFO buffers; 2 64-bit general-purpose timers each configurable (oneconfigurable as watchdog); a configurable 16-bit host port interface (HPI); up to 8 banks of 16 pins ofgeneral-purpose input/output (GPIO) with programmable interrupt/event generation modes, multiplexedwith other peripherals; 3 UART interfaces (one with RTS and CTS); 3 enhanced high-resolution pulsewidth modulator (eHRPWM) peripherals; 3 32-bit enhanced capture (eCAP) module peripherals which canbe configured as 3 capture inputs or 3 auxiliary pulse width modulator (APWM) outputs; 2 32-bit enhancedquadrature pulse (eQEP) peripherals; and 2 external memory interfaces: an asynchronous and SDRAMexternal memory interface (EMIFA) for slower memories or peripherals, and a higher speed memoryinterface (EMIFB) for SDRAM.

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the OMAP-L137and the network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and100 Mbps in either half- or full-duplex mode. Additionally an Management Data Input/Output (MDIO)interface is available for PHY configuration.

The HPI, I2C, SPI, USB1.1 and USB2.0 ports allow the OMAP-L137 to easily control peripheral devicesand/or communicate with host processors.

The rich peripheral set provides the ability to control external peripheral devices and communicate withexternal processors. For details on each of the peripherals, see the related sections later in this documentand the associated peripheral reference guides.

The OMAP-L137 has a complete set of development tools for both the ARM and DSP. These include Ccompilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™debugger interface for visibility into source code execution.

•Separate instruction and data AHB bus interfaces•Embedded Trace Module and Embedded Trace Buffer (ETM/ETB)

For more complete details on the ARM9, refer to the ARM926EJ-S Technical Reference Manual, availableat http://www.arm.com

The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction anddata caches, Memory Management Unit (MMU), and other ARM subsystem functions. The CP15 registersare programmed using the MRC and MCR ARM instructions, when the ARM in a privileged mode such assupervisor or system mode.

A single set of two level page tables stored in main memory is used to control the address translation,permission checks and memory region attributes for both data and instruction accesses. The MMU uses asingle unified Translation Lookaside Buffer (TLB) to cache the information held in the page tables. TheMMU features are:•Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme.•Mapping sizes are:– 1MB (sections)

– 64KB (large pages)– 4KB (small pages)– 1KB (tiny pages)•Access permissions for large pages and small pages can be specified separately for each quarter ofthe page (subpage permissions)•Hardware page table walks•Invalidate entire TLB, using CP15 register 8•Invalidate TLB entry, selected by MVA, using CP15 register 8•Lockdown of TLB entries, using CP15 register 10

The size of the Instruction cache is 16KB, Data cache is 16KB. Additionally, the caches have the followingfeatures:

•Virtual index, virtual tag, and addressed using the Modified Virtual Address (MVA)•Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and withtwo dirty bits in the Dcache•Dcache supports write-through and write-back (or copy back) cache operation, selected by memoryregion using the C and B bits in the MMU translation tables•Critical-word first cache refilling•Cache lockdown registers enable control over which cache ways are used for allocation on a line fill,providing a mechanism for both lockdown, and controlling cache corruption•Dcache stores the Physical Address TAG (PA TAG) corresponding to each Dcache entry in the TAGRAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in theTAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing thepossibility of TLB misses related to the write-back address.•Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions ofthe Dcache or Icache, and regions of virtual memory.

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

The write buffer is used for all writes to a noncachable bufferable region, write-through region and writemisses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back forcache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and afour-address buffer. The Dcache write-back has eight data word entries and a single address entry.

The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the Config bus andthe external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by theConfig Bus and the external memories bus.

To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of anEmbedded Trace Macrocell (ETM). The ARM926ES-J Subsystem in the OMAP-L137 also includes theEmbedded Trace Buffer (ETB). The ETM consists of two parts:•Trace Port provides real-time trace capability for the ARM9.•Triggering facilities provide trigger resources, which include address and data comparators, counter,and sequencers.

The OMAP-L137 trace port is not pinned out and is instead only connected to the Embedded Trace Buffer.The ETB has a 4KB buffer memory. ETB enabled debug tools are required to read/interpret the capturedtrace data.

By default the ARM has access to most on and off chip memory areas, including the DSP Internalmemories, EMIFA, EMIFB, and the additional 128K byte on chip shared SRAM. Likewise almost all of theon chip peripherals are accessible to the ARM by default.

To improve security and/or robustness the OMAP-L137 has extensive memory and peripheral protectionunits which can be configured to limit access rights to the various on / off chip resources to specific hosts;including the ARM as well as other master peripherals. This allows the system tasks to be partitionedbetween the ARM and DSP as best suites the particular application; while enhancing the overallrobustness of the solution.

See Table 3-3 for a detailed top level OMAP-L137 memory map that includes the ARM memory space.

Values larger than 32 bits, such as 40-bit-long or 64-bit-long values arestored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or32 MSBs in the next upper register (which is always an odd-numbered register).

The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing oneinstruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L unitsperform a general set of arithmetic, logical, and branch functions. The .D units primarily load data frommemory to the register file and store results from the register file into memory.

The C674x CPU combines the performance of the C64x+ core with the floating-point capabilities of theC67x core.

Each C674x .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies withadd/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support forGalois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs andmodems require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputsand produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with roundingcapability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The32 x 32 bit multiply instructions provide the extended precision necessary for high-precision algorithms ona variety of signed and unsigned 32-bit data types.

The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on apair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit dataperforming dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.

The C674x core enhances the .S unit in several ways. On the previous cores, dual 16-bit MIN2 and MAX2comparisons were only available on the .L units. On the C674x core they are also available on the .S unitwhich increases the performance of algorithms that do searching and sorting. Finally, to increase datapacking and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bitand dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Packinstructions return parallel results to output precision including saturation support.

Other new features include:•SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops wheremultiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code sizeassociated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.•Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many commoninstructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C674xcompiler can restrict the code to use certain registers in the register file. This compression isperformed by the code generation tools.•Instruction Set Enhancement - As noted above, there are new instructions such as 32-bitmultiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois fieldmultiplication.

•Exceptions Handling - Intended to aid the programmer in isolating bugs. The C674x CPU is able todetect and respond to exceptions, both from internally detected sources (such as illegal op-codes) andfrom system events (such as a watchdog time expiration).•Privilege - Defines user and supervisor modes of operation, allowing the operating system to give abasic level of protection to sensitive resources. Local memory is divided into multiple pages, each withread, write, and execute permissions.

The DSP memory map is shown in Section 3.5 .

By default the DSP also has access to most on and off chip memory areas, with the exception of the ARMRAM, ROM, and AINTC interrupt controller. The DSP also boots first, and must release the ARM fromreset before the ARM can execute any code. This allows the DSP (the secure host) to configure thememory and IO protection and ensure security first, before the ARM can even attempt to access any ofthe device resources.

Additionally, the DSP megamodule includes the capability to limit access to its internal memories throughits SDMA port; without needing an external MPU unit.

The DSP does not have access to the ARM internal memory.

The DSP has access to the following External memories:•Asynchronous EMIF / SDRAM / NAND / NOR Flash (EMIFA)•SDRAM (EMIFB)

The DSP has access to the following DSP memories:•L2 RAM•L1P RAM•L1D RAM

The C674x core uses a two-level cache-based architecture. The Level 1 Program cache (L1P) is 32 KBdirect mapped cache and the Level 1 Data cache (L1D) is 32 KB 2-way set associated cache. The Level 2memory/cache (L2) consists of a 256 KB memory space that is shared between program and data space.L2 memory can be configured as mapped memory, cache, or a combination of both.

Table 3-2 shows a memory map of the C674x CPU cache registers for the device.

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

www.ti.com

The following system level features of the chip are controlled by the SYSCFG peripheral:•Readable Device, Die, and Chip Revision ID•Control of Pin Multiplexing•Priority of bus accesses different bus masters in the system•Capture at power on reset the chip BOOT[15:0] pin values and make them available to software•Special case settings for peripherals:– Locking of PLL controller settings– Default burst sizes for EDMA3 TC0 and TC1– Selection of the source for the eCAP module input capture (including on chip sources)– McASP AMUTEIN selection and clearing of AMUTE status for the three McASP peripherals– Control of the reference clock source and other side-band signals for both of the integrated USBPHYs

– Clock source selection for EMIFA and EMIFB•Source of emulation suspend signal (from either ARM or DSP) of peripherals supporting this function•Control of on-chip inter-processor interrupts for signaling between ARM and DSP

Since the SYSCFG peripheral controls global operation of the device, its registers are protected againsterroneous accesses by several mechanisms:•A special key sequence must be written to KICK0, KICK1 registers before any other registers arewriteable.

– Unlock sequence: write 0x83e70b13 to KICK0, then write 0x95A4F1E0 to KICK1– SYSCFG remains unlocked after the unlock sequence until locked again.– Any number of accesses may be performed while the module is unlocked– Locking the module is accomplished by writing any other value to either KICK0 or KICK1•Additionally, many registers are accessible only by a host ( ARM or DSP) when it is operating in itsprivileged mode. (ex. from the kernel, but not from user space code).

Device level pin multiplexing is controlled by registers PINMUX0 - PINMUX19 in the SYSCFG module.

For the OMAP-L13x device family, pin multiplexing can be controlled on a pin-by-pin basis. Each pin thatis multiplexed with several different functions has a corresponding 4-bit field in one of the PINMUXregisters.

Pin multiplexing selects which of several peripheral pin functions controls the pin's IO buffer output dataand output enable values only. The default pin multiplexing control for almost every pin is to select 'none'of the peripheral functions in which case the pin's IO buffer is held tri-stated.

Note that the input from each pin is always routed to all of the peripherals that share the pin; the PINMUXregisters have no effect on input from a pin. This feature allows a pin such asAHCLKX0/AHCLKX2/USB_REFCLKIN/GP2[11] to be used as both the McASP0 AHCLKX0 (output) pin,and the McASP2 AHCLKX2 master clock (output) pin simultaneously.

Section 4.2.1 through Section 4.2.20 contain the specific bit field definitions for the PINMUX registers onthe OMAP-L137 devices.

TI offers an extensive line of development tools for the OMAP-L13x platform, including tools to evaluatethe performance of the processors, generate code, develop algorithm implementations, and fully integrateand debug software and hardware modules. The tool's support documentation is electronically availablewithin the Code Composer Studio™ Integrated Development Environment (IDE).

The following products support development of OMAP-L13x applications:

Software Development Tools:Code Composer Studio™ Integrated Development Environment (IDE): including EditorC/C++/Assembly Code Generation, and Debug plus additional development toolsScalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time targetsoftware needed to support any application.

Hardware Development Tools:Extended Development System (XDS™) EmulatorFor a complete listing of development-support tools for OMAP-L13x, visit the Texas Instruments website on the Worldwide Web at http://www.ti.com uniform resource locator (URL). For information onpricing and availability, contact the nearest TI field sales office or authorized distributor.

To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of allDSP devices and support tools. Each DSP commercial family member has one of three prefixes: TMX,TMP, or TMS (e.g., TMS320C6745). Texas Instruments recommends two of three possible prefixdesignators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages ofproduct development from engineering prototypes (TMX/TMDX) through fully qualified productiondevices/tools (TMS/TMDS).

Device development evolutionary flow:

XExperimental device that is not necessarily representative of the final device's electricalspecifications.

PFinal silicon die that conforms to the device's electrical specifications but has not completedquality and reliability verification.

NULL Fully-qualified production device.

Support tool development evolutionary flow:

TMDX Development-support product that has not yet completed Texas Instruments internalqualification testing.

TMDS Fully qualified development-support product.

TMX and TMP devices and TMDX development-support tools are shipped against the followingdisclaimer:

"Developmental product is intended for internal evaluation purposes."

TMS devices and TMDS development-support tools have been characterized fully, and the quality andreliability of the device have been demonstrated fully. TI's standard warranty applies.

Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standardproduction devices. Texas Instruments recommends that these devices not be used in any productionsystem because their expected end-use failure rate still is undefined. Only qualified production devices areto be used.

A. The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and itstransmission line effects must be taken into account. A transmission line with a delay of 2 ns or longer can be used toproduce the desired transmission line effect. The transmission line is intended as a load only. It is not necessary toadd or subtract the transmission line delay (2 ns or longer) from the data sheet timings.Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at thedevice pin.

OMAP-L13x devices include on chip logic that ensures I/O pins are tri-stated during the power on ramp,as long as the RESET\ pin is asserted. This is true even if the core voltage (CVDD) has not yet ramped.

Normally, the only requirement during the power on ramp is that both the RESET\ and TRST\ pins remainasserted (low) until after the power supply rails have fully ramped.

However, if the on chip USB modules are used; then to limit any noise on the USB0_DM, USB0_DP,USB1_DM, and USB1_DP pins to less than 200mV during the power on ramp, the sequence illustrated inFigure 6-4 must be followed. The requirement is that the core supply (CVDD) must ramp to at least 0.9V(1) before the IO supply (DVDD) reaches the 1.65V point in its ramp (2). And as is always the case,RESET\ and TRST\ must remain asserted during the power on ramp and released only after CVDD andDVDD are within their specified ranges.

The OMAP-L137 has one PLL controller that provides clock to different parts of the system. PLL0 providesclocks (though various dividers) to most of the components of the device.

The PLL controller provides the following:•Glitch-Free Transitions (on changing clock settings)•Domain Clocks Alignment•Clock Gating•PLL power down

The various clock outputs given by the controller are as follows:•Domain Clocks: SYSCLK [1:n]•Auxiliary Clock from reference clock source: AUXCLK

Various dividers that can be used are as follows:•Post-PLL Divider: POSTDIV•SYSCLK Divider: D1, , Dn

Various other controls supported are as follows:•PLL Multiplier Control: PLLM•Software programmable PLL Bypass: PLLEN

The OMAP-L137 DSP generates the high-frequency internal clocks it requires through an on-chip PLL.

The PLL requires some external filtering components to reduce power supply noise as shown inFigure 6-7 .

Figure 6-7. PLL External Filtering Components

The input to the PLL is either from the on-chip oscillator (OSCIN pin) or from an external clock on theCLKIN pin. The PLL outputs nine clocks that have programmable divider options. Figure 6-8 illustrates thePLL Topology.

The PLL is disabled by default after a device reset. It must be configured by software according to theallowable operating conditions listed in Table 6-2 before enabling the DSP to run from the PLL by settingPLLEN = 1.

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

PLL0 is controlled by PLL Controller 0. The PLLC0 manages the clock ratios, alignment, and gating for thesystem clocks to the chip. The PLLC is responsible for controlling all modes of the PLL through software,in terms of pre-division of the clock inputs, multiply factor within the PLL, and post-division for each of thechip-level clocks from the PLL output. The PLLC also controls reset propagation through the chip, clockalignment, and test points.

PLLC0 generates several clocks from the PLL0 output clock for use by the various processors andmodules. These are summarized in Table 6-3 . The clock ratios between SYSCLK1, SYSCLK2, SYSCLK4and SYSCLK6 must always be maintained as shown in the table.

The ARM9 CPU core supports 2 direct interrupts: FIQ and IRQ. The ARM Interrupt Controller on theOMAP-L13x extends the number of interrupts to 100, and provides features like programmable masking,priority, hardware nesting support, and interrupt vector generation. The OMAP-L13x ARM Interruptcontroller is enhanced from previous devices like the DM6446 and DM355.

On OMAP-L13x, the ARM Interrupt controller organizes interrupts into the following hierarchy:•Peripheral Interrupt Requests– Individual Interrupt Sources from Peripherals•100 System Interrupts– One or more Peripheral Interrupt Requests are combined (fixed configuration) to generate aSystem Interrupt.– After prioritization, the AINTC will provide an interrupt vector based unique to each System Interrupt•32 Interrupt Channels– Each System Interrupt is mapped to one of the 32 Interrupt Channels– Channel Number determines the first level of prioritization, Channel 0 is highest priority and 31lowest.

– If more than one system interrupt is mapped to a channel, priority within the channel is determinedby system interrupt number (0 highest priority)•Host Interrupts (FIQ and IRQ)– Interrupt Channels 0 and 1 generate the ARM FIQ interrupt– Interrupt Channels 2 through 31 Generate the ARM IRQ interrupt•Debug Interrupts

– Two Debug Interrupts are supported and can be used to trigger events in the debug subsystem– Sources can be selected from any of the System Interrupts or Host Interrupts

The AINTC also generates an interrupt vector in hardware for both IRQ and FIQ host interrupts. This maybe used to accelerate interrupt dispatch. A unique vector is generated for each of the 100 systeminterrupts. The vector is computed in hardware as:VECTOR = BASE + (SYSTEM INTERRUPT NUMBER ×SIZE)

Where BASE and SIZE are programmable. The computed vector is a 32-bit address which maydispatched to using a single instruction of type LDR PC, [PC, #- < offset_12>] at the FIQ and IRQ vectorlocations (0xFFFF0018 and 0xFFFF001C respectively).

Interrupt nesting occurs when an interrupt service routine re-enables interrupts, to allow the CPU tointerrupt the ISR if a higher priority event occurs. The AINTC provides hardware support to facilitateinterrupt nesting. It supports both global and per host interrupt (FIQ and IRQ in this case) automaticnesting. If enabled, the AINTC will automatically update an internal nesting register that temporarily masksinterrupts at and below the priority of the current interrupt channel. Then if the ISR re-enables interrupts;only higher priority channels will be able to interrupt it. The nesting level is restored by the ISR by writingto the nesting level register on completion. Support for nesting can be enabled/disabled by software, withthe option of automatic nesting on a global or per host interrupt basis; or manual nesting.

6.8 General-Purpose Input/Output (GPIO)

6.8.1 GPIO Register Description(s)

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

www.ti.com

The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs.When configured as an output, a write to an internal register can control the state driven on the output pin.When configured as an input, the state of the input is detectable by reading the state of an internalregister. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in differentinterrupt/event generation modes. The GPIO peripheral provides generic connections to external devices.The GPIO pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of GPIO [0:15]).

The OMAP-L137 GPIO peripheral supports the following:•Up to 128 Pins on ZKB package configurable as GPIO•External Interrupt and DMA request Capability– Every GPIO pin may be configured to generate an interrupt request on detection of rising and/orfalling edges on the pin.– The interrupt requests within each bank are combined (logical or) to create eight unique bank levelinterrupt requests.– The bank level interrupt service routine may poll the INTSTATx register for its bank to determinewhich pin(s) have triggered the interrupt.– GPIO Banks 0, 1, 2, 3, 4, 5, 6, and 7 Interrupts assigned to ARM INTC Interrupt Requests 42, 43,44, 45, 46, 47, 48, and 49 respectively– GPIO Banks 0, 1, 2, 3, 4, 5, 6, and 7 Interrupts assigned to DSP Events 65, 41, 49, 52, 54, 59, 62and 72 respectively

– Additionally, GPIO Banks 0, 1, 2, 3, 4, and 5 Interrupts assigned to EDMA events 6, 7, 22, 23, 28,and 29 respectively.•Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIOsignal(s). This allows multiple firmware processes to toggle GPIO output signals without critical sectionprotection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching toanther process during GPIO programming).•Separate Input/Output registers•Output register in addition to set/clear so that, if preferred by firmware, some GPIO output signals canbe toggled by direct write to the output register(s).•Output register, when read, reflects output drive status. This, in addition to the input register reflectingpin status and open-drain I/O cell, allows wired logic be implemented.

The memory map for the GPIO registers is shown in Table 6-8 . See the OMAP-L137 ApplicationsProcessor DSP Peripherals Overview Reference Guide. – Literature Number SPRUGA6 for more details.

(1) On previous architectures, the EDMA3TC priority was controlled by the queue priority register (QUEPRI) in the EDMA3CCmemory-map. However for this device, the priority control for the transfer controllers is controlled by the chip-level registers in theSystem Configuration Module. You should use the chip-level registers and not QUEPRI to configure the TC priority.

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

EMIFA is one of two external memory interfaces supported on the OMAP-L137 . It is primarily intended tosupport asynchronous memory types, such as NAND and NOR flash and Asynchronous SRAM. Howeveron OMAP-L137 EMIFA also provides a secondary interface to SDRAM.

EMIFA supports asynchronous:•SRAM memories•NAND Flash memories•NOR Flash memories

The EMIFA data bus width is up to 16-bits on the ZKB package . The device supports up to fifteen addresslines and an external wait/interrupt input. Up to four asynchronous chip selects are supported by EMIFA(EMA_CS[5:2]) . All four chip selects are available on the ZKB package.

Each chip select has the following individually programmable attributes:•Data Bus Width•Read cycle timings: setup, hold, strobe•Write cycle timings: setup, hold, strobe•Bus turn around time•Extended Wait Option With Programmable Timeout•Select Strobe Option•NAND flash controller supports 1-bit and 4-bit ECC calculation on blocks of 512 bytes.

The OMAP-L137 ZKB package supports 16-bit SDRAM in addition to the asynchronous memories listed inSection 6.10.1 . It has a single SDRAM chip select (EMA_CS[0]). SDRAM configurations that aresupported are:•One, Two, and Four Bank SDRAM devices•Devices with Eight, Nine, Ten, and Eleven Column Address•CAS Latency of two or three clock cycles•Sixteen Bit Data Bus Width•3.3V LVCMOS Interface

Additionally, the SDRAM interface of EMIFA supports placing the SDRAM in Self Refresh and PowerdownModes. Self Refresh mode allows the SDRAM to be put into a low power state while still retaining memorycontents; since the SDRAM will continue to refresh itself even without clocks from the DSP. Powerdownmode achieves even lower power, except the DSP must periodically wake the SDRAM up and issuerefreshes if data retention is required.

Finally, note that the EMIFA does not support Mobile SDRAM devices.

Figure 6-11 illustrates an example of how SDRAM, NOR, and NAND flash devices might be connected toEMIFA of a OMAP-L137 device simultaneously. The SDRAM chip select must be EMA_CS[0]. Note thatthe NOR flash is connected to EMA_CS[2] and the NAND flash is connected to EMA_CS[3] in thisexample. Note that any type of asynchronous memory may be connected to EMA_CS[5:2].

The on-chip bootloader makes some assumptions on which chip select the contains the boot image, andthis depends on the boot mode. For NOR boot mode; the on-chip bootloader requires that the image bestored in NOR flash on EMA_CS[2]. For NAND boot mode, the bootloader requires that the boot image isstored in NAND flash on EMA_CS[3]. It is always possible to have the image span multiple chip selects,but this must be supported by second stage boot code stored in the external flash.

A likely use case with more than one EMIFA chip select used for NAND flash is illustrated in Figure 6-12 .This figure shows how two multiplane NAND flash devices with two chip selects each would connect to theEMIFA. In this case if NAND is the boot memory, then the boot image needs to be stored in the NANDarea selected by EMA_CS[3]. Part of the application image could spill over into the NAND regionsselected by other EMIFA chip selects; but would rely on the code stored in the EMA_CS[3] area tobootload it.

6.13 Ethernet Media Access Controller (EMAC)

6.13.1 EMAC Peripheral Register Description(s)

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

www.ti.com

The Ethernet Media Access Controller (EMAC) provides an efficient interface between OMAP-L137 andthe network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS) support.

The EMAC controls the flow of packet data from the OMAP-L137 device to the PHY. The MDIO modulecontrols PHY configuration and status monitoring.

Both the EMAC and the MDIO modules interface to the OMAP-L137 device through a custom interfacethat allows efficient data transmission and reception. This custom interface is referred to as the EMACcontrol module, and is considered integral to the EMAC/MDIO peripheral. The control module is also usedto multiplex and control interrupts.

6.14.2 Management Data Input/Output (MDIO) Electrical Data/Timing

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

www.ti.com

The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order toenumerate all PHY devices in the system.

The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface tointerrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIOmodule to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve thenegotiation results, and configure required parameters in the EMAC module for correct operation. Themodule is designed to allow almost transparent operation of the MDIO interface, with very littlemaintenance from the core processor. Only one PHY may be connected at any given time.

For more detailed information on the MDIO peripheral, see the OMAP-L137 Applications Processor DSPPeripherals Overview Reference Guide. – Literature Number SPRUGA6 .

For a list of supported MDIO registers see Table 6-35 [MDIO Registers].

6.15 Multichannel Audio Serial Ports (McASP0, McASP1, and McASP2)

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

www.ti.com

The McASP serial port is specifically designed for multichannel audio applications. Its key features are:•Flexible clock and frame sync generation logic and on-chip dividers•Up to sixteen transmit or receive data pins and serializers•Large number of serial data format options, including:– TDM Frames with 2 to 32 time slots per frame (periodic) or 1 slot per frame (burst)– Time slots of 8,12,16, 20, 24, 28, and 32 bits– First bit delay 0, 1, or 2 clocks– MSB or LSB first bit order– Left- or right-aligned data words within time slots•DIT Mode (optional) with 384-bit Channel Status and 384-bit User Data registers•Extensive error checking and mute generation logic•All unused pins GPIO-capable

Additionally, while the OMAP-L13x McASP modules are backward compatible with the McASP onprevious devices; the OMAP-L13x McASP includes the following new features:•Transmit & Receive FIFO Buffers for each McASP. Allows the McASP to operate at a higher samplerate by making it more tolerant to DMA latency.•Dynamic Adjustment of Clock Dividers– Clock Divider Value may be changed without resetting the McASP– A one-shot adjustment (+/-1 Input Clock) feature has been added to enable simple input/outputsample rate matching

The three McASPs on the OMAP-L137 are configured with the following options:

Figure 6-35 is a block diagram of the SPI module, which is a simple shift register and buffer plus controllogic. Data is written to the shift register before transmission occurs and is read from the buffer at the endof transmission. The SPI can operate either as a master, in which case, it initiates a transfer and drivesthe SPIx_CLK pin, or as a slave. Four clock phase and polarity options are supported as well as manydata formatting options.

Figure 6-35. Block Diagram of SPI Module

The SPI supports 3-, 4-, and 5-pin operation with three basic pins (SPIx_CLK, SPIx_SIMO, andSPIx_SOMI) and two optional pins ( SPIx_SCS, SPIx_ENA).

The optional SPIx_SCS (Slave Chip Select) pin is most useful to enable in slave mode when there areother slave devices on the same SPI port. The OMAP-L137 will only shift data and drive the SPIx_SOMIpin when SPIx_SCS is held low.

In slave mode, SPIx_ENA is an optional output and can be driven in either a push-pull or open-drainmanner. The SPIx_ENA output provides the status of the internal transmit buffer (SPIDAT0/1 registers). Infour-pin mode with the enable option, SPIx_ENA is asserted only when the transmit buffer is full, indicatingthat the slave is ready to begin another transfer. In five-pin mode, the SPIx_ENA is additionally qualifiedby SPIx_SCS being asserted. This allows a single handshake line to be shared by multiple slaves on thesame SPI bus.

In master mode, the SPIx_ENA pin is an optional input and the master can be configured to delay the startof the next transfer until the slave asserts SPIx_ENA. The addition of this handshake signal simplifies SPIcommunications and, on average, increases SPI bus throughput since the master does not need to delayeach transfer long enough to allow for the worst-case latency of the slave device. Instead, each transfercan begin as soon as both the master and slave have actually serviced the previous SPI transfer.

Table gives parameters for all four slave clocking modes.(4) SPI1_ENA is driven low after the transmission completes if the SPIINT0.ENABLE_HIGHZ bit is programmed to 0. Otherwise it istri-stated. If tri-stated, an external pullup resistor should be used to provide a valid level to the master. This option is useful when tyingseveral SPI slave devices to a single master.

6.17 ECAP Peripheral Registers Description(s)

OMAP-L137 Low-Power Applications Processor

SPRS563A – SEPTEMBER 2008 – REVISED OCTOBER 2008

www.ti.com

The OMAP-L137 device contains up to three enhanced capture (eCAP) modules. Figure 6-41 shows afunctional block diagram of a module. See the OMAP-L137 Applications Processor DSP PeripheralsOverview Reference Guide. – Literature Number SPRUGA6 for more details.

Uses for ECAP include:•Speed measurements of rotating machinery (e.g. toothed sprockets sensed via Hall sensors)•Elapsed time measurements between position sensor triggers•Period and duty cycle measurements of Pulse train signals•Decoding current or voltage amplitude derived from cuty cycle encoded current/voltage sensors

The ECAP module described in this specification includes the following features:•32 bit time base•4 event time-stamp registers (each 32 bits)•Edge polarity selection for up to 4 sequenced time-stamp capture events•Interrupt on either of the 4 events•Single shot capture of up to 4 event time-stamps•Continuous mode capture of time-stamps in a 4 deep circular buffer•Absolute time-stamp capture•Difference mode time-stamp capture•All the above resources are dedicated to a single input pin

The eCAP modules are clocked at the SYSCLK2 rate.

The clock enable bits (ECAP1/2/3/4ENCLK) in the PCLKCR1 register are used to turn off the eCAPmodules individually (for low power operation). Upon reset, ECAP1ENCLK, ECAP2ENCLK,ECAP3ENCLK, and ECAP4EN CLK are set to low, indicating that the peripheral clock is off.

(1) Maximum MEP step size is based on worst-case process, maximum temperature and maximum voltage. MEP step size will increasewith low voltage and high temperature and decrease with voltage and cold temperature.Applications that use the HRPWM feature should use MEP Scale Factor Optimizer (SFO) estimation software functions. See the TIsoftware libraries for details of using SFO function in end applications. SFO functions help to estimate the number of MEP steps perSYSCLKOUT period dynamically while the HRPWM is in operation.

Frame-to-frame timing is derived through the following parameters in the LCD (RASTER_TIMING_1)register:

•Vertical front porch (VFP)•Vertical sync pulse width (VSW)•Vertical back porch (VBP)•Lines per panel (LPP)

Line-to-line timing is derived through the following parameters in the LCD (RASTER_TIMING_0) register:•Horizontal front porch (HFP)•Horizontal sync pulse width (HSW)•Horizontal back porch (HBP)•Pixels per panel (PPL)

LCD_AC_ENB_CS timing is derived through the following parameter in the LCD (RASTER_TIMING_2)register:

•AC bias frequency (ACB)

The display format produced in raster mode is shown in Figure 6-54 . An entire frame is delivered one lineat a time. The first line delivered starts at data pixel (1, 1) and ends at data pixel (P, 1). The last linedelivered starts at data pixel (1, L) and ends at data pixel (P, L). The beginning of each new frame isdenoted by the activation of I/O signal LCD_VSYNC. The beginning of each new line is denoted by theactivation of I/O signal LCD_HSYNC.

Having two I2C modules on the OMAP-L137 simplifies system architecture, since one module may beused by the DSP to control local peripherals ICs (DACs, ADCs, etc.) while the other may be used tocommunicate with other controllers in a system or to implement a user interface. Figure 6-61 is blockdiagram of the OMAP-L137 I2C Module.

Each I2C port supports:•Compatible with Philips® I2C Specification Revision 2.1 (January 2000)•Fast Mode up to 400 Kbps (no fail-safe I/O buffers)•Noise Filter to Remove Noise 50 ns or less•Seven- and Ten-Bit Device Addressing Modes•Master (Transmit/Receive) and Slave (Transmit/Receive) Functionality•Events: DMA, Interrupt, or Polling•General-Purpose I/O Capability if not used as I2C

Figure 6-65. USB2.0 Integrated Transceiver Interface Timing

The Power and Sleep Controllers (PSC) are responsible for managing transitions of system power on/off,clock on/off, resets (device level and module level). It is used primarily to provide granular power controlfor on chip modules (peripherals and CPU). A PSC module consists of a Global PSC (GPSC) and a set ofLocal PSCs (LPSCs). The GPSC contains memory mapped registers, PSC interrupts, a state machine foreach peripheral/module it controls. An LPSC is associated with every module that is controlled by the PSCand provides clock and reset control.

The PSC includes the following features:•Provides a software interface to:– Control module clock enable/disable– Control module reset– Control CPU local reset•Supports IcePick emulation features: power, clock and reset

The SoC includes two PSC modules.

Each PSC module controls clock states for several on the on chip modules, controllers and interconnectcomponents. Table 6-101 and Table 6-102 lists the set of peripherals/modules that are controlled by thePSC, the power domain they are associated with, the LPSC assignment and the default (power-on reset)module states. See the device-specific data manual for the peripherals available on a given device. Themodule states and terminology are defined in Section 6.32.1.2 .

A power domain can only be in one of the two states: ON or OFF, defined as follows:•ON: power to the domain is on•OFF: power to the domain is off

In the SoC , for both PSC0 and PSC1, the Always ON domain, or PD0 power domain, is always in the ONstate when the chip is powered-on. This domain is not programmable to OFF state.•On PSC0 PD1/PD_DSP Domain: Controls the sleep state for DSP L1 and L2 Memories•On PSC1 PD1/PD_SHRAM Domain: Controls the sleep state for the 128K Shared RAM

The PSC defines several possible states for a module. This states are essentially a combination of themodule reset asserted or de-asserted and module clock on/enabled or off/disabled. The module states aredefined in Table 6-103 .

Table 6-103. Module States

Module State Module Reset Module Clock Module State Definition

Enable De-asserted On A module in the enable state has its module reset de-asserted and it has itsclock on. This is the normal operational state for a given moduleDisable De-asserted Off A module in the disabled state has its module reset de-asserted and it has itsmodule clock off. This state is typically used for disabling a module clock tosave power. The SoC is designed in full static CMOS, so when you stop amodule clock, it retains the module’s state. When the clock is restarted, themodule resumes operating from the stopping point.SyncReset Asserted On A module state in the SyncReset state has its module reset asserted and it hasits clock on. Generally, software is not expected to initiate this stateSwRstDisable Asserted Off A module in the SwResetDisable state has its module reset asserted and it hasits clock disabled. After initial power-on, several modules come up in theSwRstDisable state. Generally, software is not expected to initiate this stateAuto Sleep De-asserted Off A module in the Auto Sleep state also has its module reset de-asserted and itsmodule clock disabled, similar to the Disable state. However this is a specialstate, once a module is configured in this state by software, it can“automatically” transition to “Enable” state whenever there is an internalread/write request made to it, and after servicing the request it will“automatically” transition into the sleep state (with module reset re de-assertedand module clock disabled), without any software intervention. The transitionfrom sleep to enabled and back to sleep state has some cycle latencyassociated with it. It is not envisioned to use this mode when peripherals arefully operational and moving data.

Auto Wake De-asserted Off A module in the Auto Wake state also has its module reset de-asserted and itsmodule clock disabled, similar to the Disable state. However this is a specialstate, once a module is configured in this state by software, it will“automatically” transition to “Enable” state whenever there is an internalread/write request made to it, and will remain in the “Enabled” state from thenon (with module reset re de-asserted and module clock on), without anysoftware intervention. The transition from sleep to enabled state has somecycle latency associated with it. It is not envisioned to use this mode whenperipherals are fully operational and moving data.

The RTC provides a time reference to an application running on the device. The current date and time istracked in a set of counter registers that update once per second. The time can be represented in 12-houror 24-hour mode. The calendar and time registers are buffered during reads and writes so that updates donot interfere with the accuracy of the time and date.

Alarms are available to interrupt the CPU at a particular time, or at periodic time intervals, such as onceper minute or once per day. In addition, the RTC can interrupt the CPU every time the calendar and timeregisters are updated, or at programmable periodic intervals.

The real-time clock (RTC) provides the following features:•100-year calendar (xx00 to xx99)•Counts seconds, minutes, hours, day of the week, date, month, and year with leap year compensation•Binary-coded-decimal (BCD) representation of time, calendar, and alarm•12-hour clock mode (with AM and PM) or 24-hour clock mode•Alarm interrupt•Periodic interrupt•Single interrupt to the CPU•Supports external 32.768-kHz crystal or external clock source of the same frequency•Separate isolated power supply

The clock reference for the RTC is an external 32.768-kHz crystal or an external clock source of the samefrequency. The RTC also has a separate power supply that is isolated from the rest of the system. Whenthe CPU and other peripherals are without power, the RTC can remain powered to preserve the currenttime and calendar information.

The source for the RTC reference clock may be provided by a crystal or by an external clock source. TheRTC has an internal oscillator buffer to support direct operation with a crystal. The crystal is connectedbetween pins RTC_XI and RTC_XO. RTC_XI is the input to the on-chip oscillator and RTC_XO is theoutput from the oscillator back to the crystal.

An external 32.768-kHz clock source may be used instead of a crystal. In such a case, the clock source isconnected to RTC_XI, and RTC_XO is left unconnected.

If the RTC is not used, the RTC_XI pin should be held low and RTC_XO should be left unconnected.
