This processor provides significantly lower power than other members of the TMS320C6000™ platform of DSPs. The device enables OEMs and ODMs to quickly bring to market devices with the following features through the maximum flexibility of a fully integrated, mixed processor solution: • Robust operating systems • Rich user interfaces • High processor performance The dual-core architecture of the device provides benefits of both DSP and reduced instruction set computer (RISC) technologies, incorporating a high-performance TMS320C674x DSP core and an ARM926EJ-S core. The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously. The ARM9 core has a coprocessor 15 (CP15), protection module, and data and program memory management units (MMUs) with table look-aside buffers. The ARM9 core has separate 16-KB instruction and 16-KB data caches. Both are 4-way associative with virtual index virtual tag (VIVT). The ARM9 core also has a 8KB of RAM (Vector Table) and 64KB of ROM. The device DSP core uses a 2-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 32-KB 2-way, set-associative cache. The level 2 program cache (L2P) 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 combinations of the two. Although the DSP L2 is accessible by the ARM9 and other hosts in the system, an additional 128KB of RAM shared memory is available for use by other hosts without affecting DSP performance. For security-enabled devices, TI’s Basic Secure Boot lets users protect proprietary intellectual property and prevents external entities from modifying user-developed algorithms. By starting from a hardwarebased “root-of-trust”, the secure boot flow ensures a known good starting point for code execution. By default, the JTAG port is locked down to prevent emulation and debug attacks; however, it can be enabled during the secure boot process during application development. The boot modules are encrypted while sitting in external nonvolatile memory, such as flash or EEPROM, and are decrypted and authenticated when loaded during secure boot. This protects the users’ IP and lets them securely set up the system and begin device operation with known, trusted code. OMAP-L138 C6000™ DSP+ARM Processor Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 3 OMAP-L138 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 www.ti.com Basic Secure Boot uses either SHA-1 or SHA-256, and AES-128 for boot image validation. Basic Secure Boot also uses AES-128 for boot image encryption. The secure boot flow employs a multilayer encryption scheme which not only protects the boot process but offers the ability to securely upgrade boot and application software code. A 128-bit device-specific cipher key, known only to the device and generated using a NIST-800-22 certified random number generator, is used to protect user encryption keys. When an update is needed, the customer uses the encryption keys to create a new encrypted image. Then the device can acquire the image through an external interface, such as Ethernet, and overwrite the existing code. For more details on the supported security features or TI’s Basic Secure Boot, refer to the TMS320C674x/OMAP-L1x Processor Security User’s Guide (SPRUGQ9). The peripheral set includes: • A 10/100 Mb/s Ethernet media access controller (EMAC) with a management data input/output (MDIO) module • One USB2.0 OTG interface; one USB1.1 OHCI interface • Two I2C Bus interfaces • One multichannel audio serial port (McASP) with 16 serializers and FIFO buffers • Two multichannel buffered serial ports (McBSPs) with FIFO buffers • Two SPI interfaces with multiple chip selects • Four 64-bit general-purpose timers each configurable (one configurable as a watchdog) • A configurable 16-bit HPI • Up to 9 banks of 16 pins of general-purpose I/O (GPIO) with programmable interrupt and event generation modes, multiplexed with other peripherals • Three UART interfaces (each with RTS and CTS) • Two enhanced high-resolution pulse width modulator (eHRPWM) peripherals • Three 32-bit enhanced capture (eCAP) module peripherals which can be configured as 3 capture inputs or 3 APWM outputs • Two external memory interfaces: – An asynchronous and SDRAM external memory interface (EMIFA) for slower memories or peripherals – A higher speed DDR2/Mobile DDR controller The EMAC provides an efficient interface between the device and a network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbps and 100 Mbps in either half- or full-duplex mode. Additionally, an MDIO interface is available for PHY configuration. The EMAC supports both MII and RMII interfaces. The SATA controller provides a high-speed interface to mass data storage devices. The SATA controller supports both SATA I (1.5 Gbps) and SATA II (3.0 Gbps). The uPP provides a high-speed interface to many types of data converters, FPGAs, or other parallel devices. The uPP supports programmable data widths between 8- to 16-bits on both channels. Singledata rate and double-data rate transfers are supported as well as START, ENABLE, and WAIT signals to provide control for a variety of data converters. A video port interface (VPIF) is included providing a flexible video I/O port. The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each of the peripherals, see the related sections in this document and the associated peripheral reference guides. The device has a complete set of development tools for the ARM9 and DSP. These tools include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows® debugger interface for visibility into source code execution. 4 OMAP-L138 C6000™ DSP+ARM Processor Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 OMAP-L138 www.ti.com 1.4 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Functional Block Diagram Figure 1-1 shows the functional block diagram of the device.

Production processing does not necessarily include testing of all parameters. 2.2 Device Compatibility The ARM926EJ-S RISC CPU is compatible with other ARM9 CPUs from ARM Holdings plc. The C674x DSP core is code-compatible with the C6000™ DSP platform and supports features of both the C64x+ and C67x+ DSP families. 2.3 ARM Subsystem The ARM Subsystem includes the following features: • ARM926EJ-S RISC processor • ARMv5TEJ (32/16-bit) instruction set • Little endian • System Control Co-Processor 15 (CP15) • MMU • 16KB Instruction cache • 16KB Data cache • Write Buffer • Embedded Trace Module and Embedded Trace Buffer (ETM/ETB) • ARM Interrupt controller 2.3.1 ARM926EJ-S RISC CPU The ARM Subsystem integrates the ARM926EJ-S processor. The ARM926EJ-S processor is a member of ARM9 family of general-purpose microprocessors. This processor is targeted at multi-tasking applications where full memory management, high performance, low die size, and low power are all important. The ARM926EJ-S processor supports the 32-bit ARM and 16 bit THUMB instruction sets, enabling the user to trade off between high performance and high code density. Specifically, the ARM926EJ-S processor supports the ARMv5TEJ instruction set, which includes features for efficient execution of Java byte codes, providing Java performance similar to Just in Time (JIT) Java interpreter, but without associated code overhead. The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both hardware and software debug. The ARM926EJ-S processor has a Harvard architecture and provides a complete high performance subsystem, including: • ARM926EJ -S integer core • CP15 system control coprocessor • Memory Management Unit (MMU) Device Overview Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 11 OMAP-L138 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 • • • • • www.ti.com Separate instruction and data caches Write buffer Separate instruction and data (internal RAM) interfaces 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, available at http://www.arm.com 2.3.2 CP15 The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and data caches, Memory Management Unit (MMU), and other ARM subsystem functions. The CP15 registers are programmed using the MRC and MCR ARM instructions, when the ARM in a privileged mode such as supervisor or system mode. 2.3.3 MMU 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 a single unified Translation Lookaside Buffer (TLB) to cache the information held in the page tables. The MMU 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 of the 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 2.3.4 Caches and Write Buffer The size of the Instruction cache is 16KB, Data cache is 16KB. Additionally, the caches have the following features: • 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 with two dirty bits in the Dcache • Dcache supports write-through and write-back (or copy back) cache operation, selected by memory region 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 TAG RAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in the TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the possibility of TLB misses related to the write-back address. • Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of the Dcache or Icache, and regions of virtual memory. 12 Device Overview Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 OMAP-L138 www.ti.com SPRS586F – JUNE 2009 – REVISED AUGUST 2013 The write buffer is used for all writes to a noncachable bufferable region, write-through region and write misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a four-address buffer. The Dcache write-back has eight data word entries and a single address entry. 2.3.5 Advanced High-Performance Bus (AHB) The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the Config bus and the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by the Config Bus and the external memories bus. 2.3.6 Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB) To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an Embedded Trace Macrocell (ETM). The ARM926ES-J Subsystem in the device also includes the Embedded 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 device 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 captured trace data. 2.3.7 ARM Memory Mapping By default the ARM has access to most on and off chip memory areas, including the DSP Internal memories, EMIFA, DDR2, and the additional 128K byte on chip shared SRAM. Likewise almost all of the on chip peripherals are accessible to the ARM by default. To improve security and/or robustness, the device has extensive memory and peripheral protection units 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 partitioned between the ARM and DSP as best suites the particular application; while enhancing the overall robustness of the solution See Table 2-4 for a detailed top level device memory map that includes the ARM memory space. 2.4 DSP Subsystem The DSP Subsystem includes the following features: • C674x DSP CPU • 32KB L1 Program (L1P)/Cache (up to 32KB) • 32KB L1 Data (L1D)/Cache (up to 32KB) • 256KB Unified Mapped RAM/Cache (L2) • Boot ROM (cannot be used for application code) • Little endian Device Overview Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 13 OMAP-L138 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 www.ti.com 32K Bytes L1P RAM/ Cache 256K Bytes L2 RAM 256 256 256 Cache Control Memory Protect BOOT ROM 256 Cache Control Memory Protect L1P Bandwidth Mgmt L2 Bandwidth Mgmt 256 256 256 Instruction Fetch 256 Power Down Interrupt Controller C674x Fixed/Floating Point CPU IDMA Register File A Register File B 64 64 256 CFG Bandwidth Mgmt Memory Protect EMC L1D Cache Control 32 MDMA 8 x 32 64 Configuration Peripherals Bus SDMA 64 64 64 High Performance Switch Fabric 32K Bytes L1D RAM/ Cache Figure 2-1. C674x Megamodule Block Diagram 2.4.1 C674x DSP CPU Description The C674x Central Processing Unit (CPU) consists of eight functional units, two register files, and two data paths as shown in Figure 2-2. The two general-purpose register files (A and B) each contain 32 32bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit data, 40bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or 32 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 one instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from memory 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 the C67x+ core. 14 Device Overview Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 OMAP-L138 www.ti.com SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Each C674x .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x 32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four 16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support for Galois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and modems require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputs and produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The 32 x 32 bit multiply instructions provide the extended precision necessary for high-precision algorithms on a 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 a pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data performing 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 MAX2 comparisons were only available on the .L units. On the C674x core they are also available on the .S unit which increases the performance of algorithms that do searching and sorting. Finally, to increase data packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack instructions 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 where multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size associated 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 common instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C674x compiler can restrict the code to use certain registers in the register file. This compression is performed by the code generation tools. • Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field multiplication. • Exceptions Handling - Intended to aid the programmer in isolating bugs. The C674x CPU is able to detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and from system events (such as a watchdog time expiration). • Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with read, write, and execute permissions. • Time-Stamp Counter - Primarily targeted for Real-Time Operating System (RTOS) robustness, a freerunning time-stamp counter is implemented in the CPU which is not sensitive to system stalls.

By default the DSP also has access to most on and off chip memory areas, with the exception of the ARM RAM, ROM, and AINTC interrupt controller. Additionally, the DSP megamodule includes the capability to limit access to its internal memories through its SDMA port; without needing an external MPU unit. 2.4.2.1 ARM Internal Memories The DSP does not have access to the ARM internal memory. 2.4.2.2 External Memories The DSP has access to the following External memories: • Asynchronous EMIF / SDRAM / NAND / NOR Flash (EMIFA) • SDRAM (DDR2) 2.4.2.3 DSP Internal Memories The DSP has access to the following DSP memories: • L2 RAM • L1P RAM • L1D RAM 2.4.2.4 C674x CPU The C674x core uses a two-level cache-based architecture. The Level 1 Program cache (L1P) is 32 KB direct mapped cache and the Level 1 Data cache (L1D) is 32 KB 2-way set associated cache. The Level 2 memory/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 2-2 shows a memory map of the C674x CPU cache registers for the device. Table 2-2.

Pin Map (Quad D) 2.7 Pin Multiplexing Control Device level pin multiplexing is controlled by registers PINMUX0 - PINMUX19 in the SYSCFG module. For the device family, pin multiplexing can be controlled on a pin-by-pin basis. Each pin that is multiplexed with several different functions has a corresponding 4-bit field in one of the PINMUX registers. Pin multiplexing selects which of several peripheral pin functions controls the pin's IO buffer output data and 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 PINMUX registers have no effect on input from a pin. 30 Device Overview Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 OMAP-L138 www.ti.com 2.8 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Terminal Functions Table 2-5 to Table 2-31 identify the external signal names, the associated pin/ball numbers along with the mechanical package designator, the pin type (I, O, IO, OZ, or PWR), whether the pin/ball has any internal pullup/pulldown resistors, whether the pin/ball is configurable as an IO in GPIO mode, and a functional pin description. 2.8.1 Device Reset, NMI and JTAG Table 2-5.

GP8[0] is initially configured as a reserved function after reset and will not be in a predictable state. This signal will only be stable after the GPIO configuration for this pin has been completed. Users should carefully consider the system implications of this pin being in an unknown state after reset.

All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different types (ie., input versus output), the table reflects the pin function direction for that particular peripheral. IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the device is out of reset. During reset, all of the pins associated with these registers are pulled down. If the application requires a pull-up, an external pull-up can be used. For electrical specifications on the pull-up and and internal pull-down circuits, see the Device Operating Conditions section. This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power supply DVDD3318_C.

Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the signal name highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different types (ie., input versus output), the table reflects the pin function direction for that particular peripheral. IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the device is out of reset. During reset, all of the pins associated with these registers are pulled down. If the application requires a pull-up, an external pull-up can be used. For electrical specifications on the pull-up and and internal pull-down circuits, see the Device Operating Conditions section. This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power supply DVDD3318_C.

This device does not support dedicated hardware boot modes; therefore, all boot modes utilize the internal ARM ROM. The input states of the BOOT pins are sampled and latched into the BOOTCFG register, which is part of the system configuration (SYSCFG) module, when device reset is deasserted. Boot mode selection is determined by the values of the BOOT pins. See Using the OMAP-L132/L138 Bootloader Application Report (SPRAB41) for more details on the ROM Boot Loader. The following boot modes are supported: • NAND Flash boot – 8-bit NAND – 16-bit NAND (supported on ROM revisions after d800k002 -- see the bootloader documents mentioned above to determine the ROM revision) • NOR Flash boot – NOR Direct boot (8-bit or 16-bit) – NOR Legacy boot (8-bit or 16-bit) – NOR AIS boot (8-bit or 16-bit) • HPI Boot • I2C0/I2C1 Boot – EEPROM (Master Mode) – External Host (Slave Mode) • SPI0/SPI1 Boot – Serial Flash (Master Mode) – SERIAL EEPROM (Master Mode) – External Host (Slave Mode) • UART0/UART1/UART2 Boot – External Host • MMC/SD0 Boot 3.2 SYSCFG Module 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 pin values and make them available to software • Control of the DeepSleep power management function • Enable and selection of the programmable pin pullups and pulldowns 74 Device Configuration Copyright © 2009–2013, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: OMAP-L138 OMAP-L138 www.ti.com • • • SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Special case settings for peripherals: – Locking of PLL controller settings – Default burst sizes for EDMA3 transfer controllers – Selection of the source for the eCAP module input capture (including on chip sources) – McASP AMUTEIN selection and clearing of AMUTE status for the McASP – Control of the reference clock source and other side-band signals for both of the integrated USB PHYs – Clock source selection for EMIFA – DDR2 Controller PHY settings – SATA PHY power management controls Selects the source of emulation suspend signal (from either ARM or DSP) of peripherals supporting this function.

This may be achieved via pullup/pulldown resistors. The device features internal pullup (IPU) and internal pulldown (IPD) resistors on most pins to eliminate the need, unless otherwise noted, for external pullup/pulldown resistors. An external pullup/pulldown resistor needs to be used in the following situations: • Boot and Configuration Pins: If the pin is both routed out and 3-stated (not driven), an external pullup/pulldown resistor is strongly recommended, even if the IPU/IPD matches the desired value/state. • Other Input Pins: If the IPU/IPD does not match the desired value/state, use an external pullup/pulldown resistor to pull the signal to the opposite rail. For the boot and configuration pins, if they are both routed out and 3-stated (not driven), it is strongly recommended that an external pullup/pulldown resistor be implemented. Although, internal pullup/pulldown resistors exist on these pins and they may match the desired configuration value, providing external connectivity can help ensure that valid logic levels are latched on these device boot and configuration pins. In addition, applying external pullup/pulldown resistors on the boot and configuration pins adds convenience to the user in debugging and flexibility in switching operating modes. Tips for choosing an external pullup/pulldown resistor: • Consider the total amount of current that may pass through the pullup or pulldown resistor. Make sure to include the leakage currents of all the devices connected to the net, as well as any internal pullup or pulldown resistors. • Decide a target value for the net. For a pulldown resistor, this should be below the lowest VIL level of all inputs connected to the net. For a pullup resistor, this should be above the highest VIH level of all inputs on the net. A reasonable choice would be to target the VOL or VOH levels for the logic family of the limiting device; which, by definition, have margin to the VIL and VIH levels. • Select a pullup/pulldown resistor with the largest possible value; but, which can still ensure that the net will reach the target pulled value when maximum current from all devices on the net is flowing through the resistor. The current to be considered includes leakage current plus, any other internal and external pullup/pulldown resistors on the net. • For bidirectional nets, there is an additional consideration which sets a lower limit on the resistance value of the external resistor. Verify that the resistance is small enough that the weakest output buffer can drive the net to the opposite logic level (including margin). • Remember to include tolerances when selecting the resistor value. • For pullup resistors, also remember to include tolerances on the IO supply rail. • For most systems, a 1-kΩ resistor can be used to oppose the IPU/IPD while meeting the above criteria. Users should confirm this resistor value is correct for their specific application. • For most systems, a 20-kΩ resistor can be used to compliment the IPU/IPD on the boot and configuration pins while meeting the above criteria. Users should confirm this resistor value is correct for their specific application. • For more detailed information on input current (II), and the low-/high-level input voltages (VIL and VIH) for the device, see Section 4.2, Recommended Operating Conditions. • For the internal pullup/pulldown resistors for all device pins, see the peripheral/system-specific terminal functions table.

RTC (RTC_CVDD) may be powered from an external device (such as a battery) prior to all other supplies being applied or powered-up at the same time as CVDD. If the RTC is not used, RTC_CVDD should be connected to CVDD. RTC_CVDD should not be left unpowered while CVDD is powered. 2. Core logic supplies: (a) All variable 1.3V - 1.0V core logic supplies (CVDD) (b) All static core logic supplies (RVDD, PLL0_VDDA, PLL1_VDDA, USB_CVDD, SATA_VDD). If voltage scaling is not used on the device, groups 2a) and 2b) can be controlled from the same power supply and powered up together. 3. All static 1.8V IO supplies (DVDD18, DDR_DVDD18, USB0_VDDA18, USB1_VDDA18 and SATA_VDDR) and any of the LVCMOS IO supply groups used at 1.8V nominal (DVDD3318_A, DVDD3318_B, or DVDD3318_C). 4. All analog 3.3V PHY supplies (USB0_VDDA33 and USB1_VDDA33; these are not required if both USB0 and USB1 are not used) and any of the LVCMOS IO supply groups used at 3.3V nominal (DVDD3318_A, DVDD3318_B, or DVDD3318_C). There is no specific required voltage ramp rate for any of the supplies as long as the LVCMOS supplies operated at 3.3V (DVDD3318_A, DVDD3318_B, or DVDD3318_C) never exceed the STATIC 1.8V supplies by more than 2 volts. RESET must be maintained active until all power supplies have reached their nominal values. 5.3.2 Power-Off Sequence The power supplies can be powered-off in any order as long as LVCMOS supplies operated at 3.3V (DVDD3318_A, DVDD3318_B, or DVDD3318_C) never exceed static 1.8V supplies by more than 2 volts.

Power-On Reset is initiated by bringing RESET and TRST low at the same time. POR sets all of the device internal logic to its default state. All pins are tri-stated with the exception of RESETOUT which remains active through the reset sequence, and RTCK/GP8[0]. If an emulator is driving TCK into the device during reset, then RTCK/GP8[0] will drive out RTCK. If TCK is not being driven into the device during reset, then RTCK/GP8[0] will drive low. RESETOUT in an output for use by other controllers in the system that indicates the device is currently in reset. While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for the device to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG port interface and device's emulation logic in the reset state. TRST only needs to be released when it is necessary to use a JTAG controller to debug the device or exercise the device's boundary scan functionality. Note: TRST is synchronous and must be clocked by TCK; otherwise, the boundary scan logic may not respond as expected after TRST is asserted. RESET must be released only in order for boundary-scan JTAG to read the variant field of IDCODE correctly. Other boundary-scan instructions work correctly independent of current state of RESET. For maximum reliability, the device includes an internal pulldown on the TRST pin to ensure that TRST will always be asserted upon power up and the device's internal emulation logic will always be properly initialized. JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG controllers may not drive TRST high but expect the use of a pullup resistor on TRST.

A software sequence is required to reset the RTC CAUTION: A watchdog reset triggers a POR. 5.4.2 Warm Reset A warm reset provides a limited reset to the device. Warm Reset is initiated by bringing only RESET low (TRST is maintained high through a warm reset). Warm reset sets certain portions of the device to their default state while leaving others unaltered. All pins are tri-stated with the exception of RESETOUT which remains active through the reset sequence, and RTCK/GP8[0]. If an emulator is driving TCK into the device during reset, then RTCK/GP8[0] will drive out RTCK. If TCK is not being driven into the device during reset, then RTCK/GP8[0] will drive low. RESETOUT is an output for use by other controllers in the system that indicates the device is currently in reset. During an emulation, the emulator will maintain TRST high and hence only warm reset (not POR) is available during emulation debug and development. RTCK/GP8[0] is maintained active through a warm reset.

These options are illustrated in Figure 5-6 and Figure 5-7. For input clock frequencies between 12 and 20 MHz, a crystal with 80 ohm max ESR is recommended. For input clock frequencies between 20 and 30 MHz, a crystal with 60 ohm max ESR is recommended. Typical load capacitance values are 10-20 pF, where the load capacitance is the series combination of C1 and C2. The CLKMODE bit in the PLLCTL register must be 0 to use the on-chip oscillator. If CLKMODE is set to 1, the internal oscillator is disabled. Figure 5-6 illustrates the option that uses on-chip 1.2V oscillator with external crystal circuit.

Clock PLLs The device has two PLL controllers that provide clocks to different parts of the system. PLL0 provides clocks (though various dividers) to most of the components of the device. PLL1 provides clocks to the DDR2/mDDR Controller and provides an alternate clock source for the ASYNC3 clock domain. This allows the peripherals on the ASYNC3 clock domain to be immune to frequency scaling operation on PLL0. 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, ¼, Dn Various other controls supported are as follows: • PLL Multiplier Control: PLLM • Software programmable PLL Bypass: PLLEN 90 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Links: OMAP-L138 Copyright © 2009–2013, Texas Instruments Incorporated OMAP-L138 www.ti.com 5.6.1 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 PLL Device-Specific Information The device 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 in Figure 58. 1.14V - 1.32V PLL0_VDDA 50R 0.1 µF 0.01 µF VSS 50R PLL0_VSSA 1.14V - 1.32V 50R PLL1_VDDA 0.1 µF VSS 50R 0.01 µF PLL1_VSSA Ferrite Bead: Murata BLM31PG500SN1L or Equivalent Figure 5-8. PLL External Filtering Components The external filtering components shown above provide noise immunity for the PLLs. PLL0_VDDA and PLL1_VDDA should not be connected together to provide noise immunity between the two PLLs. Likewise, PLL0_VSSA and PLL1_VSSA should not be connected together. The input to the PLL is either from the on-chip oscillator or from an external clock on the OSCIN pin. PLL0 outputs seven clocks that have programmable divider options. PLL1 outputs three clocks that have programmable divider options. Figure 5-9 illustrates the high-level view of the PLL Topology. The PLLs are disabled by default after a device reset. They must be configured by software according to the allowable operating conditions listed in Table 5-4 before enabling the device to run from the PLL by setting PLLEN = 1.

PLLC0 and PLLC1 manage the clock ratios, alignment, and gating for the system clocks to the chip. The PLLCs are responsible for controlling all modes of the PLL through software, in terms of pre-division of the clock inputs (PLLC0 only), multiply factors within the PLLs, and post-division for each of the chip-level clocks from the PLLs outputs. PLLC0 also controls reset propagation through the chip, clock alignment, and test points. PLLC0 provides clocks for the majority of the system but PLLC1 provides clocks to the DDR2/mDDR Controller and the ASYNC3 clock domain to provide frequency scaling immunity to a defined set or peripherals. The ASYNC3 clock domain can either derive its clock from PLL1_SYSCLK2 (for frequency scaling immunity from PLL0) or from PLL0_SYSCLK2 (for synchronous timing with PLL0) depending on the application requirements. In addition, some peripherals have specific clock options independent of the ASYNC clock domain. 5.6.3 Dynamic Voltage and Frequency Scaling (DVFS) The processor supports multiple operating points by scaling voltage and frequency to minimize power consumption for a given level of processor performance. Frequency scaling is achieved by modifying the setting of the PLL controllers’ multipliers, post-dividers (POSTDIV), and system clock dividers (SYSCLKn). Modification of the POSTDIV and SYSCLK values does not require relocking the PLL and provides lower latency to switch between operating points, but at the expense of the frequencies being limited by the integer divide values (only the divide values are altered the PLL multiplier is left unmodified). Non integer divide frequency values can be achieved by changing both the multiplier and the divide values, but when the PLL multiplier is changed the PLL must relock, incurring additional latency to change between operating points. Detailed information on modifying the PLL Controller settings can be found in the OMAP-L138 C6-Integra DSP+ARM Technical Reference Manual (SPRUH77).

The processor may communicate with the regulator using GPIOs, I2C or some other interface. When switching between voltage-frequency operating points, the voltage must always support the desired frequency. When moving from a high-performance operating point to a lower performance operating point, the frequency should be lowered first followed by the voltage. When moving from a low-performance operating point to a higher performance operating point, the voltage should be raised first followed by the frequency. Voltage operating points refer to the CVdd voltage at that point. Other static supplies must be maintained at their nominal voltages at all operating points. The maximum voltage slew rate for CVdd supply changes is 1 mV/us. For additional information on power management solutions from TI for this processor, follow the Power Management link in the Product Folder on www.ti.com for this processor. The processor supports multiple clock domains some of which have clock ratio requirements to each other. SYSCLK1:SYSCLK2:SYSCLK4:SYSCLK6 are synchronous to each other and the SYSCLKn dividers must always be configured such that the ratio between these domains is 1:2:4:1. The ASYNC and ASYNC3 clock domains are asynchronous to the other clock domains and have no specific ratio requirement.

The Power Manager controls changing operating points (both frequency and voltage) and handles the related tasks involved such as informing/controlling peripherals to provide graceful transitions between operating points. The Power Manager is bundled as a component of DSP/BIOS. 94 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Links: OMAP-L138 Copyright © 2009–2013, Texas Instruments Incorporated OMAP-L138 www.ti.com 5.7 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Interrupts The device has a large number of interrupts to service the needs of its many peripherals and subsystems. Both the ARM and C674x CPUs are capable of servicing these interrupts equally. The interrupts can be selectively enabled or disabled in either of the controllers. Also, the ARM and DSP can communicate with each other through interrupts controlled by registers in the SYSCFG module. 5.7.1 ARM CPU Interrupts The ARM9 CPU core supports two direct interrupts: FIQ and IRQ. The ARM Interrupt Controller (AINTC) extends the number of interrupts to 100, and provides features like programmable masking, priority, hardware nesting support, and interrupt vector generation. 5.7.1.1 ARM Interrupt Controller (AINTC) Interrupt Signal Hierarchy The ARM Interrupt controller organizes interrupts into the following hierarchy: • Peripheral Interrupt Requests – Individual Interrupt Sources from Peripherals • 101 System Interrupts – One or more Peripheral Interrupt Requests are combined (fixed configuration) to generate a System 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 31 lowest. – If more than one system interrupt is mapped to a channel, priority within the channel is determined by 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 5.7.1.2 AINTC Hardware Vector Generation The AINTC also generates an interrupt vector in hardware for both IRQ and FIQ host interrupts. This may be used to accelerate interrupt dispatch. A unique vector is generated for each of the 100 system interrupts. 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 may dispatched to using a single instruction of type LDR PC, [PC, #-] at the FIQ and IRQ vector locations (0xFFFF0018 and 0xFFFF001C respectively).

The AINTC provides hardware support to facilitate interrupt nesting. It supports both global and per host interrupt (FIQ and IRQ in this case) automatic nesting. If enabled, the AINTC will automatically update an internal nesting register that temporarily masks interrupts 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 writing to the nesting level register on completion. Support for nesting can be enabled/disabled by software, with the option of automatic nesting on a global or per host interrupt basis; or manual nesting. 5.7.1.4 AINTC System Interrupt Assignments Table 5-6.

It is used primarily to provide granular power control for on chip modules (peripherals and CPU). A PSC module consists of a Global PSC (GPSC) and a set of Local PSCs (LPSCs). The GPSC contains memory mapped registers, PSC interrupts, a state machine for each peripheral/module it controls. An LPSC is associated with every module that is controlled by the PSC and 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 PSC0 controls 16 local PSCs. PSC1 controls 32 local PSCs. Table 5-10.

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 5.8.1.2 Module States The PSC defines several possible states for a module. This states are essentially a combination of the module reset asserted or de-asserted and module clock on/enabled or off/disabled. The module states are defined in Table 5-13. Table 5-13. 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 its clock on. This is the normal operational state for a given module Disable De-asserted Off A module in the disabled state has its module reset de-asserted and it has its module clock off. This state is typically used for disabling a module clock to save power. The device is designed in full static CMOS, so when you stop a module clock, it retains the module’s state. When the clock is restarted, the module resumes operating from the stopping point. SyncReset Asserted On A module state in the SyncReset state has its module reset asserted and it has its clock on. Generally, software is not expected to initiate this state SwRstDisable Asserted Off A module in the SwResetDisable state has its module reset asserted and it has its clock disabled. After initial power-on, several modules come up in the SwRstDisable state. Generally, software is not expected to initiate this state Auto Sleep De-asserted Off A module in the Auto Sleep state also has its module reset de-asserted and its module clock disabled, similar to the Disable state. However this is a special state, once a module is configured in this state by software, it can “automatically” transition to “Enable” state whenever there is an internal read/write request made to it, and after servicing the request it will “automatically” transition into the sleep state (with module reset re de-asserted and module clock disabled), without any software intervention. The transition from sleep to enabled and back to sleep state has some cycle latency associated with it. It is not envisioned to use this mode when peripherals are fully operational and moving data. Auto Wake De-asserted Off A module in the Auto Wake state also has its module reset de-asserted and its module clock disabled, similar to the Disable state. However this is a special state, once a module is configured in this state by software, it will “automatically” transition to “Enable” state whenever there is an internal read/write request made to it, and will remain in the “Enabled” state from then on (with module reset re de-asserted and module clock on), without any software intervention. The transition from sleep to enabled state has some cycle latency associated with it. It is not envisioned to use this mode when peripherals are fully operational and moving data.

It is primarily intended to support asynchronous memory types, such as NAND and NOR flash and Asynchronous SRAM. However on this device, EMIFA also provides a secondary interface to SDRAM. 5.10.1 EMIFA Asynchronous Memory Support EMIFA supports asynchronous: • SRAM memories • NAND Flash memories • NOR Flash memories The EMIFA data bus width is up to 16-bits.The device supports up to 23 address lines and two external wait/interrupt inputs. Up to four asynchronous chip selects are supported by EMIFA (EMA_CS[5:2]). 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. 5.10.2 EMIFA Synchronous DRAM Memory Support The device supports 16-bit SDRAM in addition to the asynchronous memories listed in Section 5.10.1. It has a single SDRAM chip select (EMA_CS[0]). SDRAM configurations that are supported 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 Additionally, the SDRAM interface of EMIFA supports placing the SDRAM in Self Refresh and Powerdown Modes. Self Refresh mode allows the SDRAM to be put into a low power state while still retaining memory contents; since the SDRAM will continue to refresh itself even without clocks from the device. Powerdown mode achieves even lower power, except the device must periodically wake the SDRAM up and issue refreshes if data retention is required. Finally, note that the EMIFA does not support Mobile SDRAM devices. Table 5-19 shows the supported SDRAM configurations for EMIFA. 116 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Links: OMAP-L138 Copyright © 2009–2013, Texas Instruments Incorporated OMAP-L138 www.ti.com SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Table 5-19.

Additional loads will limit the SDRAM operation to lower speeds and the maximum speed should be confirmed by board simulation using IBIS models. 5.10.4 EMIFA Connection Examples Figure 5-10 illustrates an example of how SDRAM, NOR, and NAND flash devices might be connected to EMIFA simultaneously. The SDRAM chip select must be EMA_CS[0]. Note that the NOR flash is connected to EMA_CS[2] and the NAND flash is connected to EMA_CS[3] in this example. 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, and this depends on the boot mode. For NOR boot mode; the on-chip bootloader requires that the image be stored in NOR flash on EMA_CS[2]. For NAND boot mode, the bootloader requires that the boot image is stored 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.

This figure shows how two multiplane NAND flash devices with two chip selects each would connect to the EMIFA. In this case if NAND is the boot memory, then the boot image needs to be stored in the NAND area selected by EMA_CS[3]. Part of the application image could spill over into the NAND regions selected by other EMIFA chip selects; but would rely on the code stored in the EMA_CS[3] area to bootload it.

The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk, and signal timing. These rules, when followed, result in a reliable DDR2/mDDR memory system without the need for a complex timing closure process.

The DDR2/mDDR keep out region is defined for this purpose and is shown in Figure 5-21. The size of this region varies with the placement and DDR routing. Additional clearances required for the keep out region are shown in Table 5-30. DDR2/mDDR Device DDR2/mDDR Controller A1 A1 Region should encompass all DDR2/mDDR circuitry and varies depending on placement. Non-DDR2/mDDR signals should not be routed on the DDR signal layers within the DDR2/mDDR keep out region. Non-DDR2/mDDR signals may be routed in the region provided they are routed on layers separated from DDR2/mDDR signal layers by a ground layer. No breaks should be allowed in the reference ground layers in this region. In addition, the 1.8 V power plane should cover the entire keep out region. Figure 5-21.

VREF is intended to be half the DDR2/mDDR power supply voltage and should be created using a resistive divider as shown in Figure 5-18. Other methods of creating VREF are not recommended. Figure 5-22 shows the layout guidelines for VREF. VREF Bypass Capacitor DDR2/mDDR Device A1 VREF Nominal Minimum Trace Width is 20 Mils DDR2/mDDR A1 Neck down to minimum in BGA escape regions is acceptable. Narrowing to accomodate via congestion for short distances is also acceptable. Best performance is obtained if the width of VREF is maximized. Figure 5-22.

Instead, the boundary scan cells are tapped-off to the DDR PHY and there is the equivalent of a multiplexer inside the DDR PHY which selects between functional and boundary scan paths. The implication for boundary scan is that the DDR pins will not support the SAMPLE function of the output enable cells on the DDR pins and this is a violation of IEEE 1149.1. Full EXTEST and PRELOAD capability is still available. 140 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Links: OMAP-L138 Copyright © 2009–2013, Texas Instruments Incorporated OMAP-L138 www.ti.com SPRS586F – JUNE 2009 – REVISED AUGUST 2013 5.12 Memory Protection Units The MPU performs memory protection checking. It receives requests from a bus master in the system and checks the address against the fixed and programmable regions to see if the access is allowed. If allowed, the transfer is passed unmodified to its output bus (to the targeted address). If the transfer is illegal (fails the protection check) then the MPU does not pass the transfer to the output bus but rather services the transfer internally back to the input bus (to prevent a hang) returning the fault status to the requestor as well as generating an interrupt about the fault. The following features are supported by the MPU: • Provides memory protection for fixed and programmable address ranges. • Supports multiple programmable address region. • Supports secure and debug access privileges. • Supports read, write, and execute access privileges. • Supports privid(8) associations with ranges. • Generates an interrupt when there is a protection violation, and saves violating transfer parameters. • MMR access is also protected.

This is impacted by trace width, trace spacing, distance between planes, and dielectric material. Verify with a proper PCB manufacturing tool that the trace geometry for both data signal pairs results in exactly 100 ohms differential impedance traces. Table 5-47 shows the routing specifications for the data and REFCLK signals . Table 5-47.

The SATA interface requires a LVDS differential clock source to be provided at signals SATA_REFCLKP and SATA_REFCLKN. The clock source should be placed physically as close to the processor as possible. Table 5-49 shows the requirements for the clock source. 150 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Links: OMAP-L138 Copyright © 2009–2013, Texas Instruments Incorporated OMAP-L138 www.ti.com SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Table 5-49.

Data is written to the shift register before transmission occurs and is read from the buffer at the end of transmission. The SPI can operate either as a master, in which case, it initiates a transfer and drives the SPIx_CLK pin, or as a slave. Four clock phase and polarity options are supported as well as many data formatting options. SPIx_SIMO SPIx_SOMI Peripheral Configuration Bus Interrupt and DMA Requests 16-Bit Shift Register 16-Bit Buffer SPIx_ENA GPIO Control (all pins) State Machine SPIx_SCS Clock Control SPIx_CLK Figure 5-36. Block Diagram of SPI Module The SPI supports 3-, 4-, and 5-pin operation with three basic pins (SPIx_CLK, SPIx_SIMO, and SPIx_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 are other slave devices on the same SPI port. The device will only shift data and drive the SPIx_SOMI pin when SPIx_SCS is held low. In slave mode, SPIx_ENA is an optional output. The SPIx_ENA output provides the status of the internal transmit buffer (SPIDAT0/1 registers). In four-pin mode with the enable option, SPIx_ENA is asserted only when the transmit buffer is full, indicating that the slave is ready to begin another transfer. In five-pin mode, the SPIx_ENA is additionally qualified by SPIx_SCS being asserted. This allows a single handshake line to be shared by multiple slaves on the same SPI bus. In master mode, the SPIx_ENA pin is an optional input and the master can be configured to delay the start of the next transfer until the slave asserts SPIx_ENA. The addition of this handshake signal simplifies SPI communications and, on average, increases SPI bus throughput since the master does not need to delay each transfer long enough to allow for the worst-case latency of the slave device. Instead, each transfer can begin as soon as both the master and slave have actually serviced the previous SPI transfer. 170 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Links: OMAP-L138 Copyright © 2009–2013, Texas Instruments Incorporated OMAP-L138 www.ti.com SPRS586F – JUNE 2009 – REVISED AUGUST 2013 Optional − Slave Chip Select SPIx_SCS SPIx_SCS Optional Enable (Ready) SPIx_ENA SPIx_ENA SPIx_CLK SPIx_CLK SPIx_SOMI SPIx_SOMI SPIx_SIMO SPIx_SIMO MASTER SPI SLAVE SPI Figure 5-37.

The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps 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 device to the PHY. The MDIO module controls PHY configuration and status monitoring. Both the EMAC and the MDIO modules interface to the device through a custom interface that allows efficient data transmission and reception. This custom interface is referred to as the EMAC control module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to multiplex and control interrupts. 5.22.1 EMAC Peripheral Register Description(s) Table 5-96.

The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface to interrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIO module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the negotiation results, and configure required parameters in the EMAC module for correct operation. The module is designed to allow almost transparent operation of the MDIO interface, with very little maintenance from the core processor. Only one PHY may be connected at any given time. 5.23.1 MDIO Register Description(s) Table 5-106.

Each controller operates independently from the other and only one of them is active at any given time. • The Raster Controller handles the synchronous LCD interface. It provides timing and data for constant graphics refresh to a passive display. It supports a wide variety of monochrome and full-color display types and sizes by use of programmable timing controls, a built-in palette, and a gray-scale/serializer. Graphics data is processed and stored in frame buffers. A frame buffer is a contiguous memory block in the system. A built-in DMA engine supplies the graphics data to the Raster engine which, in turn, outputs to the external LCD device. • The LIDD Controller supports the asynchronous LCD interface. It provides full-timing programmability of control signals (CS, WE, OE, ALE) and output data. The maximum resolution for the LCD controller is 1024 x 1024 pixels. The maximum frame rate is determined by the image size in combination with the pixel clock rate. For details, see SPRAB93. Table 5-109 lists the LCD Controller registers. Table 5-109.

The host port interface (UHPI) provides a parallel port interface through which an external host processor can directly access the processor's resources (configuration and program/data memories). The external host device is asynchronous to the CPU clock and functions as a master to the HPI interface. The UHPI enables a host device and the processor to exchange information via internal or external memory. Dedicated address (HPIA) and data (HPID) registers within the UHPI provide the data path between the external host interface and the processor resources. A UHPI control register (HPIC) is available to the host and the CPU for various configuration and interrupt functions. 5.25.2 HPI Peripheral Register Description(s) Table 5-113.

The Host has read/write access to the HPIA registers. The CPU has only read access to the HPIA registers. Reserved There are two 32-bit HPIA registers: HPIAR for read operations and HPIAW for write operations. The HPI can be configured such that HPIAR and HPIAW act as a single 32-bit HPIA (single-HPIA mode) or as two separate 32-bit HPIAs (dual-HPIA mode) from the perspective of the Host. The CPU can access HPIAW and HPIAR independently.

It is designed to interface cleanly with high-speed analog-to-digital converters (ADCs) or digital-to-analog converters (DACs) with up to 16-bit data width (per channel). It may also be interconnected with field-programmable gate arrays (FPGAs) or other uPP devices to achieve high-speed digital data transfer. It can operate in receive mode, transmit mode, or duplex mode, in which its individual channels operate in opposite directions. The uPP peripheral includes an internal DMA controller to maximize throughput and minimize CPU overhead during high-speed data transmission. All uPP transactions use the internal DMA to provide data to or retrieve data from the I/O channels. The DMA controller includes two DMA channels, which typically service separate I/O channels. The uPP peripheral also supports data interleave mode, in which all DMA resources service a single I/O channel. In this mode, only one I/O channel may be used. The features of the uPP include: • Programmable data width per channel (from 8 to 16 bits inclusive) • Programmable data justification – Right-justify with zero extend – Right-justify with sign extend – Left-justify with zero fill • Supports multiplexing of interleaved data during SDR transmit • Optional frame START signal with programmable polarity • Optional data ENABLE signal with programmable polarity • Optional synchronization WAIT signal with programmable polarity • Single Data Rate (SDR) or Double data Rate (DDR, interleaved) interface – Supports multiplexing of interleaved data during SDR transmit – Supports demultiplexing and multiplexing of interleaved data during DDR transfers Copyright © 2009–2013, Texas Instruments Incorporated Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Links: OMAP-L138 237 OMAP-L138 SPRS586F – JUNE 2009 – REVISED AUGUST 2013 www.ti.com 5.26.1 uPP Register Descriptions Table 5-117.

The current date and time is tracked in a set of counter registers that update once per second. The time can be represented in 12-hour or 24-hour mode. The calendar and time registers are buffered during reads and writes so that updates do not 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 once per minute or once per day. In addition, the RTC can interrupt the CPU every time the calendar and time registers 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 Figure 5-84 shows a block diagram of the RTC.

The RTC also has a separate power supply that is isolated from the rest of the system. When the CPU and other peripherals are without power, the RTC can remain powered to preserve the current time and calendar information. Even if the RTC is not used, it must remain powered when the rest of the device is powered. The source for the RTC reference clock may be provided by a crystal or by an external clock source. The RTC has an internal oscillator buffer to support direct operation with a crystal. The crystal is connected between pins RTC_XI and RTC_XO. RTC_XI is the input to the on-chip oscillator and RTC_XO is the output 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 is connected to RTC_XI, and RTC_XO is left unconnected. If the RTC is not used, the RTC_XI pin should be held either low or high, RTC_XO should be left unconnected, RTC_CVDD should be connected to the device CVDD and RTC_VSS should remain grounded.

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 internal register. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in different interrupt/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 device GPIO peripheral supports the following: • Up to 144 Pins 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/or falling edges on the pin. – The interrupt requests within each bank are combined (logical or) to create eight unique bank level interrupt requests. – The bank level interrupt service routine may poll the INTSTATx register for its bank to determine which pin(s) have triggered the interrupt. – GPIO Banks 0, 1, 2, 3, 4, 5, 6, 7, and 8 Interrupts assigned to ARM INTC Interrupt Requests 42, 43, 44, 45, 46, 47, 48, 49, and 50 respectively – GPIO Banks 0, 1, 2, 3, 4, 5, 6, 7, and 8 Interrupts assigned to DSP Events 65, 41, 49, 52, 54, 59, 62, 72, and 75 respectively – GPIO Banks 0, 1, 2, 3, 4, and 5 are assigned to EDMA events 6, 7, 22, 23, 28, 29, and 29 respectively on Channel Controller 0 and GPIO Banks 6, 7, and 8 are assigned to EDMA events 16, 17, and 18 respectively on Channel Controller 1. • Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIO signal(s). This allows multiple firmware processes to toggle GPIO output signals without critical section protection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching to anther 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 can be toggled by direct write to the output register(s). • Output register, when read, reflects output drive status. This, in addition to the input register reflecting pin status and open-drain I/O cell, allows wired logic be implemented. The memory map for the GPIO registers is shown in Table 5-135.

The INTC also supports posting events back to the device level host CPU. • A Switched Central Resource (SCR) for connecting the various internal and external masters to the resources inside the PRUSS. The two PRUs can operate completely independently or in coordination with each other. The PRUs can also work in coordination with the device level host CPU. This is determined by the nature of the program which is loaded into the PRUs instruction memory. Several different signaling mechanisms are available between the two PRUs and the device level host CPU. The PRUs are optimized for performing embedded tasks that require manipulation of packed memory mapped data structures, handling of system events that have tight realtime constraints and interfacing with systems external to the device. The PRUSS comprises various distinct addressable regions. Externally the subsystem presents a single 64Kbyte range of addresses. The internal interconnect bus (also called switched central resource, or SCR) of the PRUSS decodes accesses for each of the individual regions. The PRUSS memory map is documented in Table 5-139 and in Table 5-140. Note that these two memory maps are implemented inside the PRUSS and are local to the components of the PRUSS. Table 5-139.

Data RAM0 is intended to be the primary data memory for PRU0 and Data RAM1 is intended to be the primary data memory for PRU1. However for passing information between PRUs, each PRU can access the data ram of the ‘other’ PRU through address 0x0000 2000. The global view of the PRUSS internal memories and control ports is documented in Table 5-141. The offset addresses of each region are implemented inside the PRUSS but the global device memory mapping places the PRUSS slave port in the address range 0x01C3 0000-0x01C3 FFFF. The PRU0 and PRU1 can use either the local or global addresses to access their internal memories, but using the local addresses will provide access time several cycles faster than using the global addresses. This is because when accessing via the global address the access needs to be routed through the switch fabric outside PRUSS and back in through the PRUSS slave port.

TRST holds the debug and boundary scan logic in reset (normal DSP operation) when pulled low (its default state). Since TRST has an internal pull-down resistor, this ensures that at power up the device functions in its normal (non-test) operation mode if TRST is not connected. Otherwise, TRST should be driven inactive by the emulator or boundary scan controller. Boundary scan test cannot be performed while the TRST pin is pulled low. Table 5-146.

The debugger can configure the TAP router for serially linking up to 16 TAP controllers or individually scanning one of the TAP controllers without disrupting the IR state of the other TAPs. 5.34.3.1 Adding TAPS to the Scan Chain The TAP router must be programmed to add additional TAPs to the scan chain. The following JTAG scans must be completed to add the ARM926EJ-S to the scan chain. A Power-On Reset (POR) or the JTAG Test-Logic Reset state configures the TAP router to contain only the router’s TAP. Router TDO TDI CLK Steps TMS Router ARM926EJ-S/ETM Figure 5-88.

The device requires that both TRST and RESET be asserted upon power up to be properly initialized. While RESET initializes the device, TRST initializes the device's emulation logic. Both resets are required for proper operation. While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for the device to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG port interface and device's emulation logic in the reset state. TRST only needs to be released when it is necessary to use a JTAG controller to debug the device or exercise the device's boundary scan functionality. Note: TRST is synchronous and must be clocked by TCK; otherwise, the boundary scan logic may not respond as expected after TRST is asserted. RESET must be released only in order for boundary-scan JTAG to read the variant field of IDCODE correctly. Other boundary-scan instructions work correctly independent of current state of RESET. For maximum reliability, the device includes an internal pulldown (IPD) on the TRST pin to ensure that TRST will always be asserted upon power up and the device's internal emulation logic will always be properly initialized. JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG controllers may not drive TRST high but expect the use of a pullup resistor on TRST. When using this type of JTAG controller, assert TRST to initialize the device after powerup and externally drive TRST high before attempting any emulation or boundary scan operations.

The tool's support documentation is electronically available within the Code Composer Studio™ Integrated Development Environment (IDE). The following products support development of the device applications: Software Development Tools: Code Composer Studio™ Integrated Development Environment (IDE): including Editor C/C++/Assembly Code Generation, and Debug plus additional development tools Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target software needed to support any application. Hardware Development Tools: Extended Development System (XDS™) Emulator For a complete listing of development-support tools for the device, visit the Texas Instruments web site on the Worldwide Web at http://www.ti.com uniform resource locator (URL). For information on pricing and availability, contact the nearest TI field sales office or authorized distributor. 6.1.2 Device Nomenclature To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all DSP devices and support tools. Each DSP commercial family member has one of three prefixes: X, P or NULL (e.g., OMAP-L138). Texas Instruments recommends two of three possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS). Device development evolutionary flow: X Experimental device that is not necessarily representative of the final device's electrical specifications. P Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification. NULL Fully-qualified production device. Support tool development evolutionary flow: TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing. TMDS Fully qualified development-support product. X and P devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." Null devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies. Predictions show that prototype devices (X or P) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.

DSP Reference Guides SPRUG82 TMS320C674x DSP Cache User's Guide. Explains the fundamentals of memory caches and describes how the two-level cache-based internal memory architecture in the TMS320C674x digital signal processor (DSP) can be efficiently used in DSP applications. Shows how to maintain coherence with external memory, how to use DMA to reduce memory latencies, and how to optimize your code to improve cache efficiency. The internal memory architecture in the C674x DSP is organized in a two-level hierarchy consisting of a dedicated program cache (L1P) and a dedicated data cache (L1D) on the first level. Accesses by the CPU to the these first level caches can complete without CPU pipeline stalls. If the data requested by the CPU is not contained in cache, it is fetched from the next lower memory level, L2 or external memory. 278 SPRUFE8 TMS320C674x DSP CPU and Instruction Set Reference Guide.
