Throughout this document, unless otherwise noted, VCE6467T, refers to the VCE6467T and AVCE6467T devices. The VCE6467T enables OEMs and ODMs to quickly bring to market devices featuring robust operating systems support, rich user interfaces, high processing performance, and long battery life through the maximum flexibility of a fully integrated mixed processor solution. The dual-core architecture of the VCE6467T provides benefits of both DSP and Reduced Instruction Set Computer (RISC) technologies, incorporating a high-performance TMS320C64x+ 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 ARM core incorporates: • A coprocessor 15 (CP15) and protection module • Data and program Memory Management Units (MMUs) with table look-aside buffers. • Separate 16K-byte instruction and 8K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT). The TMS320C64x+™ DSPs are the highest-performance fixed-point DSP generation in the TMS320C6000™ DSP platform. It is based on an enhanced version of the second-generation high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making these DSP cores an excellent choice for digital media applications. The C64x is a code-compatible member of the C6000™ DSP platform. The TMS320C64x+ DSP is an enhancement of the C64x+ DSP with added functionality and an expanded instruction set. Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP and C64x+ CPU, respectively. With performance of up to 8000 million instructions per second (MIPS) at a clock rate of 1 GHz, the C64x+ core offers solutions to high-performance DSP programming challenges. The DSP core possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. The C64x+ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly independent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs). The eight functional units include instructions to accelerate the performance in video and imaging applications. The DSP core can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 4000 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 8000 MMACS. For more details on the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide (literature number SPRU732). The VCE6467T also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices. The VCE6467T core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a 256K-bit direct mapped cache and the Level 1 data cache (L1D) is a 640K-bit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 512K-bit memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two.

The Ethernet Media Access Controller (EMAC) provides an efficient interface between the VCE6467T and the network. The VCE6467T EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps in either half- or full-duplex mode; and 1000Base-TX (1 Gbps) in full-duplex mode with hardware flow control and quality of service (QOS) support. The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system. Once a PHY candidate has been selected by the ARM, the MDIO module transparently monitors its link state by reading the PHY status register. Link change events are stored in the MDIO module and can optionally interrupt the ARM, allowing the ARM to poll the link status of the device without continuously performing costly MDIO accesses. The PCI, HPI, I2C, SPI, USB2.0, and VLYNQ ports allow the VCE6467T to easily control peripheral devices and/or communicate with host processors. The VCE6467T also includes a High-Definition Video/Imaging Co-processor (HDVICP) and Video Data Conversion Engine (VDCE) to offload many video and imaging processing tasks from the DSP core, making more DSP MIPS available for common video and imaging algorithms. For more information on the HDVICP enhanced codecs, such as H.264 and MPEG4, please contact your nearest TI sales representative. 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 later in this document and the associated peripheral reference guides. The VCE6467T has a complete set of development tools for both the ARM and DSP. These include C compilers, a DSP assembly optimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility into source code execution. 4 Digital Media System-on-Chip (DMSoC) Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T Copyright © 2011, Texas Instruments Incorporated VCE6467T, AVCE6467T www.ti.com 1.3 SPRS690 – MARCH 2011 Functional Block Diagram Figure 1-1 shows the functional block diagram of the device.

The C64x+ DSP core is code-compatible with the C6000™ DSP platform and supports features of the C64xT DSP family. 2.3 ARM Subsystem The ARM Subsystem is designed to give the ARM926EJ-S (ARM9) master control of the device. In general, the ARM is responsible for configuration and control of the device; including the DSP Subsystem, the VPSS Subsystem, and a majority of the peripherals and external memories. The ARM Subsystem includes the following features: • ARM926EJ-S RISC processor • ARMv5TEJ (32/16-bit) instruction set • Little endian operation • Co-Processor 15 (CP15) • MMU • 16KB Instruction cache • 8KB Data cache • Write Buffer • 32KB Internal Tightly-Coupled Memory (TCM) RAM (32-bit wide access) • 8KB Internal ROM (ARM bootloader for non-EMIFA boot options) • Embedded Trace Module and Embedded Trace Buffer (ETM/ETB) • ARM Interrupt Controller • PLL Controller • Power and Sleep Controller (PSC) • System Module 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) • Separate instruction and data Caches • Write buffer • Separate instruction and data Tightly-Coupled Memories (TCMs) [internal RAM] interfaces • Separate instruction and data AHB bus interfaces • Embedded Trace Module and Embedded Trace Buffer (ETM/ETB) Device Overview Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T 9 VCE6467T, AVCE6467T SPRS690 – MARCH 2011 www.ti.com 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, Tightly-Coupled Memories (TCMs), 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 The ARM926EJ-S MMU provides virtual memory features required by operating systems such as Linux®, Windows® CE, Ultron®, ThreadX®, etc. 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 8KB. 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. 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. 10 Device Overview Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T VCE6467T, AVCE6467T www.ti.com 2.3.5 SPRS690 – MARCH 2011 Tightly Coupled Memory (TCM) ARM internal RAM is provided for storing real-time and performance-critical code/data and the Interrupt Vector table. ARM internal ROM enables non-EMIFA boot options, such as NAND and UART. The RAM and ROM memories interfaced to the ARM926EJ-S via the tightly coupled memory interface that provides for separate instruction and data bus connections. Since the ARM TCM does not allow instructions on the D-TCM bus or data on the I-TCM bus, an arbiter is included so that both data and instructions can be stored in the internal RAM/ROM. The arbiter also allows accesses to the RAM/ROM from extra-ARM sources (e.g., EDMA or other masters). The ARM926EJ-S has built-in DMA support for direct accesses to the ARM internal memory from a non-ARM master. Because of the time-critical nature of the TCM link to the ARM internal memory, all accesses from non-ARM devices are treated as DMA transfers. Instruction and Data accesses are differentiated via accessing different memory map regions, with the instruction region from 0x0000 through 0x7FFF and data from 0x10000 through 0x17FFF. The instruction region at 0x0000 and data region at 0x10000 map to the same physical 32-KB TCM RAM. Placing the instruction region at 0x0000 is necessary to allow the ARM Interrupt Vector table to be placed at 0x0000, as required by the ARM architecture. The internal 32-KB RAM is split into two physical banks of 16KB each, which allows simultaneous instruction and data accesses to be accomplished if the code and data are in separate banks. 2.3.6 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. 2.3.7 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 VCE6467T 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 VCE6467T 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. 2.3.8 ARM Memory Mapping The ARM memory map is shown in Section 2.6, Memory Map Summary of this document. The ARM has access to memories shown in the following sections. 2.3.8.1 ARM Internal Memories The ARM has access to the following ARM internal memories: • 32KB ARM Internal RAM on TCM interface, logically separated into two 16KB pages to allow simultaneous access on any given cycle if there are separate accesses for code (I-TCM bus) and data (D-TCM) to the different memory regions. • 8KB ARM Internal ROM 2.3.8.2 External Memories The ARM has access to the following external memories: • DDR2 Synchronous DRAM • Asynchronous EMIF / NOR Flash / NAND Flash • ATA Device Overview Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T 11 VCE6467T, AVCE6467T SPRS690 – MARCH 2011 2.3.8.3 www.ti.com DSP Memories The ARM has access to the following DSP memories: • L2 RAM • L1P RAM • L1D RAM 2.3.8.4 ARM-DSP Integration VCE6467T ARM and DSP integration features are as follows: • DSP visibility from ARM’s memory map, see Section 2.6, Memory Map Summary, for details • Boot Modes for DSP - see Device Configurations section, Section 3.4.1, DSP Boot, for details • ARM control of DSP boot / reset - see Device Configurations section, Section 3.4.2.4, ARM Boot, for details • ARM control of DSP isolation and powerdown / powerup - see Section 3, Device Configurations, for details • ARM & DSP Interrupts - see Section 6.8.1, ARM CPU Interrupts, and Section 6.8.2, DSP Interrupts, for details 2.3.9 Peripherals The ARM9 has access to all of the peripherals on the VCE6467T device. 2.3.10 PLL Controller (PLLC) The ARM Subsystem includes the PLL Controller. The PLL Controller contains a set of registers for configuring VCE6467T’s two internal PLLs (PLL1 and PLL2). The PLL Controller provides the following configuration and control: • PLL Bypass Mode • Set PLL multiplier parameters • Set PLL divider parameters • PLL power down • Oscillator power down The PLLs are briefly described in this document in the Clocking section. For more detailed information on the PLLs and PLL Controller register descriptions, see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). 2.3.11 Power and Sleep Controller (PSC) The ARM Subsystem includes the Power and Sleep Controller (PSC). Through register settings accessible by the ARM9, the PSC provides two levels of power savings: peripheral/module clock gating and power domain shut-off. Brief details on the PSC are given in Section 6.3, Power Supplies. For more detailed information and complete register descriptions for the PSC, see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). 2.3.12 ARM Interrupt Controller (AINTC) The ARM Interrupt Controller (AINTC) accepts device interrupts and maps them to either the ARM’s IRQ (interrupt request) or FIQ (fast interrupt request). The ARM Interrupt Controller is briefly described in this document in the Interrupts section. For detailed information on the ARM Interrupt Controller, see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). 12 Device Overview Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T VCE6467T, AVCE6467T www.ti.com SPRS690 – MARCH 2011 2.3.13 System Module The ARM Subsystem includes the System module. The System module consists of a set of registers for configuring and controlling a variety of system functions. For details and register descriptions for the System module, see Section 3, Device Configurations and see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). 2.3.14 Power Management VCE6467T has several means of managing power consumption. There is extensive use of clock gating, which reduces the power used by global device clocks and individual peripheral clocks. Clock management can be utilized to reduce clock frequencies in order to reduce switching power. For more details on power management techniques, see Section 3, Device Configurations, Section 6, Peripheral and Electrical Specifications, and see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). VCE6467T gives the programmer full flexibility to use any and all of the previously mentioned capabilities to customize an optimal power management strategy. Several typical power management scenarios are described in the following sections. 2.4 DSP Subsystem The DSP Subsystem includes the following features: • C64x+ DSP CPU • 32KB L1 Program (L1P)/Cache (up to 32KB) • 32KB L1 Data (L1D)/Cache (up to 32KB) • 128KB Unified Mapped RAM/Cache (L2) • Little endian 2.4.1 C64x+ DSP CPU Description The C64x+ Central Processing Unit (CPU) consists of eight functional units, two register files, and two data paths as shown in Figure 2-1. The two general-purpose register files (A and B) each contain 32 32-bit 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, 40-bit 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 C64x+ CPU extends the performance of the C64x core through enhancements and new features. Each C64x+ .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 audio and other high-precision algorithms on a variety of signed and unsigned 32-bit data types.

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 C64x+ core enhances the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2 comparisons were only available on the .L units. On the C64x+ 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 C64x+ 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 C64x+ 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 free-running time-stamp counter is implemented in the CPU which is not sensitive to system stalls.

VCE6467T Software APIs API NAME DESCRIPTION VCE6467T Client RvV2oipClientAdminToolsExecuteOnSlave This function sends a command to execute from Master to Slave. RvV2oipClientAdminToolsPutFileOnSlave This function sends a file from the Master ARM processor to the Slave processor. RvV2oipClientConstruct This API is called to construct a new VCE6467T Client instance and set its configuration to the default values. This should be the first API to be called when the VCE6467T Client is initialized. RvV2oipClientDestruct This API is called to destruct a VCE6467T Client. RvV2oipClientRefresh This API is called to initiate a Refresh procedure of the VCE6467T Client. A Refresh procedure drops all calls from the VCE6467T Client, unregisters, reconfigures the VCE6467T Client module, and re-registers to the server. In a Refresh procedure only partial reconfiguration is allowed, since the system (including the VCE6467T Client, MTF, SIP, and H.323 modules) does not restart and the same local IP address is bound. The configuration buffer supplied by the application must not be released until the Refresh procedure is completed (i.e., RvV2oipClientRegisteredEv is called). During the Refresh configuration process, the parameters that are not reconfigured will remain as before. RvV2oipClientRegister This API is called to start a registration process of the VCE6467T Client to the configured registrar/proxy in SIP. RvV2oipClientRegisteredEv This event is called when a registration to network process was completed. RvV2oipClientRestart This API is called to initiate a Restart procedure of the VCE6467T Client. In a Restart procedure, the VCE6467T Client is stopped (including the MTF and SIP modules) and the local IP address is unbound. The VCE6467T Client then reconfigures, and after 2 seconds, starts again with the new configuration and re-registers to the server. In a Restart procedure, the VCE6467T Client can be fully reconfigured. The RvV2oipClientRestart can be called only when the VCE6467T Client is not registered to the server. The configuration buffer supplied by the application must not be released until the Restart procedure is completed (i.e., RvV2oipClientRegisteredEv is called). During the Restart configuration process, the parameters that are not reconfigured will be set to their default values. RvV2oipClientSetClientCallbacks This API is called to set the client callbacks in the client object. RvV2oipClientSetClientCallbacksByIndex This API is called to set the client with more than one set of callbacks in the client object. RvV2oipClientSetScreenResolution This API is called to set the configuration parameters of the screen resolution. RvV2oipClientStart This API is called to start the VCE6467T Client process. All modules of the VCE6467T Client (including MTF, SIP, and the media module interface) are initialized here. In this API, the VCE6467T Client starts listening on the local IP address with the configured ports for SIP. Only after this API is completed successfully, the VCE6467T Client can register to a server/gatekeeper and make or receive calls. RvV2oipClientGetStatus This API is called to get the current client status. RvV2oipClientTroubleNotifierEv This event is called to notify the application about a problem that has occurred in the VCE6467T Client. The application can use the notification string to help the user troubleshoot the problem. RvV2oipClientUnRegister This API is called to start an un-registration process of the VCE6467T Client from the registrar/proxy. Calling this API will cause all calls in the VCE6467T Client to be dropped. RvV2oipClientUnregisteredEv This event is called when an un-registration process has ended. RvV2oipClientRegistrationProcessComplete dEv This event is called when the registration process to MTF and networks is completed. After the registration process was successfully completed, the user can start to make and receive calls. RvV2oipClientUnRegistrationProcessComple This event is called when the un-registration process from MTF and networks is completed. tedEv HV2OIP Handle to a VCE6467T Client object. HV2OIPAPP Application handle to a VCE6467T Client object. This handle can be used as an application context. HV2OIPCALL Handle to a VCE6467T Client call object. HV2OIPCALLAPP Application handle to a VCE6467T Client call object. This handle can be used as an application context for the call. HV2OIPWINAPP Application handle to a VCE6467T Client window object.

RvV2oipClientCallStateReason This structure contains additional information related to the state of a VCE6467T call. RvV2oipClientCallMtfStateReason This enumeration defines the reason for the state of a V2oIP call. RvV2oipCallRejectReasonType This enumeration defines the reason a call was locally rejected. RvV2oipIncomingCallParams This structure specifies the incoming call information. RvV2oipMsgHandle This is a handle to a message object. RvV2oipClientGetAppCfgParamsEv This event is called to get the application configuration parameters when RvV2oipClientGetConfig is called. RvV2oipClientGetCfgParam This API is called to retrieve one configuration parameter. RvV2oipClientGetConfig This API is called to get the current configuration of the VCE6467T Client. The configuration is returned in a text buffer in the same format as the configuration file. RvV2oipClientSetAppCfgParamEv This event is called to set an application configuration parameter. The application can add its own configuration parameters to the configuration file of the VCE6467T Client, under the group name APPLICATION or any other group name unknown to the VCE6467T Client. This event will be called for each such parameter. RvV2oipClientSetCfgCallbacks This API is called to set the configuration module events in the VCE6467T Client object. RvV2oipClientSetConfig This API is called to configure the VCE6467T Client and application. Configuration parameters that are not in the configuration buffer will keep their current value. If the caller of the API is not authorized a WRITE permission on one or more parameters in the file, the API will not change the current configuration and will return with an error code. RvV2oipClientSetConfigParam This API is called to set a specific configuration parameter. If the configuration fails for permission or state reasons, this function will return an error value. RvV2oipClientRemoveCfgParam This API is called to remove a parameter from a given configuration buffer. RvV2oipCfgGroupType This enumeration defines the configuration group types. RvV2oipCfgParamObj This structure defines the configuration parameter object. RvV2oipClientCfgCallbacks This structure specifies the VCE6467T Client configuration events RvV2oipClientLogApplMsg This API is called when the application wants to log its own messages in the log file under the APPL log source. The application messages will be logged to the log file only if the IPP_USERAPP log source is set under IppLogOptions in the configuration file. RvV2oipClientLogFuncT This is the type definition for the logging event function. RvV2oipClientSetLogCB This API is called to set the callback function that is called when logging messages are being written. RvV2oipClientlogErrorType This enumeration defines the logging type of an application log message.

For information on pricing and availability, contact the nearest TI field sales office or authorized distributor. 2.9.2 Device and Development-Support Tool 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: TMX, TMP, or TMS (e.g.,VCE6467TZUTL1). 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: TMX Experimental device that is not necessarily representative of the final device's electrical specifications. TMP Final silicon die that conforms to the device's electrical specifications but has not completed quality and reliability verification. TMS 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. TMX and TMP devices and TMDX development-support tools are shipped against the following disclaimer: "Developmental product is intended for internal evaluation purposes." TMS 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. 80 Device Overview Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T VCE6467T, AVCE6467T www.ti.com SPRS690 – MARCH 2011 Predictions show that prototype devices (TMX or TMP) 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. TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, ZUT), the temperature range (for example, "Blank" is the commercial temperature range), and the device speed range in megahertz or gigahertz (for example, "L1" is the default [1-GHz DSP, 500-MHz ARM9, 108-MHz VPIF, 400-MHz DDR2]).

As described in the Section 6.3.4, VCE6467T Power and Clock Domains, the VCE6467T has one single power domain—the “Always On” power domain. Within this power domain, the VCE6467T utilizes local clock gating via the Power and Sleep Controller (PSC) to achieve power savings. For more details on the PSC, see Section 6.3.5, Power and Sleep Controller (PSC) and the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). Some of the VCE6467T peripherals support additional power saving features. For more details on power saving features supported, see the peripheral-specific reference guides [listed/linked in the TMS320DM646x DMSoC Peripherals Overview Reference Guide (literature number SPRUEQ0). Most VCE6467T 3.3-V I/Os can be powered-down to reduce power consumption. The VDD3P3V_PWDN register in the System Module (see Figure 3-1 ) is used to selectively power down unused 3.3-V I/O pins. Note: To save power, all other I/O buffers are powered down by default. Before using these pins, the user must program the VDD3P3V_PWDN register to power up the corresponding I/O buffers. For a list of multiplexed pins on the device and the pin mux group each pin belongs to, see Section 3.7.3, Pin Multiplexing Details.

In addition, the System Module Video Clock Control (VIDCLKCTL), TSIF Control (TSIFCTL), and Clock and Oscillator Control (CLKCTL) registers configure the clock sources to the VPIF, TSIF, CRGEN peripherals, and the Auxiliary Oscillator. The selected Video, TSIF, and CRGEN module input clocks are disabled using the System Module Video Source Clock Disable (VSCLKDIS) register. Note: To ensure glitch-free operation, the clock should be disabled before changing the clock source frequency or muxing via the VIDCLKCTL and TSIFCTL. 3.3.1 Clock Configurations after Device Reset After device reset, the user is responsible for programming the PLL Controllers (PLLC1 and PLLC2) and the Power and Sleep Controller (PSC) to bring the device up to the desired clock frequency and the desired peripheral clock state (clock gating or not). For additional power savings, some of the VCE6467T peripherals support clock gating within the peripheral boundary. For more details on clock gating and power saving features supported by a specific peripheral, see the peripheral-specific reference/user's guides [listed/linked in the TMS320DM646x DMSoC Peripherals Overview Reference Guide (literature number SPRUEQ0)]. 3.3.1.1 Device Clock Frequency The VCE6467T defaults to PLL bypass mode. If the ROM bootloader is selected (BTMODE[3:0] ≠ 0100), the bootloader code programs PLLC1 and PLLC2. Section 3.4.1, Boot Modes discusses the different boot modes in more detail. The user must adhere to the various clock requirements when programming the PLLC1 and PLLC2: • PLL multiplier and frequency ranges. For more details on PLL multiplier and frequency ranges, see Section 6.5.1, PLL1 and PLL2. 3.3.1.2 Module Clock State The clock and reset state for each of the modules is controlled by the Power and Sleep Controller (PSC). Table 3-3 shows the default state of each module after a device-level global reset. The VCE6467T device has four different module states—Enable, Disable, SyncReset, or SwRstDisable. For more information on the definitions of the module states, the PSC, and PSC programming, see Section 6.3.5, Power and Sleep Controller (PSC) and the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). 88 Device Configurations Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T VCE6467T, AVCE6467T www.ti.com SPRS690 – MARCH 2011 Table 3-3.

The boot sequence is started automatically after each device-level global reset. For more details on device-level global resets, see Section 6.7, Reset. There are several methods by which the memory and register initialization can take place. Each of these methods is referred to as a boot mode. The boot mode to be used is selected at reset. For more information on the bootmode selections, see Section 3.4.1, Boot Modes. The device is booted through multiple means—primary bootloaders within internal ROM or EMIFA, and secondary user bootloaders from peripherals or external memories. Boot modes, pin configurations, and register configurations required for booting the device, are described in the following subsections. 3.4.1 Boot Modes The VCE6467T boot modes are determined by these device boot and configuration pins. For information on how these pins are sampled at device reset, see Section 6.7.1.2, Latching Boot and Configuration Pins. • BTMODE[3:0] • PCIEN • CS2BW • DSPBOOT The TMS320DM646x DMSoC ARM can boot either from asynchronous EMIF/NOR Flash or from ARM ROM, as determined by the device boot and configuration pins at reset (BTMODE[3:0] and PCIEN). The PCIEN pin configuration is used to select the default configuration of the EMIFA/PCI/HPI pins at reset. This allows the DM646xT DMSoC to be PCI-compliant at reset. When PCIEN = 1, the PCI module controls the multiplexed pins with the appropriate pullup/pulldown configuration. For all other bootmodes (non-PCI bootmodes), the PCIEN must be cleared to "0".

During a hard reset (POR or RESET pin active [low]), the values of the CFG pins (i.e., BTMODE[3:0], CS2BW, PCIEN, DSPBOOT) are propagated through the BOOTCFG register to the Boot Controller. When RESET or POR is de-asserted, the value of the pins is latched. The BOOTCFG value does not change as a result of a soft reset, instead the value latched at the end of the previous global reset is retained. 31 18 15 17 16 RESERVED DSP_BT PCIEN R-0000 0000 0000 00 R-L R-L 9 8 7 4 3 0 RESERVED CS2_BW RESERVED BOOTMODE R-0000000 R-L R-0000 R-LLLL LEGEND: R = Read only; L = Latched pin value; -n = value after reset Figure 3-8.

The ARMBOOT value does not change as a result of a soft reset, instead the last value written is retained. When ROM boot is selected (BTMODE[3:0] ≠ 0100), a jump to the internal TCM ROM (0x0000 8000) is forced into the first fetched instruction word. The embedded ROM boot loader (RBL) code can then perform certain configuration steps, read the BOOTCFG register to determine the desired boot method, and branch to an appropriate secondary loader utility. If EMIFA boot is selected (BTMODE[3:0] = 0100), a jump to the highest branch address (0x0200 0000) is forced into the first fetched instruction word. This must be modified to address 0x4200 0000 in order to map to the EMIFA. The ARM will then continue executing from external memory using the default EMIFA timings until modified by software. Note: that either NOR Flash or ROM must be connected to the first EMIFA chip select space (EM_CS2). The EMIFA does not support direct execution from NAND Flash. 31 5 4 3 1 0 RESERVED ADDRMOD RESERVED TRAMBOOT R-0000 0000 0000 0000 0000 0000 000 R/W-C R-000 R/W-0 LEGEND: R/W = Read/Write; R = Read only; C = Clear; -n = value after reset Figure 3-9.

The default value for this bit is determined by the BOOTMODE configuration bits (BTMODE[3:0]). If BTMODE[3:0] = 0100 [EMIFA direct boot (ROM/NOR)] , then ADDRMOD defaults to "1" so that instruction fetches from the ARM will point to EMIFA CS2 memory space. For all other BTMODE[3:0] values, ADDRMOD defaults to "0" because ARM will boot from its TCM (ROM or RAM). The ADDRMOD value is ignored when TRAMBOOT is set (1) [address modification is disabled]. After branching into the EMIFA CS2 space, software should clear this bit as part of the reset routine so that subsequent IAHB access addresses are not modified. 3:1 RESERVED Reserved. Read returns "0". TRAMBOOT ARM TCM RAM Boot. 0 = Use BTMODE[3:0] selected boot mode 1 = Boot from ITCM RAM This is a "sticky" bit that can be used to force the ARM926 to boot from ITCM RAM. On POR reset, this bit will be initialized to "0" because TCM RAM is not initialized; otherwise, the bit retains the value. After initializing ITCM RAM, software can set this bit so that subsequent Warm Reset (RESET) or Soft Reset will boot from the ITCM. 0 3.4.2.5 DESCRIPTION ARMWAIT Register The ARM Wait State Control (ARMWAIT) register is used to control ARM926 accesses to its TCM RAM. At normal ARM operating frequency, a wait state must be inserted when accessing TCM RAM. When the device is operated at low speeds, performance may be increased by removing the wait state.

The following subsections give more details. 3.5.1 Device and Peripheral Configurations at Device Reset Table 2-6, BOOT Terminal Functions lists the device boot and configuration pins that are latched at device reset for configuring basic device settings for proper device operation. Table 3-13, summarizes the device boot and configuration pins, and the device functions that they affect. Table 3-13. Default Functions Affected by Device Boot and Configuration Pins DEVICE BOOT AND CONFIGURATION PINS BOOT SELECTED PIN MUX CONTROL GLOBAL SETTING PERIPHERAL SETTING BOOTMODE[3:0] Boot Mode PINMUX0/PINMUX1 Registers: Based on BOOTMODE[3:0], the bootloader code programs PINMUX0 and PINMUX1 registers to select the appropriate pin functions required for boot. I/O Pin Power: Based on BOOTMODE[3:0], the bootloader code programs VDD3P3V_PWDN register to power up the I/O pins required for boot. PSC/Peripherals: Based on BOOTMODE[3:0], the bootloader code programs the PSC to put boot-related peripheral(s) in the Enable State, and programs the peripheral(s) for boot operation. CS2BW EMIFA Direct Boot Mode PINMUX0.HPIEN = 0 PINMUX0.PCIEN = 0 PINMUIX0.ATAEN = 0 – The default width of the first EMIFA chip select space (CS2) is determined by the CS2BW value. If CS2BW = 0, the space defaults to 8-bits wide. If CS2BW = 1, it defaults to 16-bits wide. This allows the ARM to make full use of the width of the attached memory device when booting from EMIFA. PCIEN (1) Host Boot: PCIEN selects the type of Host Boot (HPI Boot or PCI Boot) PINMUX0.PCIEN: sets this field to control the PCI pin muxing in . – PSC/Peripheral (Applicable to Host Boot only): Based on the Host Boot type (PCI or HPI), the bootloader code programs the PSC to put the corresponding peripheral in the Enable State, and programs the peripheral for boot operation. (1) (2) (1) (2) Software can modify all PINMUX0 and PINMUX1 bit fields from their defaults. In addition to pin mux control, PCIEN also affects the internal pullup/down resistors of the PCI capable pins. When PCIEN = 0, internal pullup/down resistors on the PCI capable pins are enabled. When PCIEN = 1, internal pullup/down resistors on the PCI capable pins are disabled to be compliant to the PCI Local Bus Specification Revision 2.3.

Default Functions Affected by Device Boot and Configuration Pins (continued) DEVICE BOOT AND CONFIGURATION PINS DSPBOOT BOOT SELECTED Bit = 0, DSP is booted by the ARM Bit =1, DSP boots self from EMIFA PIN MUX CONTROL – GLOBAL SETTING – PERIPHERAL SETTING Note: that either NOR Flash or ROM must be connected to the first EMIFA chip select space (CS2). The EMIFA does not support direct execution from NAND Flash. Code within the EMIFA memory should execute a branch to the actual EMIFA address and then disable the Instruction Address Modification logic (by clearing the ADDRMOD bit in the ARMBOOT register of the System Module). For proper device operation, external pullup/pulldown resistors may be required on these device boot and configuration pins. For discussion situations where external pullup/pulldown resistors are required, see Section 3.8.1, Pullup/Pulldown Resistors. Note: All VCE6467T device configuration inputs (BOOTMODE[3:0], CS2BW, PCIEN, and DSPBOOT) are multiplexed with other functional pins. These pins function as device boot and configuration pins only during device reset. The user must take care of any potential data contention in the system. To help avoid system data contention, the VCE6467T puts these configuration pins into a high-impedance state (Hi-Z) when device reset (RESET or POR) is asserted, and continues to hold them in a high-impedance state until the internal global reset is removed; at which point, the default peripheral (VPIF) will now control these pins. All of the device boot and configuration pin settings are captured in the corresponding bit fields in the BOOTCFG register (see Section 3.4.2.3). The following subsections provide more details on the device configurations determined at device reset: CS2BW, PCIEN, and DSPBOOT. 3.5.2 EMIFA CS2 Bus Width (CS2BW) The default width of the first EMIFA chip select space (CS2) is determined by the CS2BW value. If CS2BW = 0, the space defaults to 8-bits wide. If CS2BW = 1, it defaults to 16-bits wide. This allows the ARM to make full use of the width of the attached memory device when booting from EMIFA. Note: CS2BW only selects the default bus width. The EMIFA bus width may be changed at any time via software by accessing the appropriate EMIFA control register. The default width affects only the first chip select space (CS2). All other chip select spaces default to 8-bits wide and must be modified using the appropriate EMIFA control register if 16-bit operation is desired. 3.5.3 PCI Enable (PCIEN) The PCIEN configuration pin determines if the PCI peripheral is used on this device. If PCIEN = 1 indicating the PCI is used, then the PCI multiplexed pins default to PCI functions, and the pins’ corresponding internal pullup/pulldown resistors are disabled. If PCIEN = 0 indicating the PCI is not used, then the PCI muxed pins default to non-PCI functions (e.g., EMIFA or HPI pin functions), and the pins’ corresponding internal pullup/pulldown resistors are enabled. The PCIEN setting is captured and stored in the BOOTCFG.PCIEN bit field, and also in the PINMUX0.PCIEN bit field. 102 Device Configurations Copyright © 2011, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T VCE6467T, AVCE6467T www.ti.com 3.5.4 SPRS690 – MARCH 2011 DSPBOOT The DSPBOOT input determines DSP operation at reset. For most applications, the ARM is the master device and controls the reset and boot of the DSP. Under this scenario (DSPBOOT = 0), the DSP will remain disabled (held in reset) after reset. The ARM is responsible for releasing DSP from reset. Before releasing DSP from reset, the ARM must transfer a valid DSP boot image to program memory accessible by the DSP (DSP memory, EMIFA or DDR2), and configure the DSP boot address in DSPBOOTADDR register (in SYSTEM module) from which the DSP will begin execution. When DSPBOOT = 1, the DSP will boot itself. Under this scenario, DSP will be released from reset without ARM intervention. The DSP boot address is set to an EMIFA address 0x4220 0000h. DSP will begin execution with instruction (L1P) cache enabled. Note: The DSPBOOT operation is overridden when ARM HPI or PCI boot is selected (BTMODE[3:0] = 001x). This is because ARM HPI/PCI boot selection will force the HPIEN or PCIEN bit in PINMUX0 to ‘1’. This enables UHPI/PCI functions on the EMIFA control and data pins and prevents the DSP from using EMIFA. DSPBOOT is treated as "0" internally when BTMODE[3:0] = 001x, regardless of the value at the configuration pin (The actual pin value should still be latched in the BOOTCFG register of the System Module).

Multiplexed pin are configured both at and after reset. Section 3.5.1, Device and Peripheral Configurations at Device Reset, discusses multiplexed pin control at reset. For more details on multiplexed pins control after reset, see Section 3.7, Multiplexed Pin Configurations. 3.6.1 Switch Central Resource (SCR) Bus Priorities Prioritization within the Switched Central Resource (SCR) is programmable for each master. The register bit fields and default priority levels for VCE6467T bus masters are shown in Table 3-14, VCE6467T Default Bus Master Priorities. The priority levels should be tuned to obtain the best system performance for a particular application. Lower values indicate higher priority. For most masters, their priority values are programmed at the system level by configuring the MSTPRI0, MSTPRI1, and MSTPRI2 registers. Details on the MSTPRI0/1/2 registers are shown in Figure 3-11, Figure 3-12, and Figure 3-13. Table 3-14.

The Pin Multiplex Registers PINMUX0 and PINMUX1 in the System Module are responsiblie for controlling all pin multiplexing functions on the VCE6467T. The default setting of some of the PINMUX0 and PINMUX1 bit fields are configured by configuration pins latched at reset (see Section 3.5.1, Device and Peripheral Configurations at Device Reset). After reset, software may program the PINMUX0 and PINMUX1 registers to switch pin functionalities. The following peripherals have multiplexed pins: VPIF, TSIF0, TSIF1, CRGEN0, CRGEN1, EMIFA, PCI, HPI, ATA, PWM0, PWM1, UART0, UART1, UART2, Audio Clock Selector, the USB USB_DRVVBUS pin, and GPIO. 3.7.1 Pin Muxing Selection At Reset This section summarizes pin mux selection at reset. The configuration pins CS2BW and PCIEN, latched at device reset, determine the default pin muxing. For more details on the default pin muxing at reset, see Section 3.5, Configurations At Reset. 3.7.2 Pin Muxing Selection After Reset The PINMUX0 and PINMUX1 registers in the System Module allow software to select the pin functions. Some pin functions require a combination of PINMUX0/PINMUX1 bit fields. For more details on the combination of the PINMUX bit fields that control each muxed pin, see Section 3.7.3, Pin Multiplexing Details. This section only provides an overview of the PINMUX0 and PINMUX1 registers. For more detailed discussion on how to program each Pin Mux Block, see Section 3.7.3, Pin Multiplexing Details. 3.7.2.1 PINMUX0 Register Description The Pin Multiplexing 0 Register controls the pin function in the EMIFA/ATA/HPI/PCI, TSIF0, TSIF1, CRGEN, Block. The PINMUX0 register format is shown in Figure 3-18 and the bit field descriptions are given in Table 3-22. Some muxed pins are controlled by more than one PINMUX bit field. For the combination of the PINMUX bit fields that control each muxed pin, see Section 3.7.3, Pin Multiplexing Details.

The UART0 pin muxing is controlled by the UART0CTL bit field in the PINMUX1 register and the TSPOMUX, TSSIMUX, and TSSOMUX bit fields in the PINMUX0 register. Muxing options are shown in Table 3-33 and Table 3-34. When UART operation is selected, UART0CTL must be set to either ‘00’ for UART with modem signals or ‘01’ for UART without modem signals. When IrDA/CIR operation is selected, UART0CTL must be set to ‘1x’ to use the IrDA/CIR signals and the modem signal become GPIOs. A TSPOMUX setting of ‘1x’ overrides the modem control mux settings. UART0 can still be used as a UART without modem control or in IrDA/CIR mode based on the UART0CTL bit field value. A TSSIMUX setting of ‘01’ overrides the UART data and flow control settings and prevents UART0 from being used. The UART0 modem control pins may be used as either TSIF 0 output or GPIO pins based on the TSPOMUX and UART0CTL settings. A TSSOMUX setting of ‘11’ overrides the RIN function with the TS1_WAITIN function. Table 3-33.

The DSPINT register shows the status of the ARM-to-DSP interrupts. The DSPINT register format is shown in Figure 3-20. Table 3-39 describes the register bit fields. The ARM may generate an interrupt to the DSP by setting one of the four INTDSP[3:0] bits or by setting the INTNMI bit in the DSPINTSET pseudo-register (see Figure 3-21). The interrupt set bit then self-clears and the corresponding INTDSP[3:0] or INTNMI bit in the DSPINT status register (see Figure 3-20) is automatically set to indicate that the interrupt was generated. After servicing the interrupt, the DSP clears the status bit by writing ‘1’ to the corresponding bit in the DSPINTCLR register (see Figure 3-22). The ARM may poll the status bit to determine when the DSP has completed the interrupt service. The DSP may generate an interrupt to the ARM in the same manner using the ARMINTSET and ARMINTCLR registers shown/described in Figure 3-24, Table 3-43, and Figure 3-25, Table 3-44, respectively. The DSP can then view the status of the DSP-to-ARM interrupts via the ARMINT register shown/described in Figure 3-23 and Table 3-42. 31 30 29 28 27 26 25 24 23 22 21 20 5 4 19 18 17 16 Reserved R-0000 0000 0000 0000 15 14 13 3 2 1 0 Reserved 12 11 10 9 INTNMI 8 7 6 Reserved INTDSP3 INTDSP2 INTDSP1 INTDSP0 R-0000 000 R-0 R-0000 R-0 R-0 R-0 R-0 LEGEND: R = Read only, n = Value at reset Figure 3-20.

While this assignment is purely a matter of software convention, during an emulation halt it is necessary for the device to know which peripherals are associated with the halting processor so that only those modules receive the suspend signal. This allows peripherals associated with the other (unhalted) processor to continue normal operation. The SUSPSRC register indicates the emulation suspend source for those peripherals which support emulation suspend. The SUSPSRC register format is shown in Figure 3-26. Brief details on the peripherals which correspond to the register bits are listed in Table 3-45. When the associated SUSPSRC bit is ‘0’, the peripheral’s emulation suspend signal is controlled by the ARM emulator and when set to ‘1’ it is controlled by the DSP emulator. 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 CRGEN1 SRC CRGEN0 SRC TIMR2 SRC TIMR1 SRC TIMR0 SRC GPIO SRC RSV PWM1 SRC PWM0 SRC SPI SRC UART2 SRC UART1 SRC UART0 SRC I2C SRC MCASP1 SRC MCASP0 SRC R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 12 3 15 13 11 10 9 8 7 6 5 4 RESERVED HPI SRC RSV EMAC SRC USB SRC VDCE SRC TSIF1 SRC TSIF0 SRC RSV VPIF SRC 0 RESERVED R-000 R/W-0 R-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R-0 R/W-0 R-0000 LEGEND: R/W = Read/Write; R = Read only; -n = value after reset Figure 3-26.

This may be achieved via pullup/pulldown resistors. The TMS320DM646x DMSoC 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 (listed in Table 2-6, Boot Terminal Functions), 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 DVDD 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 most systems, a 20-kΩ resistor can also be used as an external PU/PD on the pins that have IPUs/IPDs disabled and require an external PU/PD resistor while still meeting the above criteria. Users should confirm this resistor value is correct for their specific application.

As a good board design practice, such delays must always be taken into account.

TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839). If needed, external logic hardware such as buffers may be used to compensate any timing differences. For the DDR2 memory controller interface, it is not necessary to use the IBIS models to analyze timing characteristics. Section 6.10.2, DDR2 Interface, provides a PCB routing rules solution that describes the routing rules to ensure the DDR2 memory controller interface timings are met. 6.2 Recommended Clock and Control Signal Transition Behavior All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic manner. 142 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T Copyright © 2011, Texas Instruments Incorporated VCE6467T, AVCE6467T www.ti.com 6.3 SPRS690 – MARCH 2011 Power Supplies For more information regarding TI's power management products and suggested devices to power TI DSPs, visit www.ti.com/processorpower. 6.3.1 Power-Supply Sequencing The VCE6467T includes one core supply (CVDD), and two I/O supplies—DVDD33 and DVDDR2. To ensure proper device operation, a specific power-up sequence must be followed. Some TI power-supply devices include features that facilitate power sequencing—for example, Auto-Track and Slow-Start/Enable features. For more information on TI power supplies and their features, visit www.ti.com/processorpower. Here is a summary of the power sequencing requirements: • The power ramp order must be CVDD before DVDDR2, and DVDDR2 before DVDD33—meaning during power up, the voltage at the DVDDR2 rail should never exceed the voltage at the CVDD rail. Similarly, the voltage at the DVDDD33 rail should never exceed the voltage at the DVDDR2 rail. • From the time that power ramp begins, all power supplies (CVDD, DVDDR2, DVDD33) must be stable within 200 ms. The term "stable" means reaching the recommended operating condition (see Section 5.2, Recommended Operating Conditions table). 6.3.2 Power-Supply Design Considerations Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize inductance and resistance in the power delivery path. Additionally, when designing for high-performance applications utilizing the VCE6467T device, the PC board should include separate power planes for core, I/O, and ground; all bypassed with high-quality low-ESL/ESR capacitors. 6.3.3 Power-Supply Decoupling In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as possible close to the VCE6467T. These caps need to be close to the VCE6467T power pins, no more than 1.25 cm maximum distance to be effective. Physically smaller caps, such as 0402, are better but need to be evaluated from a yield/manufacturing point-of-view. Parasitic inductance limits the effectiveness of the decoupling capacitors, therefore physically smaller capacitors should be used while maintaining the largest available capacitance value. Larger caps for each supply can be placed further away for bulk decoupling. Large bulk caps (on the order of 100 μF) should be furthest away, but still as close as possible. Large caps for each supply should be placed outside of the BGA footprint. As with the selection of any component, verification of capacitor availability over the product's production lifetime should be considered. For more details on capacitor usage and placement, see the Implementing DDR2 PCB Layout on the TMS320DM646x DMSoC Application Report (literature number SPRAAM1A). 6.3.4 VCE6467T Power and Clock Domains The VCE6467T includes one single power domain — the "Always On" power domain. The "Always On" power domain is always on when the chip is on. The "Always On" domain is powered by the CVDD pins of the VCE6467T. All VCE6467T modules lie within the "Always On" power domain. Table 6-1 provides a listing of the VCE6467T clock domains. Two primary reference clocks are required for the VCE6467T device. These can either be crystal inputs or driven by external oscillators. A 33-MHz or 33.3-MHz crystal is recommended for the system PLLs, which generate the internal clocks for the ARM926, DSP, HDVICPs, peripherals, and the EDMA3. A 24- or 48-MHz crystal is also required if the USB (24-MHz only) or UART (either 24- or 48-MHz) peripherals are to be used. In addition, the 24- or 48-MHz input clock can be used to source the McASPs' clocks. For further description of the VCE6467T clock domains, see and Figure 6-4.

To achieve these quoted frequencines, the PLLC1 SYSCLKx (for SYSCLK4, SYSCLK5, SYSCLK6, SYSCLK8, SYSCLK9) default divider values must be changed based on the input crystal frequency. For the steps to change the PLLC1 SYSCLKx divider values, see theTMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). These domain clock sources, along with VP_CLKIN[3:0], STC_CLKIN, CRG0_VCXI, and CRG1_VCXI clock signals, go through the clock select logic to determine the clock source enabled as the input to the VPIF and TSIF peripherals.

The PSC consists of a Global PSC (GPSC) and a set of Local PSCs (LPSCs). The GPSC contains memory mapped registers, PSC interrupt control, and a state machine for each peripheral/module. An LPSC is associated with each peripheral/module and provides clock and reset control. The GPSC controls all of the VCE6467T's LPSCs. The ARM Subsystem does not have an LPSC module. ARM sleep mode is accomplished through the wait for interrupt instruction. The LPSCs for VCE6467T are shown in Table 6-3. The PSC Register memory map is given in Table 6-4. For more details on the PSC, see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). Table 6-3.

Any input crystal frequency between 27 MHz and 35 MHz can be used for the System Oscillator (DEV_MXI/DEV_CLKIN). The optimal external clock input frequency for the crystals are 33 MHz or 33.3 MHz for the system oscillator (DEV_MXI/DEV_CLKIN) and 24 MHz for the auxiliary oscillator. Section 6.4.1.1 provides more details on Option 1, using an on-chip oscillator with external crystal for the 33.3-MHz system oscillator. Section 6.4.1.2 provides more details on Option 1, using an on-chip oscillator with external crystal for the 24-MHz auxiliary oscillator. Section 6.4.2.1 provides details on Option 2, using an external 1.8-V LVCMOS-compatible clock input for the 33.3-MHz system oscillator. Section 6.4.2 provides details on Option 2, using an external 1.8-V LVCMOS-compatible clock input for the 24-MHz auxiliary oscillator. 6.4.1 Clock Input Option 1—Crystal 6.4.1.1 33.3-MHz for System Oscillator Clock Input Option 1—Crystal In this option, a crystal is used as the external clock input to the VCE6467T system oscillator. The 33.3-MHz oscillator provides the reference clock for all VCE6467T subsystems and peripherals. The on-chip oscillator requires an external 33.3-MHz crystal connected across the DEV_MXI and DEV_MXO pins, along with two load capacitors, as shown in Figure 6-7. The external crystal load capacitors must be connected only to the 33.3-MHz oscillator ground pin (DEV_VSS). Do not connect to board ground (VSS). The DEV_DVDD18 pin can be connected to the same 1.8 V power supply as DVDDR2.

PLL1 generates the frequencies required for the ARM, DSP, HDVICP0/1, EDMA, and peripherals. PLL2 generates the frequencies required for the DDR2 interface. Any input crystal frequency between 27 MHz and 35 MHz can be used for the System Oscillator (DEV_MXI/DEV_CLKIN). The recommended reference clock for both PLLs is the 33-MHz or 33.3-MHz crystal input. The VCE6467T has a third PLL that is embedded within the USB2.0 PHY and the 24-MHz oscillator is its reference clock source. This particular PLL is only usable for USB operation, and is discussed further in the TMS320DM646x DMSoC Universal Serial Bus (USB) Controller User's Guide (literature number SPRUER7). 6.5.1 PLL1 and PLL2 Both PLL1 and PLL2 power are supplied externally via the 1.8-V PLL power-supply pins (PLL1VDD18 and PLL2VDD18). An external EMI filter circuit must be added to PLL1VDD18 and PLL2VDD18, as shown in Figure 6-11. The 1.8-V supply of the EMI filters must be from the same 1.8-V power plane supplying the device’s 1.8-V I/O power-supply pins (DVDDR2). TI recommends EMI filter manufacturer Murata, part number NFM18CC222R1C3. All PLL external components (C1, C2, C3, C4, and the EMI Filters) must be placed as close to the device as possible. For the best performance, TI recommends that all the PLL external components be on a single side of the board without jumpers, switches, or components other than the ones shown in Figure 6-11. For reduced PLL jitter, maximize the spacing between switching signals and the PLL external components (C1, C2, C3, C4, and the EMI Filters).

PLL1 and PLL2 External Connection The minimum CLKIN rise and fall times should also be observed. For the input clock timing requirements, see Section 6.5.5, Clock PLL Electrical Data/Timing (Input and Output Clocks). There is an allowable range for PLL multiplier (PLLM). There is a minimum and maximum operating frequency for DEV_MXI/DEV_CLKIN, PLLOUT, AUX_MXI/AUX_CLKIN, and the device clocks (SYSCLKs). The PLL Controllers must be configured not to exceed any of these constraints documented in this section (certain combinations of external clock inputs, internal dividers, and PLL multiply ratios might not be supported). For these constraints (ranges), see Table 6-7 through .

Both PLL1 and PLL2 have stabilization, lock, and reset timing requirements that must be followed. The PLL stabilization time is the amount of time that must be allotted for the internal PLL regulators to become stable after the PLL is powered up (after the PLLCTL.PLLPWRDN bit goes through a 1-to-0 transition). The PLL should not be operated until this stabilization time has expired. This stabilization step must be applied after these resets—a Power-on Reset, a Warm Reset, or a Max Reset, as the PLLCTL.PLLPWRDN bit resets to a "1". For the PLL stabliziation time value, see Table 6-10. The PLL reset time is the amount of wait time needed for the PLL to properly reset (writing PLLRST = 1) before bringing the PLL out of reset (writing PLLRST = 0). For the PLL reset time value, see Table 6-10. The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 0 with PLLEN = 0) to when to when the PLL controller can be switched to PLL mode (PLLEN = 1). For the PLL lock time value, see Table 6-10. Table 6-10.

These data transfers include cache servicing, non-cacheable memory accesses, user-programmed data transfers, and host accesses. These are summarized as follows: • Transfer to/from on-chip memories – ARM926 TCM – DSP L1D memory – DSP L2 memory • Transfer to/from external storage – DDR2 SDRAM – NAND flash – Asynchronous EMIF (EMIFA) – ATA • Transfer to/from peripherals/hosts – VLYNQ – HPI – McASP0/1 – SPI – I2C – PWM0/1 – UART0/1/2 – PCI The EDMA supports two addressing modes: constant addressing and increment addressing. On the VCE6467T, constant addressing mode is not supported by any peripheral or internal memory. For more information on these two addressing modes, see the TMS320DM646x DMSoC Enhanced Direct Memory Access (EDMA) Controller User’s Guide (literature number SPRUEQ5). The VCE6467T device supports a programmable default burst size feature. The default burst size of each EDMA3 Transfer Controller (TC) is configured via the EDMA Transfer Controller Default Burst Size Configuration register (EDMATCCFG). For more detailed information on the EDMATCCFG register, see Section 3.6.2, Peripheral Selection After Device Reset. 6.6.1 EDMA3 Channel Synchronization Events The EDMA supports up to 64 EDMA channels which service peripheral devices and external memory. Table 6-15 lists the source of EDMA synchronization events associated with each of the programmable EDMA channels. For the VCE6467T device, the association of an event to a channel is fixed; each of the EDMA channels has one specific event associated with it. These specific events are captured in the EDMA event registers (ER, ERH) even if the events are disabled by the EDMA event enable registers (EER, EERH). For more detailed information on the EDMA module and how EDMA events are enabled, captured, processed, linked, chained, and cleared, etc., see the TMS320DM646x DMSoC Enhanced Direct Memory Access (EDMA) Controller User’s Guide (literature number SPRUEQ5) Table 6-15.

The VCE6467T device has several types of device-level global resets—power-on reset, warm reset, max reset, and system reset. Table 6-19 explains further the types of reset, the reset initiator, and the effects of each reset on the chip. See Section 6.7.9, Reset Electrical Data/Timing, for more information on the effects of each reset on the PLL controllers and their clocks. Table 6-19. Device-Level Global Reset Types TYPE INITIATOR POR pin EFFECT(S) Global chip reset (Cold reset). Activates the POR signal on chip, which resets the entire chip including the emulation logic. The power-on reset (POR) pin must be driven low during power ramp of the device. Device boot and configuration pins are latched. Power-on Reset (POR) Warm Reset RESET pin Resets everything except for the emulation logic. Emulator stays alive during Warm Reset. Device boot and configuration pins are latched. Max Reset Emulator, WD Timer (Timer 2) Same as a Warm Reset, except the VCE6467T device boot and configuration pins are not re-latched. System Reset Emulator A system reset maintains memory contents and does not reset the test and emulation circuitry. The device boot and configuration pins are also not re-latched. C64x+ Local Reset (DSP Reset) Software (register bit) MMR controls the C64x+ reset input. This is used for control of C64x+ reset by the ARM. The C64x+ Slave DMA port is still alive when in local reset. In addition to device-level global resets, the PSC provides the capability to cause local resets to peripherals and/or the C64x+ DSP. 6.7.1 Power-on Reset (POR Pin) Power-on Reset (POR) is initiated by the POR pin and is used to reset the entire chip, including the test and emulation logic. Power-on Reset is also referred to as a cold reset since the device usually goes through a power-up cycle. During power-up, the POR pin must be asserted (driven low) until the power supplies have reached their normal operating conditions. If an external oscillator is used on the DEV_MXI/DEV_CLKIN pin, the source clock should also be running at the correct frequency prior to de-asserting the POR pin. Note: A device power-up cycle is not required to initiate a Power-on Reset. The following sequence must be followed during a Power-on Reset. 1. Wait for the power supplies to reach normal operating conditions while keeping the POR pin asserted (driven low). 2. Wait for the input clock source to be stable while keeping the POR pin asserted (low). 3. Once the power supplies and the input clock source are stable, the POR pin must remain asserted (low) for a minimum of 12 DEV_MXI cycles. Within the low period of the POR pin, the following happens: – The reset signals flow to the entire chip (including the test and emulation logic), resetting the modules on chip. – The PLL Controller clocks start at the frequency of the DEV_MXI clock. The clocks are propagated throughout the chip to reset the chip synchronously. By default, both PLL1 and PLL2 are in reset and unlocked. The PLL Controllers default to PLL Bypass Mode. 4.

Both PLL Controllers are still in PLL Bypass Mode. Other device initialization also begins. 5. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At this point: – The I/O pins are controlled by the default peripherals (default peripherals are determined by PINMUX0 and PINMUX1 registers). – The clock and reset of each peripheral is determined by the default settings of the Power and Sleep Controller (PSC). – The PLL Controllers are operating in PLL Bypass Mode. – The ARM926 begins executing from the default address (either ARM boot ROM or EMIFA). After the reset sequence, the boot sequence begins. For more details on the boot sequence, see the Using the TMS320DM646x Bootloader Application Report (literature number SPRAAS0). 6.7.1.1 Usage of POR versus RESET Pins POR and RESET are independent resets. If the device needs to go through a power-up cycle, POR (not RESET) must be used to fully reset the device. In functional end-system, emulation/debugger logic is typically not needed; therefore, the recommendation for functional end-system is to use the POR pin for full device reset. If RESET pin is not needed, it can be pulled inactive (high) via an external pullup resistor. In a debug system, it is typically desirable to allow the reset of the device without crashing an emulation session. In this case, the user can use the POR pin to achieve full device reset and use the RESET pin to achieve a debug reset—which resets the entire device except test and emulation logic. 6.7.1.2 Latching Boot and Configuration Pins Internal to the chip, the two device reset pins RESET and POR are logically AND’ed together only for the purpose of latching device boot and configuration pins. The values on all device and boot configuration pins are latched into the BOOTCFG register when the logical AND of RESET and POR transitions from low to high. 6.7.2 Warm Reset (RESET Pin) A Warm Reset is activated by driving the RESET pin active-low. This resets everything in the device except the test or emulation logic. An emulator session will stay alive during warm reset. For more information on POR vs. RESET usage, see Section 6.7.1.1, Usage of POR versus RESET Pins and Section 6.7.1.2, Latching Boot and Configuration Pins. The following sequence must be followed during a Warm Reset: 1. Power supplies and input clock source should already be stable. 2. The RESET pin must be asserted (low) for a minimum of 12 DEV_MXI cycles. Within the low period of the RESET pin, the following happens: – The reset signals flow to the entire chip resetting all the modules on chip, except the test and emulation logic. – The PLL Controllers are reset thereby, switching back to PLL Bypass Mode and resetting all their registers to default values. Both PLL1 and PLL2 are placed in reset and lose lock. 3. The RESET pin may now be deasserted (driven high). When the RESET pin is deasserted (high), the configuration pin values are latched and the PLL Controllers changed their system clocks to their default divide-down values. Both PLL Controllers are still in PLL Bypass Mode. Other device initialization also begins. 184 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T Copyright © 2011, Texas Instruments Incorporated VCE6467T, AVCE6467T www.ti.com SPRS690 – MARCH 2011 4. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At this point: – The I/O pins are controlled by the default peripherals (default peripherals are determined by PINMUX0 and PINMUX1 registers). – The clock and reset of each peripheral is determined by the default settings of the Power and Sleep Controller (PSC). – The PLL Controllers are operating in PLL Bypass Mode. – The ARM926 begins executing from the default address (either ARM boot ROM, TCM RAM, or EMIFA). After the reset sequence, the boot sequence begins. For more details on the boot sequence, see the Using the TMS320DM646x Bootloader Application Report (literature number SPRAAS0). 6.7.3 Maximum Reset A Maximum (Max) Reset is initiated by the emulator or the watchdog timer (Timer 2). The effects are the same as a warm reset, except the device boot and configuration pins are not re-latched. The emulator initiates a maximum reset via the ICEPICK module. This ICEPICK-initiated reset is non-maskable. When the watchdog timer counter reaches zero, this will also initiate a maximum reset to recover from a runaway condition. To invoke the maximum reset via the ICEPICK module, the user can perform the following from the Code Composer Studio™ IDE menu: Debug→Advanced Resets→System Reset This is the Max Reset sequence: 1. Max Reset is initiated by the emulator or the watchdog timer. During this time, the following happens: – The reset signals flow to the entire chip, resetting all the modules on chip except the test and emulation logic. – The PLL Controllers are reset —thereby, switching back to PLL Bypass Mode and resetting all their registers to default values. Both PLL1 and PLL2 are placed in reset and lose lock. 2. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At this point: – The I/O pins are controlled by the default peripherals (default peripherals are determined by PINMUX0 and PINMUX1 registers). – The clock and reset of each peripheral is determined by the default settings of the Power and Sleep Controller (PSC). – The PLL Controllers are operating in PLL Bypass Mode. – The ARM926 begins executing from the default address (either ARM boot ROM, TCM RAM, or EMIFA). After the reset sequence, the boot sequence begins. Since the boot and configuration pins are not latched with a Max Reset, the previous values (as shown in the BOOTCFG register) are used to select the boot mode. For more details on the boot sequence, see the Using the TMS320DM646x Bootloader Application Report (literature number SPRAAS0). 6.7.4 System Reset A System Reset is initiated by the emulator. The following memory contents are maintained: • L1/L2 RAM: The C64x+ L1/L2 RAM content is retained. The L1/L2 cache content is not retained because tag information is reset. • DDR2 Memory Controller: The DDR2 Memory Controller registers are not reset. In addition, the DDR2 SDRAM memory content is retained if the user places the DDR2 SDRAM in self-refresh mode before invoking the System Reset.

The emulator initiates a System Reset via the C64x+ emulation logic. This reset can be masked by the emulator. This is the System Reset sequence: 1. The System Reset is initiated by the emulator. During this time, the following happens: – The reset signals flow to the entire chip resetting all the modules on chip, except the test and emulation logic. – The PLL Controllers are not reset. Internal system clocks are unaffected. If PLL1/PLL2 were locked before the System Reset, they remain locked. 2. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At this point: – The I/O pins are controlled by the default peripherals (default peripherals are determined by PINMUX0 and PINMUX1 registers). – The clock and reset of each peripheral (except the DDR2 Memory Controller) is determined by the default settings of the Power and Sleep Controller (PSC). – The DDR2 Memory Controller registers retain their previous values. Only the DDR2 Memory Controller state machines are reset by the System Reset. – The PLL Controllers are operating in the mode prior to System Reset. The System clocks are unaffected. – The ARM926 begins executing from the default address (either ARM boot ROM, TCM RAM, or EMIFA). After the reset sequence, the boot sequence begins. Since the boot and configuration pins are not latched with a System Reset, the previous values (as shown in the BOOTCFG register) are used to select the boot mode. For more details on the boot sequence, see the Using the TMS320DM646x Bootloader Application Report (literature number SPRAAS0). 6.7.5 C64x+ Local Reset (DSP Local Reset) With access to the PSC registers, the ARM can perform two types of DSP reset: DSP local reset and DSP module reset. When DSP local reset is asserted, the DSP’s internal memories (L1P, L1D, and L2) are still accessible. The local reset only resets the DSP CPU core, not the rest of the DSP subsystem, as the DSP module reset would. Local reset is useful when the DSP module is in the enable state or in the disable state. The DSP module reset takes precedence over local reset. The ARM uses local reset to reset the DSP to initiate the DSP boot process. The intent of module reset is to completely reset the DSP (like hard reset). For more detailed information on DSP local reset and DSP module reset, see the ARM-DSP Integration Chapter in the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). For information on peripheral selection at the rising edge of POR or RESET, see Section 3, Device Configurations of this data manual. 6.7.6 Peripheral Local Reset The user can configure the local reset and clock state of a peripheral through programming the PSC. Table 6-3, VCE6467T LPSC Assignments, identifies the LPSC numbers and the peripherals capable of being locally reset by the PSC. For more detailed information on the programming of these peripherals by the PSC, see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). 6.7.7 Reset Priority If any of the above reset sources occur simultaneously, the PLLC only processes the highest-priority reset request. The reset request priorities, from high to low, are as follows: • Power-on Reset 186 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T Copyright © 2011, Texas Instruments Incorporated VCE6467T, AVCE6467T www.ti.com • • • SPRS690 – MARCH 2011 Maximum Reset Warm Reset System Reset 6.7.7.1 Reset Type Status (RSTYPE) Register The Reset Type Status (RSTYPE) register (0x01C4 08E4) is the only register for the reset controller.

Pin Behaviors at Reset During normal operations, pins are controlled by the respective peripheral selected in the PINMUX0 or PINMUX1 register. During device level global reset, the pin behaves as follows: Multiplexed Boot and Configuration Pins These pins are forced 3-stated when the device is in reset. This is to ensure the proper boot and configuration values can be latched on these multiplexed pins. This is particularly useful in the case where the boot and configuration values are driven by an external control device. Once the device is out of reset, these pins are controlled by their respective default peripheral. • Boot and Configuration Pins Group: VP_DOUT6/DSPBOOT, VP_DOUT5/PCIEN, VP_DOUT4/CS2BW, VP_DOUT3/BTMODE3, VP_DOUT2/BTMODE2, VP_DOUT1/BTMODE1, and VP_DOUT0/BTMODE0.

Following RESET high or POR high, this signal group maintains the state the pins(s) achieved while RESET or POR was driven low until the peripheral is enabled via the PSC. For example, the DDR2 Z Group goes high impedance following RESET low or POR low and remains in the high-impedance state following RESET high or POR high until the DDR2 controller is enabled via the PSC.

Both the ARM and C64x+ are capable of servicing these interrupts. All of the device interrupts are routed to the ARM interrupt controller with only a limited set routed to the C64x+ interrupt controller. The interrupts can be selectively enabled or disabled in either of the controllers. In typical applications, the ARM handles most of the peripheral interrupts and grants control to the C64x+ for interrupts that are relevant to DSP algorithms. Also, the ARM and DSP can communicate with each other through interrupts. 6.8.1 ARM CPU Interrupts The ARM926 CPU core supports 2 direct interrupts: FIQ and IRQ. The VCE6467T ARM interrupt controller prioritizes up to 64 interrupt requests from various peripherals and subsystems, which are listed in Table 6-23, and interrupts the ARM CPU. Each interrupt is programmable for up to 8 levels of priority. There are 6 levels for IRQ and 2 levels for FIQ. Interrupts at the same priority level are serviced in order by the ARM Interrupt Number, with the lowest number having the highest priority. Table 6-24 shows the ARM interrupt controller registers and memory locations. For more details on ARM interrupt control, see the TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number SPRUEP9). 194 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T Copyright © 2011, Texas Instruments Incorporated VCE6467T, AVCE6467T www.ti.com SPRS690 – MARCH 2011 Table 6-23.

The DDR2 keep out region is defined for this purpose and is shown in Figure 6-29. The size of this region varies with the placement and DDR routing. Additional clearances required for the keep out region are shown in Table 6-35. DDR2 Controller A1 DDR2 Device A1 Figure 6-29. DDR2 Keepout Region NOTE The region shown in Figure 6-29 should encompass all the DDR2 circuitry and varies depending on placement. Non-DDR2 signals should not be routed on the DDR signal layers within the DDR2 keep out region. Non-DDR2 signals may be routed in the region provided they are routed on layers separated from DDR2 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.

The TSIF peripheral supports the following features: • 1-bit Serial and 8-bit Parallel independent receive and transmit interfaces with both synchronous and asynchronous modes. (TSIF1 supports Serial mode only.) • Stream input/output (I/O) speed rate configurable by the I/O clock speed • ATS (absolute time stamp) detection, correction, and addition modes • Automatically detects PAT and PMT and reflects assignment to the internal Packet Identification (PID) table (supported for partial Transfer Stream [TS] mode only; stream type and PID should be one-to-one mapping) • PID filter with 7 PID filter tables and stream type assignments • BYPASS mode implemented so that not only TS data, but any other data can be received or transmitted by the TSIF module • Ring buffer control for both writes (8 channels) and reads (1 channel) to/from memory • Supports “Specific Packet”, indicating boundary of plural program on TS • Supports Full-TS in only one mode–Semi-Automatic-A mode, allowing communication to the C64x+ CPU. • Supports Partial-TS in these modes–Semi-Automatic-B mode and Full-Automatic mode (provided stream type and PID are one-to-one mapping) For more detailed information on the CRGEN peripheral, see the TMS320DM646x DMSoC Clock Reference Generator User's Guide (literature number SPRUEQ1). 6.12.1 TSIF Bus Master The TSIF peripherals each include a bus master interface that accesses the DM646x system bus to transfer stream receive and transmit data.

Magnification ratio of horizontal resize and vertical resize can be configured separately (different value can be configured). • Anti-alias filter (combination of two kinds of low-pass filter) with horizontal 7 taps, and vertical direction. • Chrominance signal format conversion (CCV) on both directions, one is from 4:2:2 to 4:2:0 and one is from 4:2:0 to 4:2:2. This function also uses 4 taps interpolation. MPEG-1 specific format (half-pixel phased from even pixel position of luminance) is also supported. • Edge padding for preparation of MC with unrestricted motion vector (required by MPEG-4, H.264, VC-1). All modes (progressive, interlace frame, and interlace field) are supported (macro-block level control that is required in H.264 is not currently supported). • VC-1 range mapping in advanced profile (in case of displaying decoded reference image or trans-coding from VC-1 to any other format of video codec). • 2-bit hardware menu overlay with 256 steps of blending for each color. 6.14.1 VDCE Bus Master The VDCE includes a bus master interface that accesses the DM646x system bus to transfer data.

The PCI port interfaces to DSP internal resources via the data switched central resource. The data switched central resource is described in more detail in Section 4, System Interconnect. For more detailed information on the PCI port peripheral module, see the TMS320DM643x DMP Peripheral Component Interconnect (PCI) User's Guide (literature number SPRU985). 6.15.1 PCI Device-Specific Information The PCI peripheral on the VCE6467T DMSoC conforms to the PCI Local Bus Specification Revision 2.3. The PCI peripheral can act both as a PCI bus master and as a target. It supports PCI bus operation of speeds up to 66 MHz and uses a 32-bit data/address bus. On the VCE6467T device, the pins of the PCI peripheral are multiplexed with the pins of the EMIFA, GPIO, HPI, and ATA peripherals. For more detailed information on how to select PCI, see Section 3, Device Configurations. The VCE6467T device provides an initialization mechanism through which the default values for some of the PCI configuration registers can be read from an I2C EEPROM. Table 6-60 shows the registers which can be initialized through the PCI auto-initialization. The default value of these registers when PCI auto-initialization is not used. PCI auto-initialization is enabled by selecting PCI boot with auto-initialization. For information on how to select PCI boot with auto-initialization, see Section 3.4.1, Boot Modes. For more information on PCI auto-initialization, see the TMS320DM646x DMSoC Peripheral Component Interconnect (PCI) User's Guide (literature number SPRUER2) and the Using the TMIS320DM646x Bootloader Application Report (literature number SPRAAS0). The PCI peripheral is a master peripheral within the VCE6467T DMSoC. Table 6-60.

Therefore, the AC timing specifications are not reproduced here. For more information on the AC timing specifications, see Section 4.2.3, Timing Specification (66-MHz timing) of the PCI Local Bus Specification Revision 2.3. Note: The VCE6467T PCI peripheral only supports 3.3-V signaling and up to 66-MHz operation.

The EMAC supports 10Base-T (10 Mbits/second [Mbps]), and 100BaseTX (100 Mbps), in either half- or full-duplex mode, and 1000BaseT (1000 Mbps) in full-duplex mode, with hardware flow control and quality-of-service (QOS) support. The EMAC controls the flow of packet data from the VCE6467T device to the PHY. The MDIO module controls the PHY configuration and status monitoring. The EMAC module conforms to the IEEE 802.3-2002 standard, describing the “Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Access Method and Physical Layer” specifications. The IEEE 802.3 standard has also been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E). Deviating from this standard, the EMAC module does not use the Transmit Coding Error signal MTXER. Instead of driving the error pin when an underflow condition occurs on a transmitted frame, the EMAC will intentionally generate an incorrect checksum by inverting the frame CRC, so that the transmitted frame will be detected as an error by the network. In addition, the EMAC I/Os operate at 3.3 V and are not compatible with 2.5-V I/O signaling. Therefore, only Ethernet PHYs with 3.3-V I/O interface should be used. Both the EMAC and MDIO modules interface to the VCE6467T device through a custom interface that allows efficient data transmission and reception. This custom interface is referred to as the EMAC control module. The EMAC control module contains the necessary components to allow the EMAC to make efficient use of device memory, plus it controls device interrupts. The EMAC control module incorporates 8K bytes of internal RAM to hold EMAC buffer descriptors. For more detailed information on the EMAC, see the TMS320DM646x DMSoC Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO) Module User's Guide (literature number SPRUEQ6). 6.16.1 EMAC Device-Specific Information The EMAC module on the VCE6467T supports two interface modes: Media Independent Interface (MII) and Gigabit Media Independent Interface (GMII). The MII and GMII interface modes are defined in the IEEE 802.3-2002 standard. The VCE6467T EMAC uses the same pins for the MII and GMII modes of operation. Only one mode can be used at a time. The mode used is selected at device reset based on the GMIIEN bit in the MACCONTROL register. For more detailed information on the EMAC GMIIEN bit, see the TMS320DM646x DMSoC Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO) Module User's Guide (literature number SPRUEQ6). The MII and GMII modes-of-operation pins are as follows: • MII: MTCLK, MRCLK, MTXD[3:0], MRXD[3:0], MTXEN, MRXDV, MRXER, MCOL, MCRS, MDCLK, and MDIO. • GMII: RFTCLK, GMTCLK, MTCLK, MRCLK, MTXD[7:0], MRXD[7:0], MTXEN, MRXDV, MRXER, MCOL, MCRS, MDCLK, and MDIO. 250 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T Copyright © 2011, Texas Instruments Incorporated VCE6467T, AVCE6467T www.ti.com SPRS690 – MARCH 2011 6.16.2 EMAC Bus Master Memory Map The EMAC control module includes a multi-channel DMA engine which is used to transfer receive and transmit packets between the EMAC and VCE6467T memory.

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. For more detailed information on the MDIO peripheral, see the TMS320DM646x DMSoC Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO) Module User's Guide (literature number SPRUEQ6) .

The host device functions as a master to the interface, which increases ease of access. The host and CPU can exchange information via internal or external memory. The host also has direct access to memory-mapped peripherals. Connectivity to the CPU memory space is provided through the EDMA3 controller. 6.18.1 HPI Device-Specific Information The VCE6467T device includes a user-configurable 32- or 16-bit Host-port interface (HPI32/HPI16). • Multiplexed (address/data) operation • Configurable single full-word cycle and dual half-word cycle access modes • Bursting available utilizing 8-word read and write FIFOs • HPIA register supports auto-incrementing • HPID register/FIFOs providing data-path between external host interface and system bus • Multiple strobes and control signals to allow flexible host connection • Configurable asynchronous HRDY output to allow HPI to insert wait states to the Host [System Module Register HPICTL.HRDYMODE] • Software control of data prefetching to the HPID/FIFOs • DMSoC-to-Host interrupt output signal controlled by HPIC accesses • Host-to-DMSoC interrupt controlled by HPIC accesses NOTE: The VCE6467T HPI does not support the HAS feature. For proper HPI operation if the HAS pin (D4) is routed out, the HAS pin must be pulled up via an external resistor. The VCE6467T HPICTL register (0x01C4 0030) is part of the System Module Registers. The HPICTL register controls write access to the HPI peripheral control and address registers as well as determines the host time-out value. The HPICTL System Module Register also determines the operation of the HRDY output which allows the HPI to insert wait states to the Host. For more detailed information on the HPICTL System Module Register, see Section 3.6.2, Peripheral Selection After Device Reset. For more detailed information on the HPI peripheral, see the TMS320DM646x DMSoC Host Port Interface (HPI) User's Guide (literature number SPRUES1). 6.18.2 HPI Bus Master The HPI peripheral includes a bus master interface that allows external device initiated transfers to access the VCE6467T system bus.

The ARM/C64x+ 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 ARM/C64x+ can access HPIAW and HPIAR independently. For more details about the HPIA registers and their modes, see the TMS320DM646x DMSoC Host Port Interface (HPI) User's Guide (literature number SPRUES1).

The McASP is useful for time-division multiplexed (TDM) stream, Inter-Integrated Sound (I2S) protocols, and intercomponent digital audio interface transmission (DIT). 6.22.1 McASP Device-Specific Information The VCE6467T device includes two multichannel audio serial port (McASP) interface peripherals (McASP0 and McASP1). The McASP0 module consists of a transmit and receive section. These sections can operate completely independently with different data formats, separate master clocks, bit clocks, and frame syncs or alternatively, the transmit and receive sections may be synchronized. The McASP0 module also includes a pool of 4 shift registers that may be configured to operate as either transmit data or receive data. The transmit section of the McASP0 can transmit data in either a time-division-multiplexed (TDM) synchronous serial format or in a digital audio interface (DIT) format where the bit stream is encoded for S/PDIF, AES-3, IEC-60958, CP-430 transmission. The receive section of the McASP0 peripheral supports the TDM synchronous serial format. The McASP0 module can support one transmit data format (either a TDM format or DIT format) and one receive format at a time. All transmit shift registers use the same format and all receive shift registers use the same format. However, the transmit and receive formats need not be the same. Both the transmit and receive sections of the McASP also support burst mode which is useful for non-audio data (for example, passing control information between two DSPs). The McASP0 peripheral has additional capability detection/handling, as well as error management. for flexible clock generation, and error The VCE6467T McASP1 module is a reduced feature version of the McASP peripheral. The McASP1 module provides a single transmit-only shift register and can transmit data in DIT format only. For more detailed information on and the functionality of the McASP peripheral, see the TMS320DM646x DMSoC Multichannel Audio Serial Port (McASP) User's Guide (literature number SPRUER1). 300 Peripheral Information and Electrical Specifications Submit Documentation Feedback Product Folder Link(s): VCE6467T AVCE6467T Copyright © 2011, Texas Instruments Incorporated VCE6467T, AVCE6467T www.ti.com 6.22.2 SPRS690 – MARCH 2011 McASP0 and McASP1 Peripheral Register Description(s) Table 6-101.

The SPI is normally used for communication between the TMS320DM646x DMSoC and external peripherals. Typical applications inlcude a interface to external I/O or peripheral expansion via devices such as shift regisers, display drivers, SPI EEPROMs, and Analog-to-Digital Converters (ADCs). 6.23.1 SPI Device-Specific Information The VCE6467T SPI supports the following features: • Master/slave operation • 2 chip selects for interfacing/control to multiple SPI slave devices • 3-, 4-, 5-wire interface [The VCE6467T supports 3-pin mode, 2 4-pin modes, and the 5-pin mode.] • 16-bit shift register • Receive buffer register • 8-bit clock prescaler • Programmable SPI clock frequency range, character length, and clock phase and polarity 6.23.2 SPI Peripheral Register Description(s) Table 6-109 shows the SPI registers.

These pins could potentially draw current when the device is powered down. A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus system, but the requirement tsu(SDA-SCLH)≥ 250 ns must then be met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line tr max + tsu(SDA-SCLH)= 1000 + 250 = 1250 ns (according to the Standard-mode I2C-Bus Specification) before the SCL line is released. A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the undefined region of the falling edge of SCL. The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal. Cb = total capacitance of one bus line in pF.

The GP timer mode can be used to generate periodic interrupts or EDMA synchronization events. The watchdog timer mode is used to provide a recovery mechanism for the device in the event of a fault condition, such as a non-exiting code loop. 6.27.1 Timers Device-Specific Information The VCE6467T device has 3 64-bit general-purpose timers which have the following features: • 64-bit count-up counter • Timer modes: – 64-bit general-purpose timer mode (Timer 0 and 1) – Dual 32-bit general-purpose timer mode (Timer 0 and 1) – Watchdog timer mode (Timer 2) [mainly controlled by the ARM] • 2 possible clock sources: – Internal clock – External clock input via timer input pin TINP0U, TINP0L, and TINP1L, (Timer 0 and 1 only) • 2 operation modes: – One-time operation (timer runs for one period then stops) – Continuous operation (timer automatically resets after each period) • Generates interrupts to the DSP and the ARM CPUs • Generates sync event to EDMA • Causes device global reset upon watchdog timer timeout (Timer 2 only) For more detailed information, see the TMS320DM646x DMSoC 64-Bit Timer User's Guide (literature number SPRUER5). 6.27.2 Timer Peripheral Register Description(s) Table 6-139, Table 6-140, and Table 6-141 show the registers for Timer 0, Timer 1, and Timer 2 (Watchdog).

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 GP[0:15]). 6.28.1 GPIO Device-Specific Information The VCE6467T GPIO peripheral supports the following: • Up to 33 3.3-V GPIO pins, GP[0:47; not all pinned out] • Interrupts: – Up to 8 unique GP[0:7] interrupts from Bank 0 – 3 GPIO bank (aggregated) interrupt signals from each of the 3 banks of GPIOs – Interrupts can be triggered by rising and/or falling edge, specified for each interrupt capable GPIO signal • DMA events: – Up to 8 unique GPIO DMA events from Bank 0 – 3 GPIO bank (aggregated) DMA event signals from each of the 3 banks of GPIOs • Set/clear functionality: Software writes 1 to corresponding bit position(s) to set or to clear GPIO signal(s). This allows multiple software 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 software, 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. Although, the VCE6467T device implements three GPIO banks, not all GPIOs from all banks are available externally (pinned out). The following GPIOs are not pinned out on the VCE6467T device: • BANK 0 – GP[9] – GP[14] – GP[15] • BANK 1 – GP[27:31] • BANK 2 • GP[34] • GP[35] • GP[43:47] For more detailed information on GPIOs, see the TMS320DM646x DMSoC General-Purpose Input/Output (GPIO) User's Guide (literature number SPRUEQ8).

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. 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. VCE6467T 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. 6.29.1 JTAG ID (JTAGID) Register Description(s) Table 6-147.
