The TMS320C64x+™ DSPs (including the TMS320DM6433 device) are the highest-performancefixed-point DSP generation in the TMS320C6000™ DSP platform. The DM6433 device is based on thethird-generation high-performance, advanced VelociTI™ very-long-instruction-word (VLIW) architecturedeveloped by Texas Instruments (TI), making these DSPs an excellent choice for digital mediaapplications. The C64x+™ devices are upward code-compatible from previous devices that are part of theC6000™ DSP platform. The C64x™ DSPs support added functionality and have an expanded instructionset from previous devices.
Any reference to the C64x DSP or C64x CPU also applies, unless otherwise noted, to the C64x+ DSP andC64x+ CPU, respectively.
With performance of up to 5600 million instructions per second (MIPS) at a clock rate of 700 MHz, theC64x+ core offers solutions to high-performance DSP programming challenges. The DSP core possessesthe operational flexibility of high-speed controllers and the numerical capability of array processors. TheC64x+ DSP core processor has 64 general-purpose registers of 32-bit word length and eight highlyindependent functional units—two multipliers for a 32-bit result and six arithmetic logic units (ALUs). Theeight 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 2800 millionMACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 5600 MMACS. For more detailson the C64x+ DSP, see the TMS320C64x/C64x+ DSP CPU and Instruction Set Reference Guide(literature number SPRU732 ).
The DM6433 also has application-specific hardware logic, on-chip memory, and additional on-chipperipherals similar to the other C6000 DSP platform devices. The DM6433 core uses a two-levelcache-based architecture. The Level 1 program memory/cache (L1P) consists of a 256K-bit memoryspace that can be configured as mapped memory or direct mapped cache, and the Level 1 data (L1D)consists of a 640K-bit memory space —384K-bit of which is mapped memory and 256K-bit of which canbe configured as mapped memory or 2-way set-associative cache. The Level 2 memory/cache (L2)consists of a 1M-bit memory space that is shared between program and data space. L2 memory can beconfigured as mapped memory, cache, or combinations of the two.

The peripheral set includes: 1 configurable video port; a 10/100 Mb/s Ethernet MAC (EMAC) with amanagement data input/output (MDIO) module; a 4-bit transmit, 4-bit receive VLYNQ interface; aninter-integrated circuit (I2C) Bus interface; a multichannel buffered serial port (McBSP0); a multichannelaudio serial port (McASP0) with 4 serializers; 2 64-bit general-purpose timers each configurable as2 independent 32-bit timers; 1 64-bit watchdog timer; a user-configurable 16-bit host-port interface (HPI);up to 111-pins of general-purpose input/output (GPIO) with programmable interrupt/event generationmodes, multiplexed with other peripherals; a UART with hardware handshaking support; 3 pulse widthmodulator (PWM) peripherals; 1 peripheral component interconnect (PCI) [33 MHz]; and 2 gluelessexternal memory interfaces: an asynchronous external memory interface (EMIFA) for slowermemories/peripherals, and a higher speed synchronous memory interface for DDR2.
The DM6433 device includes a Video Processing Subsystem (VPSS) with a Video Processing Back-End(VPBE) output.
The Video Processing Back-End (VPBE) is comprised of an On-Screen Display Engine (OSD) and aVideo Encoder (VENC). The OSD engine is capable of handling 2 separate video windows and 2 separateOSD windows. Other configurations include 2 video windows, 1 OSD window, and 1 attribute windowallowing up to 8 levels of alpha blending. The VENC provides four analog DACs that run at 54 MHz,providing a means for composite NTSC/PAL video, S-Video, and/or Component video output. The VENCalso provides up to 24 bits of digital output to interface to RGB888 devices. The digital output is capable of8/16-bit BT.656 output and/or CCIR.601 with separate horizontal and vertical syncs.
The Resizer accepts image data for separate horizontal and vertical resizing from 1/4x to 4x in incrementsof 256/N, where N is between 64 and 1024.
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the DM6433 andthe network. The DM6433 EMAC support both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps)and 100 Mbps in either half- or full-duplex mode, with hardware flow control and quality of service (QOS)support.
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order toenumerate all PHY devices in the system.
The I2C and VLYNQ ports allow DM6433 to easily control peripheral devices and/or communicate withhost processors.
The rich peripheral set provides the ability to control external peripheral devices and communicate withexternal processors. For details on each of the peripherals, see the related sections later in this documentand the associated peripheral reference guides.
The DM6433 has a complete set of development tools. These include C compilers, a DSP assemblyoptimizer to simplify programming and scheduling, and a Windows™ debugger interface for visibility intosource code execution.

The C64x+ Central Processing Unit (CPU) consists of eight functional units, two register files, and twodata paths as shown in Figure 2-1 . The two general-purpose register files (A and B) each contain32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can bedata address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bitdata, 40-bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values arestored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or32 MSBs in the next upper register (which is always an odd-numbered register).
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing oneinstruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L unitsperform a general set of arithmetic, logical, and branch functions. The .D units primarily load data frommemory to the register file and store results from the register file into memory.
The 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 x32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies withadd/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support forGalois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs andmodems require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputsand produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with roundingcapability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The32 x 32 bit multiply instructions provide the extended precision necessary for audio and otherhigh-precision algorithms on a variety of signed and unsigned 32-bit data types.
The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on apair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit dataperforming dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.
The C64x+ core enhances the .S unit in several ways. In the C64x core, dual 16-bit MIN2 and MAX2comparisons were only available on the .L units. On the C64x+ core they are also available on the .S unitwhich increases the performance of algorithms that do searching and sorting. Finally, to increase datapacking and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bitand dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Packinstructions return parallel results to output precision including saturation support.
Other new features include:•SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops wheremultiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code sizeassociated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.•Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many commoninstructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C64x+compiler can restrict the code to use certain registers in the register file. This compression isperformed by the code generation tools.
•Instruction Set Enhancement - As noted above, there are new instructions such as 32-bitmultiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois fieldmultiplication.

•Exceptions Handling - Intended to aid the programmer in isolating bugs. The C64x+ CPU is able todetect and respond to exceptions, both from internally detected sources (such as illegal op-codes) andfrom system events (such as a watchdog time expiration).•Privilege - Defines user and supervisor modes of operation, allowing the operating system to give abasic level of protection to sensitive resources. Local memory is divided into multiple pages, each withread, write, and execute permissions.•Time-Stamp Counter - Primarily targeted for Real-Time Operating System (RTOS) robustness, afree-running time-stamp counter is implemented in the CPU which is not sensitive to system stalls.

The C64x+ core uses a two-level cache-based architecture. The Level 1 Program memory/cache (L1P)consists of 32 KB memory space that can be configured as mapped memory or direct mapped cache. TheLevel 1 Data memory/cache (L1D) consists of 80 KB—48 KB of which is mapped memory and 32 KB ofwhich can be configured as mapped memory or 2-way set associated cache. The Level 2 memory/cache(L2) consists of a 128 KB memory space that is shared between program and data space. L2 memory canbe configured as mapped memory, cache, or a combination of both.
Table 2-2 shows a memory map of the C64x+ CPU cache registers for the device.

(1) For all bootmodes that default to DSPBOOTADDR = 0x0010 0000 (i.e., all boot modes except the EMIFA ROM Direct Boot,BOOTMODE[3:0] = 0100, FASTBOOT = 0), the bootloader code disables all C64x+ cache (L2, L1P, and L1D) so that upon exit from thebootloader code, all C64x+ memories are configured as all RAM (L2CFG.L2MODE = 0h, L1PCFG.L1PMODE = 0h, andL1DCFG.L1DMODE = 0h). If cache use is required, the application code must explicitly enable the cache. For more information on bootmodes, see Section 3.4.1 ,Boot Modes. For more information on the bootloader, see the Using the TMS320DM643x BootloaderApplication Report (literature number SPRAAG0 ). For the EMIFA ROM Direct Boot (BOOTMODE[3:0] = 0100, FASTBOOT = 0), thebootloader is not executed—that is, L2 RAM/Cache defaults to all RAM (L2CFG.L2MODE = 0h); L1P RAM/Cache defaults to all cache(L1PCFG.L1PMODE = 7h); and L1D RAM/Cache defaults to all cache (L1DCFG.L1DMODE = 7h).(2) The EMIFA CS0 and CS1 are not functionally supported on the DM6433 device, and therefore, are not pinned out.

Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions inthe smallest possible package. Pin multiplexing is controlled using a combination of hardwareconfiguration at device reset and software programmable register settings. For more information on pinmuxing, see TBD, Multiplexed Pin Configurations of this document.

2.6 Terminal Functions
TMS320DM6433
Digital Media Processor
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
www.ti.com
The terminal functions tables (Table 2-5 through Table 2-31 ) identify the external signal names, theassociated pin (ball) numbers along with the mechanical package designator, the pin type, whether the pinhas any internal pullup or pulldown resistors, and a functional pin description. For more detailedinformation on device configuration, peripheral selection, multiplexed/shared pin, and debuggingconsiderations, see the Device Configurations section of this data manual.
All device boot and configuration pins (except PCIEN) are multiplexed configuration pins— meaning theyare multiplexed with functional pins. These pins function as device boot and configuration pins only duringdevice reset. The input states of these pins are sampled and latched into the BOOTCFG register whendevice reset is deasserted (see Note below). After device reset is deasserted, the values on thesemultiplexed pins no longer have to hold the configuration.
The PCIEN pin is a standalone configuration pin. Its value is latched into the BOOTCFG register whendevice reset is deasserted (see Note below). Unlike the multiplexed device boot and configuration pins,the value on the PCIEN pin even after device reset is deasserted must hold the configuration.
For proper device operation, external pullup/pulldown resistors may be required on these device boot andconfiguration pins. Section 3.9.1 ,Pullup/Pulldown Resistors discusses situations where externalpullup/pulldown resistors are required.
Note: Internal to the chip, the two device reset pins RESET and POR are logically AND’d together for thepurpose of latching device boot and configuration pins. The values on all device boot and configurationpins are latched into the BOOTCFG register when the logical AND of RESET and POR transitions fromlow-to-high.

Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standardproduction devices. Texas Instruments recommends that these devices not be used in any productionsystem because their expected end-use failure rate still is undefined. Only qualified production devices areto be used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates thepackage type (for example, ZWT), the temperature range (for example, "Blank" is the commercialtemperature range), and the device speed range in megahertz (for example, "6" indicates [600-MHz]).

3.2 Power Considerations
TMS320DM6433
Digital Media Processor
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008

The DM6433 provides several means of managing power consumption.
As described in the Section 6.3.4 ,DM6433 Power and Clock Domains, the DM6433 has one single powerdomain—the “Always On” power domain. Within this power domain, the DM6433 utilizes local clock gatingvia the Power and Sleep Controller (PSC) to achieve power savings. For more details on the PSC, seeSection 6.3.5 ,Power and Sleep Controller (PSC) and the TMS320DM643x DMP DSP SubsystemReference Guide (literature number SPRU978 ).
Some of the DM6433 peripherals support additional power saving features. For more details on powersaving features supported, see the peripheral-specific reference guides [listed/linked in theTMS320DM643x DMP Peripherals Overview Reference Guide (literature number SPRU983 ).
Most DM6433 3.3-V I/Os can be powered-down to reduce power consumption. The VDD3P3V_PWDNregister in the System Module (see Figure 3-1 ) is used to selectively power down unused 3.3-V I/O pins.For independent control, the 3.3-V I/Os are separated into functional groups—most of which are namedaccording to the pin multiplexing groups (see Table 3-2 ). For these I/O groups, only the I/O buffers neededfor Host/EMIFA Boot or Power-Up Operations are powered up by default (CLKOUT Block, EMIFA/VPSSBlock, Host Block, PCI Data Block, and GPIO Block).
Note: To save power, all other I/O buffers are powered down by default. Before using these pins, the usermust 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, seeSection 3.7.3.1 ,Multiplexed Pins on DM6433.
Note: The VDD3P3V_PWDN register only controls the power to the I/O buffers. The Power and SleepController (PSC) determines the clock/power state of the peripheral.31 16

Global device and local peripheral clocks are controlled by the PLL Controllers (PLLC1 and PLLC2) andthe Power and Sleep Controller (PSC). In addition, the System Module VPSS_CLKCTL register configuresthe clock source to the Video Processing Subsystem (VPSS).
After device reset, the user is responsible for programming the PLL Controllers (PLLC1 and PLLC2) andthe Power and Sleep Controller (PSC) to bring the device up to the desired clock frequency and thedesired peripheral clock state (clock gating or not).
For additional power savings, some of the DM6433 peripherals support clock gating within the peripheralboundary. For more details on clock gating and power saving features supported by a specific peripheral,see the peripheral-specific reference guides [listed/linked in the TMS320DM643x DMP PeripheralsOverview Reference Guide (literature number SPRU983 )].
The DM6433 defaults to PLL bypass mode. To bring the device up to the desired clock frequency, theuser should program PLLC1 and PLLC2 after device reset.
DM6433 supports a FASTBOOT option, where upon exit from device reset the internal bootloader codeautomatically programs the PLLC1 into PLL mode with a specific PLL multiplier and divider to speed updevice boot. While the FASTBOOT option is beneficial for faster boot, the PLL multiplier and dividerselected for boot may not be the exact frequency desired for the run-time application. It is the user'sresponsibility to reconfigure PLLC1 after fastboot to bring the device into the desired clock frequency.Section 3.4.1 ,Boot Modes discusses the different fast boot modes in more detail.
The user must adhere to the various clock requirements when programming the PLLC1 and PLLC2:•Fixed frequency ratio requirements between CLKDIV1, CLKDIV3, and CLKDIV6 clock domains. Formore details on the frequency ratio requirements, see Section 6.3.4 ,DM6433 Power and ClockDomains.

SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The boot sequence is a process by which the device's memory is loaded with program and data sections,and by which some of the device's internal registers are programmed with predetermined values. The bootsequence is started automatically after each device-level global reset. For more details on device-levelglobal resets, see Section 6.5 ,Reset.
There are several methods by which the memory and register initialization can take place. Each of thesemethods is referred to as a boot mode. The boot mode to be used is selected at reset. For moreinformation 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, andsecondary user bootloaders from peripherals or external memories. Boot modes, pin configurations, andregister configurations required for booting the device, are described in the following subsections.
The DM6433 boot modes are determined by these device boot and configuration pins. For information onhow these pins are sampled at device reset, see Section 6.5.1.2 ,Latching Boot and Configuration Pins.•BOOTMODE[3:0]

BOOTMODE[3:0] and PCIEN determine the type of boot (e.g., I2C Boot, EMIFA Boot, HPI Boot, or PCIBoot, etc.). FASTBOOT determines if the PLL is enabled during boot to speed up the boot process.
The combination of AEM[2:0] and PLLMS[2:0] is used by bootloader code to determine the PLL multiplierused during fastboot modes (FASTBOOT = 1).
The DM6433 boot modes are grouped into three categories—Non-Fastboot Modes, Fixed-MultiplierFastboot Modes, and User-Select Multiplier Fastboot Modes.
•Non-Fastboot Modes (FASTBOOT = 0): The device operates in default PLL bypass mode duringboot. The Non-Fastboot bootmodes available on the DM6433 are shown in Table 3-5 .•Fixed-Multiplier Fastboot Modes (FASTBOOT = 1, AEM[2:0] = 001b): The bootloader code speedsup the device during boot according to the fixed PLL multipliers. The Fixed-Multiplier Fastbootbootmodes available on the DM6433 are shown in Table 3-6 .Note: The PLLMS[2:0] configurations have no effect on the Fixed-Multiplier Fastboot Modes, as thesepins function as AEAW[2:0] to select the EMIFA address width when AEM[2:0] = 001b.•User-Select Multiplier Fastboot Modes (FASTBOOT = 1, AEM[2:0] = 000b,011b,100b,101b): Thebootloader code speeds up the device during boot. The PLL multiplier is selected by the user via thePLLMS[2:0] pins. The User-Select Multiplier Fastboot bootmodes available on the DM6433 are shownin Table 3-7 .

Digital Media Processor

SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
As shown in Table 3-5 ,Table 3-6 , and Table 3-7 , at device reset the Boot Controller defaults theDSPBOOTADDR to one of two values based on the boot mode selected. In all boot modes, the C64x+ isimmediately released from reset and begins executing from address location indicated inDSPBOOTADDR.
•Internal Bootloader ROM (0x0010 0000): For most boot modes, the DSPBOOTADDR defaults to theinternal Bootloader ROM so that the DSP can immediately execute the bootloader code in the internalROM. The bootloader code decodes the captured BOOTMODE, FASTBOOT, PCIEN, default AEM(DAEM), and PLLMS information (in the BOOTCFG register) to determine the proper boot operation.Note: For all boot modes that default to DSPBOOTADDR = 0x0010 0000, the bootloader codedisables all C64x+ cache (L2, L1P, and L1D) so that upon exit from the bootloader code, all C64x+memories are configured as all RAM. If cache use is required, the application code must explicitlyenable the cache. For more information on boot modes, see Section 3.4.1 ,Boot Modes. For moreinformation on the bootloader, see the Using the TMS320DM643x Bootloader Application Report(literature number SPRAAG0 ).•EMIFA Chip Select Space 2 (0x4200 0000): The EMIFA ROM Direct Boot in PLL Bypass Mode(BOOTCFG settings BOOTMODE[3:0] = 0100b, FASTBOOT = 0) is the only exception where theDSPBOOTADDR defaults to the EMIFA Chip Select Space 2. The DSP begins execution directly fromthe external ROM at this EMIFA space.
For more information how the bootloader code handles each boot mode, see Using the TMS320DM643xBootloader Application Report (literature number SPRAAG0 ).
When DM6433 exits pin reset ( RESET or POR released), the PLL Controllers (PLLC1 and PLLC2) defaultto PLL Bypass Mode. This means the PLLs are disabled, and the MXI/CLKIN clock input is driving thechip. All the clock domain divider ratios discussed in Section 6.3.4 ,DM6433 Power and Clock Domains,still apply. For example, assume an MXI/CLKIN frequency of 27 MHz—meaning the internal clock sourcefor EMIFA is at CLKDIV3 domain = 27 MHz/3 = 9 MHz, a very slow clock. In addition, the EMIFA registersare reset to the slowest configuration which translates to very slow peripheral operation/boot.
To optimize boot time, the user should reprogram clock settings via the PLLC as early as possible duringthe boot process. The FASTBOOT pin facilitates this operation by allowing the device to boot at a fasterclock rate.
Except for the EMIFA ROM Direct Boot in PLL Bypass Mode (BOOTCFG settings BOOTMODE[3:0] =0100b, FASTBOOT = 0), all other boot modes default to executing from the Internal Bootloader ROM. Thefirst action that the bootloader code takes is to decode the boot mode. If the FASTBOOT option isselected (BOOTCFG.FASTBOOT = 1), the bootloader software begins by programming the PLLC1(System PLLC) to PLL Mode to give the device a slightly faster operation before fetching code fromexternal devices. The exact PLL multiplier that the bootloader uses is determined by the AEM[2:0] andPLLMS[2:0] settings, as shown in Table 3-6 and Table 3-7 .
Some boot modes must be accompanied with FASTBOOT = 1 so that the corresponding peripheral canrun at a reasonable rate to communicate to the external device(s). This includes PCI boot.
Note: PLLC2 still stays in PLL Bypass Mode, the bootloader does not reconfigure it.

Table 3-6 ,Table 3-7 , and Table 3-8 show the PLL multipliers used by the bootloader code during fastboot(FASTBOOT = 1) and the resulting device frequency. The user is responsible for selecting the bootmodewith the appropriate PLL multiplier for their MXI/CLKIN clock source so that the device speed and PLLfrequency range requirements are met. For the PLLC1 Clock Frequency Ranges, see Table 6-15 ,PLLC1Clock Frequency Ranges in Section 6.7.1 ,PLL1 and PLL2.
The following are guidelines for PLL output frequency and device speed (frequency):•PLL Output Frequency: (PLLOUT = CLKIN frequency * boot PLL Multiplier) must stay within thePLLOUT frequency range in Table 6-15 ,PLLC1 Clock Frequency Ranges.•Device Frequency: (SYSCLK1) calculated from Table 3-6 and Table 3-7 must not exceed theSYSCLK1 maximum frequency in Table 6-15 ,PLLC1 Clock Frequency Ranges.For example, for a 600-MHz device with a CLKIN = 27 MHz, in order to stay within the PLLOUTfrequency range and SYSCLK1 maximum frequency from Table 6-15 ,PLLC1 Clock FrequencyRanges, the user must select a boot mode with a PLL1 multiplier between x15 and x22.
As shown in Table 3-5 ,Table 3-6 , and Table 3-7 , there are different types of EMIFA Boot Modes. Thissubsection summarizes these types of EMIFA boot modes.

If AEM[2:0] = 001b, AEAW[2:0] must be configured to 100b.
This subsection discusses how the bootloader configures the clock dividers for the serial boot modes—I2Cboot, UART boot, and SPI boot.3.4.1.4.1 I2C Boot
If FASTBOOT = 0, then I2C Boot (BOOTMODE = 0101) is performed in Standard-Mode (up-to 100 kbps).If FASTBOOT = 1, then I2C Boot is performed in Fast-Mode (up-to 400 kbps). The actual I2C datatransfer rate is dependent on the MXI/CLKIN frequency.
This is how the bootloader programs the I2C:•I2C Boot in Fast-Mode (BOOTMODE[3:0] = 0101b, FASTBOOT = 1)– I2C register settings: ICPSC.IPSC = 2
10
, ICCLKL.ICCL = 8

, ICCKH.ICCH = 8

10
, ICCLKL.ICCL = 45
10
, ICCKH.ICCH = 45
10– Resulting in the following I2C prescaled module clock frequency (internal I2C clock):•(CLKIN frequency in MHz) / 3– Resulting in the following I2C serial clock (SCL):•SCL frequency (in kHz) = (CLKIN frequency in MHz) / 300 * 1000•SCL low pulse duration (in µs) = 150 / (CLKIN frequency in MHz)•SCL high pulse duration (in µs) = 150 / (CLKIN frequency in MHz)
Note: The I2C peripheral requires that the prescaled module clock frequency must be between 7 MHzand 12 MHz. Therefore, the I2C boot is only available for MXI/CLKIN frequency between 21 MHz and30 MHz.

3.4.1.4.2 UART Boot
For UART Boot (BOOTMODE[3:0] = 1000b or 1110b), the bootloader programs the UART0 peripheral asfollows:
•UART0 divisor is set to 15
10•Resulting in this UART0 baud rate in kilobit per second (kbps):– (CLKIN frequency in MHz) * 1000 / (15 * 16)
The user is responsible for ensuring the resulting baud rate is appropriate for the system. The UART0divisor (/15) is optimized for CLKIN frequency between 27 to 29 MHz to stay within 5% of the 115200-bpsbaud rate.
For more details on the UART peripheral configurations and clock generation, see the TMS320DM643xDMP Universal Asynchronous Receiver/Transmitter (UART) User's Guide (literature number SPRU997 ).3.4.1.4.3 SPI Boot
Both 16-bit address SPI Boot (BOOTMODE = 0110) and 24-bit address SPI boot are performed throughthe McBSP0 peripheral. The bootloader programs the McBSP0 peripheral as follows:•McBSP0 register settings: SRGR.CLKGDV = 2
10•Resulting in this SPI serial clock frequency:– (SYSCLK3 frequency in MHz) / 3
SYSCLK3 frequency = SYSCLK1 frequency / 6. SYSCLK1 frequency during boot can be found inTable 3-5 ,Table 3-6 ,Table 3-7 , and/or Table 3-8 based on the boot mode selection.
For example, if BOOTMODE[3:0] = 0110b, FASTBOOT = 1, the MXI/CLKIN frequency = 27 MHz,AEM[2:0] = 000b, PLLMS[2:0] = 100b, the combination of Table 3-7 and Table 3-8 indicates that thedevice frequency (SYSCLK1) is CLKIN x 22 / 2 = 297 MHz. This means SYSCLK3 frequency is297 / 6 = 49.5 MHz, resulting in SPI serial clock frequency of 49.5 / 3 = 16.5 MHz.
The DM6433 supports two types of host boots—PCI Boot or HPI Boot.
The PCI Boot (BOOTMODE[3:0] = 0001b or 0010b, PCIEN = 1) is only available in fastboot(FASTBOOT = 1), as shown in Table 3-6 and Table 3-7 .
The HPI Boot is available in fastboot and non-fastboot, as shown in Table 3-5 ,Table 3-6 , and Table 3-7 .
Note: The HPI HSTROBE inactive pulse duration timing requirement [t
w(HSTBH)
] is dependent on the HPIinternal clock source (SYSCLK3) frequency (see Section 6.13.3 ,HPI Electrical Data/Timing). The externalhost must be aware of the SYSCLK3 frequency during boot to ensure the HSTROBE pulse durationtiming requirement is met.

SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
If the bootloader code detects an error during boot, it records the error status in the Boot Complete(BOOTCMPLT) register.
In addition, the BOOTCMPLT register is used for communication between the external host and thebootloader code during a Host Boot (HPI Boot or PCI Boot). Once the external host has completed boot, itmust perform the following communication with the bootloader code:•Write the desired 32-bit CPU starting address in the DSPBOOTADDR register (see Section 3.4.2.3 ,DSPBOOTADDR Register).•Write a ‘1’ to the Boot Complete (BC) bit field in the BOOTCMPLT register to indicate that the host hascompleted booting this device.
Once the bootloader code detects BC = 1, it directs the CPU to begin executing from theDSPBOOTADDR register.
The BOOTCMPLT register is reset by any device-level global reset. For the list of device-level globalresets, see Section 6.5 ,Reset.

The DSP Boot Address (DSPBOOTADDR) register contains the starting address for the C64x+ CPU.Whenever the C64x+ is released from reset, it begins executing from the location pointed to byDSPBOOTADDR register. For Host boots (HPI Boot or PCI Boot), the DSPBOOTADDR register is alsoused for communication between the Host and the bootloader code during boot.
The DSPBOOTADDR register is reset by any device-level global reset. For the list of device-level globalresets, see Section 6.5 ,Reset.

DSP Boot Address
After boot, the C64x+ CPU begins execution from this 32-bit address location. The lower 10 bits(bits 9:0) should always be programmed to "0" as they are ignored by the C64x+. The defaultvalue of the DSPBOOTADDR depends on the boot mode selected.
31:0 DSPBOOTADDR The DSPBOOTADDR defaults to 0x0010 0000 when the Internal Bootloader ROM is used.or
The DSPBOOTADDR defaults to 0x4200 0000 when EMIFA CS2 Space is used.
For the boot mode selections, see Table 3-5 ,Non-Fastboot Modes;Table 3-6 ,Fixed-MultiplierFastboot Modes; and Table 3-7 ,User-Select Multiplier Fastboot Modes.
For Non-Host Boot Modes, software can leave the DSPBOOTADDR register at default.
For Host Boots (HPI Boot or PCI Boot), the DSPBOOTADDR register is also used for communicationbetween the Host and the bootloader code during boot. For Host Boots, the DSPBOOTADDR registerdefaults to Internal Bootloader ROM, and the C64x+ CPU is immediately released from reset so that it canbegin executing the bootloader code in this internal ROM. The bootloader code waits for the Host to bootthe device. Once the Host is done booting the device, it must write a new starting address into theDSPBOOTADDR register, and follow with writing BOOTCMPLT.BC = 1 to indicate the boot is complete.As soon as the bootloader code detects BOOTCMPLT.BC = 1, it instructs the CPU to jump to this newDSPBOOTADDR address. At this point, the CPU continues the rest of the code execution starting fromthe new DSPBOOTADDR location and the boot is completed.

For proper device operation, external pullup/pulldown resistors may be required on these device boot andconfiguration pins. For discussion situations where external pullup/pulldown resistors are required, seeSection 3.9.1 ,Pullup/Pulldown Resistors.
Note: Except for PCIEN, all other DM6433 configuration inputs (BOOTMODE[3:0], FASTBOOT,AEAW[2:0]/PLLMS[2:0] and AEM[2:0]) are multiplexed with other functional pins. These pins function asdevice boot and configuration pins only during device reset. The user must take care of any potential datacontention in the system. To help avoid system data contention, the DM6433 puts these configuration pinsinto a high-impedance state (Hi-Z) when device reset ( RESET or POR) is asserted, and continues to holdthem in a high-impedance state until the internal global reset is removed; at which point, the defaultperipheral (either GPIO or EMIFA based on default of AEM[2:0]) will now control these pins.
All of the device boot and configuration pin settings are captured in the corresponding bit fields in theBOOTCFG register (see Section 3.4.2.1 ).
The following subsections provide more details on the device configurations determined at device reset:AEM, AEAW/PLLMS, and PCIEN.
To support different usage scenarios, the DM6433 provides intricate pin multiplexing between the EMIFAand other peripherals. The PINMUX0.AEM register bit field in the System Module determines the EMIFAPinout Mode. The AEM[2:0] pins only select the default EMIFA Pinout Mode. It is latched at device resetde-assertion (high) into the BOOTCFG.DAEM bit field. The AEM[2:0] value also sets the default of thePINMUX0.AEM bit field. While the BOOTCFG.DAEM bit field shows the actual latched value and cannotbe modified, the PINMUX0.AEM value can be changed by software to modify the EMIFA Pinout Mode.
Note: The AEM[2:0] value does not affect the operation of the EMIFA module itself. It only affects whichEMIFA pins are brought out to the device pins. For more details on the AEM settings, see Section 3.7 ,Multiplexed Pin Configurations.
In addition, for Fastboot modes (FASTBOOT = 1), the bootloader code determines the PLL1 multiplierbased on the default settings of AEM[2:0] and PLLMS[2:0]. For more details, see Section 3.4.1.1 ,Fastboot, and Section 3.5.1.2 ,EMIFA Address Width Select (AEAW) and FASTBOOT PLL MultiplierSelect (PLLMS).
The AEAW[2:0]/PLLMS[2:0] pins serve two functional purposes (AEAW or PLLMS), depending on theFASTBOOT and AEM settings. The AEAW[2:0]/PLLMS[2:0] pins are latched at device reset de-assertion(high) and captured in the BOOTCFG.PLLMS bit field. This value also sets the default of thePINMUX0.AEAW field.
While the BOOTCFG.PLLMS field shows the actual latched value and cannot be modified, thePINMUX0.AEAW value can be changed by software to modify the EMIFA pinout.
AEAW as EMIFA Address Width Select (AEAW)
If AEM[2:0] = 001b [8-bit EMIFA (Async) Pinout Mode 1], the AEAW[2:0]/PLLMS[2:0] pins serve as AEAWto set the default of the EMIFA Address Width Selection.
On DM6433, only AEAW = 100b is supported. If AEM[2:0] = 001b [8-bit EMIFA (Async) Pinout Mode 1],AEAW must be set to 100b to select full addres width for EMIFA. For other EMIFA Pinout Modes (AEMnot 001b), AEAW is not applicable in determining the EMIFA address width.
Note: AEAW[2:0] value does not affect the operation of the EMIFA module itself.

For more information on boot modes and the FASTBOOT PLL multiplier selection, see Section 3.4.1 ,BootModes.
The PCIEN configuration pin determines if the PCI peripheral is used on this device. If PCIEN = 1indicating 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, and the pins’ corresponding internalpullup/pulldown resistors are enabled.
The PCIEN setting is captured and stored in the BOOTCFG.DPCIEN bit field, and also in thePINMUX1.PCIEN bit field. These values cannot be changed by software. Furthermore, for proper deviceoperation, the user must hold the desired setting at the PCIEN pin throughout device operation.

DM6433 makes extensive use of pin multiplexing to accommodate a large number of peripheral functionsin the smallest possible package, providing ultimate flexibility for end applications.
The Pin Multiplex Registers PINMUX0 and PINMUX1 in the System Module are responsible for controllingall pin multiplexing functions on the DM6433. The default setting of some of the PINMUX0 and PINMUX1bit fields are configured by configuration pins latched at reset (see Section 3.5.1 ,Device and PeripheralConfigurations at Device Reset). After reset, software may program the PINMUX0 and PINMUX1 registersto switch pin functionalities.
The following peripherals have multiplexed pins: VPSS (VPBE), EMIFA, PCI, HPI, VLYNQ, EMAC,McASP0, McBSP0, PWM0, PWM1, PWM2, Timer0, Timer1, UART0, and GPIO.
The device is divided into the following Pin Multiplexed Blocks (Pin Mux Blocks):•EMIFA/VPSS Block: VPSS (VPBE), EMIFA, part of PCI, GPIO. This block is further subdivided intothese sub-blocks:
–Sub-Block 0: part of EMIFA (data, address, control), part of PCI, and GPIO–Sub-Block 1: VPBE (VENC), part of EMIFA (data, address, control), and GPIO–Sub-Block 2: part of EMIFA (control signals EM_WAIT/(RDY/ BSY), EM_OE, and EM_WE)–Sub-Block 3: part of EMIFA (address EM_A[12:5]), part of PCI, and GPIO•Host Block: HPI, VLYNQ, EMAC, part of PCI, and GPIO•PCI Data Block: part of PCI•GPIO Block: part of PCI and GPIO•Serial Port Block: McBSP0, McASP0, and GPIO. This block is further sub-divided into sub-blocks.–Serial Port Sub-Block 0: McBSP0, part of McASP0, and GPIO–Serial Port Sub-Block 1: part of McASP0, and GPIO•UART0 Flow Control Block: UART0 flow control, PWM0, and GPIO•UART0 Data Block: UART0 data and GPIO•Timer0 Block: Timer0 and McBSP0 CLKS pins•Timer1 Block: Timer1•PWM1 Block: PWM1 and GPIO•CLKOUT Block: CLKOUT0, PWM2, and GPIO
As shown in the list above, the PCI, McBSP0, and UART0 peripherals span multiple Pin Mux Blocks. Touse these peripherals, they must be selected in all relevant Pin Mux Blocks. For more details, seeSection 3.7.3 ,Pin Multiplexing Details, and Section 3.7.3.2 ,Peripherals Spanning Multiple Pin MuxBlocks.
Note: There is no actual pin multiplexing in EMIFA/VPSS Sub-Block 2 and the PCI Data Block. Howeverthese are still considered "pin mux blocks" because they contain part of the pins necessary for EMIFA andPCI, respectively.
A high level view of the Pin Mux Blocks is shown in Figure 3-11 . In each Pin Mux Block, thePINMUX0/PINMUX1 default settings are underlined.
Note: Some default pin functions are determined by configuration pins (PCIEN, AEAW[2:0], AEM[2:0]);therefore, more than one configuration setting can serve as default based on the configuration pin settingslatched at device reset.

3.7.2.1 PINMUX0 Register Description
TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The PINMUX0 and PINMUX1 registers in the System Module allow software to select the pin functions inthe Pin Mux Blocks. The pin control of some of the Pin Mux Blocks requires a combination ofPINMUX0/PINMUX1 bit fields. For more details on the combination of the PINMUX bit fields that controleach muxed pin, see Section 3.7.3.1 ,Multiplexed Pins on DM6433.
This section only provides an overview of the PINMUX0 and PINMUX1 registers. For more detaileddiscussion on how to program each Pin Mux Block, see Section 3.7.3 ,Pin Multiplexing Details.
The Pin Multiplexing 0 Register (PINMUX0) controls the pin function in the EMIFA/VPSS Block. ThePINMUX0 register format is shown in Figure 3-12 and the bit field descriptions are given in Table 3-19 .Some muxed pins are controlled by more than one PINMUX bit field. For the combination of the PINMUXbit fields that control each muxed pin, see Section 3.7.3.1 ,Multiplexed Pins on DM6433. For moreinformation on EMIFA/VPSS Block pin muxing, see Section 3.7.3.13 ,EMIFA/VPSS Block Muxing. For thepin-by-pin muxing control of the EMIFA/VPSS Block, see Section 3.7.3.13.7 ,EMIFA/VPSS BlockPin-By-Pin Multiplexing Summary.
Note: In addition to PINMUX0 bit fields, the EMIFA/VPSS Block also requires the PCIEN bit in the PinMultiplexing 1 Register (PINMUX1, Section 3.7.2.2 ) to determine the PCI settings.31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16

As discussed in Section 3.7.3.2 ,Peripherals Spanning Multiple Pin Mux Blocks, PCI pins span across thefollowing Pin Mux Blocks: Host Block, EMIFA/VPSS Block Sub-Block 0 and Sub-Block 3, PCI Data Block,and GPIO Block. For proper PCI operation, PCI must be selected in all of these Pin Mux Blocks.
The EMBK0, EMBK1, EMBK2, EMBK3 fields in the VDD3P3V_PWDN register determine the power stateof the EMIFA/VPSS Block pins. The EMIFA/VPSS Block pins default to powered up. For more details onthe EMBK0, EMBK1, EMBK2, EMBK3 fields in the VDD3P3V_PWDN register, see Section 3.2 ,PowerConsiderations.
To understand pin multiplexing in the EMIFA/VPSS Block, the user should start with Section 3.7.3.13.1 ,EMIFA/VPSS Block Pin Selection Procedure, which outlines the procedures to select pin functions of thisblock. Section 3.7.3.13.7 ,EMIFA/VPSS Block Pin-By-Pin Multiplexing Summary, provides a pin-by-pinmultiplexing summary for the EMIFA/VPSS Block. For more information on the PINMUX0 and PINMUX1registers, see Section 3.7.2 ,Pin Muxing Selection After Device Reset.3.7.3.13.1 EMIFA/VPSS Block Pin Selection Procedure
Follow the steps below to perform pin selection for the EMIFA/VPSS Block and its sub-blocks.
1. Major Configuration Options: start with Table 3-42 ,EMIFA/VPSS Block Major Configuration Choices.Based on the peripheral needs, the user should select from the major configuration options in thisblock: Major Config Options A, B, C, D, E, F, G.2. Sub-Block 0, Sub-Block 2, and Sub-Block 3 Selection: After selecting the major configuration optionfrom Table 3-42 ,EMIFA/VPSS Block Major Configuration Choices, the pin selection for Sub-Block 0,Sub-Block 2, and Sub-Block 3 is complete.3. Sub-Block 1 Selection: Use Table 3-44 through Table 3-48 ,EMIFA/VPSS Sub-Block 1 ConfigurationChoices, to refine Sub-Block 1 pin selection.a. Go to the table with the Major Configuration Option chosen in Step 1.b. Each Major Configuration Option is further divided down into multiple Minor Configuration Options.Select a Minor Configuration Option that best suits the application need.c. Within the chosen Minor Configuration Option, further refine the detailed pin configurations byselecting the settings of PINMUX0 fields VENCSEL, RGBSEL, CS3SEL, CS4SEL, and CS5SEL.d. The Selection Fields columns shows the settings needed to program the PINMUX0 register.
After following the procedure in this section to determine pin functions for the EMIFA/VPSS Block, theuser should refer to Section 3.7.3.13.7 ,EMIFA/VPSS Block Pin-By-Pin Multiplexing Summary, forpin-multiplexing information on a pin-by-pin basis.

The following is an example on how to read Table 3-42 . For example, the "PINMUX Selection Fields"columns indicate that Major Configuration Choice B is selected through setting PINMUX1.PCIEN = 0,PINMUX0.AEM = 1, and VENCSEL = 0 or 1 (based on the system's VPBE requirement). The "ResultingPeripherals/Pins" columns indicate that Major Configuration Option B can support the followingcombination of pin functions:•No PCI pins•Pins for 8-bit EMIFA (Async or NAND) function. The number of address pins supported provide16MByte address reach per EMIFA Chip Select (CS) space.•Pins for up to 8-bit VPBE. If 8-bit VPBE (VENCSEL = 1) is selected, the user may have 0 to 4 GPIOpins. Exact detail on number of GPIO pins and VPBE control pins is further determined by otherPINMUX0 settings discussed in the EMIFA/VPSS Sub-Block 1 Configuration Choices.•11 GPIO pins (GP[54:52, 43:36]) from EMIFA/VPSS Sub-Block 0.
After using Table 3-42 to select the Major Configuration Option for the EMIFA/VPSS Block, proceed toselect the detailed pin choices in the EMIFA/VPSS Sub-Blocks.3.7.3.13.3 EMIFA/VPSS Sub-Block 0 Configuration Choices
The pins in the EMIFA/VPSS Sub-Block 0 are muxed between part of EMIFA, part of PCI, and GPIO. Thepin functions in the EMIFA/VPSS Sub-Block 0 are determined by the following PINMUX register fields:•PINMUX1.PCIEN

As shown in Table 3-44 through Table 3-48 , the configuration choices of the EMIFA/VPSS Sub-Block 1are determined by the following PINMUX register fields:•PINMUX0 register fields AEM, VENCSEL, RGBSEL, CS3SEL, CS4SEL, CS5SEL, and VPBECKEN.
The following is an example on how to read Table 3-44 through Table 3-48 using Sub-Block 1 MinorConfiguration G2 as an example:•The PINMUX Selection Fields columns indicate that Sub-Block 1 Minor Configuration Option G2 isselected through setting PINMUX0 fields to AEM = 5, VENCSEL = 1, RGBSEL = 0 or 1 (based onwhether the VPBE LCD_FIELD pin is needed), CS3SEL = 0/1/2 (based on the desired pin choice),CS4SEL = 0/1/2 (based on the desired pin choice), CS5SEL = 0/1/2 (based on the desired pin choice),and VPBECKEN = 0/1 (based on whether VPBE VPBECLK is needed).•The Resulting Peripherals/Pins columns show the functional pins resulting from the PINMUX setting.For example, PINMUX0.VENCSEL = 1 gives you the VCLK and YOUT[7:0] pins for the VPBE, inaddition to EM_D[7:0] pins for the EMIFA. PINMUX0.RGBSEL = 1 gives you the LCD_FIELD pin forthe VPBE, along with EM_A[2:1] and EM_CS2 for the EMIFA, and 4 GP pins.

3.7.3.13.7 EMIFA/VPSS Block Pin-By-Pin Multiplexing Summary
This section summarizes the EMIFA/VPSS Block muxing on a pin-by-pin basis. It provides an alternativeview to pin muxing in the EMIFA/VPSS Block. This section should only be used after following theprocedures listed in Section 3.7.3.13.1 to determine the actual EMIFA/VPSS Configuration Option for theapplication need.
Table 3-50 shows the pin multiplexing control for each pin in the EMIFA/VPSS Sub-Block 0. These are thefields in the PINMUX0 and PINMUX1 registers that control the multiplexing in this sub-block:•PINMUX0: AEM and AEAW•PINMUX1: PCIEN
Table 3-51 shows the pin multiplexing control for each pin in the EMIFA/VPSS Sub-Block 1. These are thefields in the PINMUX0 register that control the multiplexing in this sub-block:•PINMUX0: AEM, VENCSEL, RGBSEL, CS5SEL, CS4SEL, CS3SEL, VPBECKEN
EMIFA/VPSS Sub-Block 2 is dedicated to EMIFA pins EM_WAIT/(RDY/ BSY), EM_OE, and EM_WE.There is no pin multiplexing in this block. These pins always function as EMIFA control pins.
Table 3-52 shows the pin multiplexing control for each pin in the EMIFA/VPSS Sub-Block 3. These are thefields in the PINMUX0 and PINMUX1 registers that control the multiplexing in this sub-block:•PINMUX0: AEM•PINMUX1: PCIEN

3.8 Device Initialization Sequence After Reset
TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
Software should follow this initialization sequence after coming out of device reset.1. Complete the boot sequence as needed. For more details on the boot sequence, see the Using theTMS320DM643x Bootloader Application Report (literature number SPRAAG0 ).2. If the device is not already at the desired operating frequency, program the PLL Controllers (PLLC1and PLLC2) to configure the device frequency. For details on how to program the PLLC, see theTMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978 ).3. Program PINMUX0 and PINMUX1 registers to select device pin functions. For more details onprogramming the PINMUX0 and PINMUX1 registers to select device pin functions, see Section 3.7 ,Multiplexed Pin Configurations.Note: If EMAC operation is desired, the EMAC must be placed in reset before programmingPINMUX1.HOSTBK to select EMAC pins.4. Program the VDD3P3V_PWDN register to power up the necessary I/O pins. For more details onprogramming the VDD3P3V_PWDN register, see Section 3.2 ,Power Considerations.5. As needed by the application, program the following System Module registers when there are no activetransactions on the respective peripherals:a. HPICTL (Section 3.6.2.1 ,HPI Control Register): applicable for HPI only if a different host burstwrite timeout value from default is desired.b. TIMERCTL (Section 3.6.2.2 ,Timer Control Register): applicable for Timer0 and Watchdog Timer2only.
c. EDMATCCFG (Section 3.6.2.3 ,EDMA TC Configuration Register): applicable for EDMA only. Therecommendation is to leave the EDMATCCFG register at its default.d. VPSS_CLKCTL (Section 3.3.1.2.1 ,VPSS Clocks): applicable for VPSS only.6. Program the Power and Sleep Controller (PSC) to enable the desired peripherals. For details on howto program the PSC, see the TMS320DM643x DMP DSP Subsystem Reference Guide (literaturenumber SPRU978 ).7. Program the Switched Central Resource (SCR) bus priorities for the master peripherals(Section 3.6.1 ). This must be configured when there are no active transactions on the respectiveperipherals:
a. Program the MSTPRI0 and MSTPRI1 registers in the System Module. These registers can beprogrammed before or after the respective peripheral is enabled by the PSC in step 6.b. Program the EDMACC QUEPRI register, the C64x+ MDMAARBE.PRI field, and the VPSS PCRregister. These registers can only be programmed after the respective peripheral is enabled by thePSC in step 6.8. Configure the C64x+ Megamodule and the peripherals.a. For details on C64x+ Megamodule configuration, see the TMS320C64x+ DSP MegamoduleReference Guide (literature number SPRU871 ).
Special considerations: Bootloader disables C64x+ cache—For all boot modes that default toDSPBOOTADDR = 0x0010 0000 (i.e., all boot modes except the EMIFA ROM Direct Boot,BOOTMODE[3:0] = 0100, FASTBOOT = 0), the bootloader code disables all C64x+ cache (L2,L1P, and L1D) so that upon exit from the bootloader code, all C64x+ memories are configured asall RAM (L2CFG.L2MODE = 0h, L1PCFG.L1PMODE = 0h, and L1DCFG.L1DMODE = 0h). If cacheuse is required, the application code must explicitly enable the cache. For more information on bootmodes, see Section 3.4.1 ,Boot Modes. For more information on the bootloader, see the Using theTMS320DM643x Bootloader Application Report (literature number SPRAAG0 ).

b. Peripherals configuration: see the respective peripheral user’s guide.
Special considerations: DDR2 memory controller—the Peripheral Bus Burst Priority Register(PBBPR) should be programmed to ensure good DDR2 throughput and to prevent commandstarvation (prevention of certain commands from being processed by the DDR2 memory controller).For more details, see the TMS320DM643x DMP DDR2 Memory Controller User’s Guide (literaturenumber SPRU986 ). A hex value of 0x20 is recommended for the PBBPR PR_OLD_COUNT field toprovide a good DSP performance and still allow good utilization by other modules.

3.9 Debugging Considerations
3.9.1 Pullup/Pulldown Resistors
TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
Proper board design should ensure that input pins to the DM643x DMP device always be at a valid logiclevel and not floating. This may be achieved via pullup/pulldown resistors. The DM643x DMP featuresinternal pullup (IPU) and internal pulldown (IPD) resistors on most pins to eliminate the need, unlessotherwise 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 externalpullup/pulldown resistor is strongly recommended, even if the IPU/IPD matches the desiredvalue/state.
•Other Input Pins: If the IPU/IPD does not match the desired value/state, use an externalpullup/pulldown resistor to pull the signal to the opposite rail.•EMIFA Chip Select Outputs: On DM6433, the EMIFA chip select pins ( EM_CS2, EM_CS3, EM_CS4,and EM_CS5) feature an internal pulldown (IPD) resistor. If these pins are connected and used as anEMIFA chip select signal, for proper device operation, an external pullup resistor must be used toensure the EM_CSx function defaults to an inactive (high) state.
For the boot and configuration pins (listed in Table 2-5 ,Boot Terminal Functions), if they are both routedout and 3-stated (not driven), it is strongly recommended that an external pullup/pulldown resistor beimplemented. Although, internal pullup/pulldown resistors exist on these pins and they may match thedesired configuration value, providing external connectivity can help ensure that valid logic levels arelatched on these device boot and configuration pins. In addition, applying external pullup/pulldownresistors on the boot and configuration pins adds convenience to the user in debugging and flexibility inswitching 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 sureto include the leakage currents of all the devices connected to the net, as well as any internal pullup orpulldown resistors.•Decide a target value for the net. For a pulldown resistor, this should be below the lowest V
IL
level ofall inputs connected to the net. For a pullup resistor, this should be above the highest V
IH
level of allinputs on the net. A reasonable choice would be to target the V
OL
or V
OH
levels for the logic family ofthe limiting device; which, by definition, have margin to the V
IL
and V
IH
levels.•Select a pullup/pulldown resistor with the largest possible value; but, which can still ensure that the netwill reach the target pulled value when maximum current from all devices on the net is flowing throughthe resistor. The current to be considered includes leakage current plus, any other internal andexternal pullup/pulldown resistors on the net.•For bidirectional nets, there is an additional consideration which sets a lower limit on the resistancevalue of the external resistor. Verify that the resistance is small enough that the weakest output buffercan 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 DV
DD
rail.
For most systems, a 1-k Ωresistor 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-k Ωresistor can be used to compliment the IPU/IPD on the boot and configurationpins while meeting the above criteria. Users should confirm this resistor value is correct for their specificapplication.

SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
On the DM6433 device, the C64x+ Megamodule, the EDMA3 transfer controllers, and the systemperipherals are interconnected through a switch fabric architecture (see Figure 4-1 ). The switch fabric iscomposed of multiple switched central resources (SCRs) and multiple bridges. The SCRs establishlow-latency connectivity between master peripherals and slave peripherals. Additionally, the SCRs providepriority-based arbitration and facilitate concurrent data movement between master and slave peripherals.Through an SCR, the DSP subsystem can send data to the DDR2 Memory Controller without affecting adata transfer between the EMAC and L2 memory. Bridges are mainly used to perform bus-widthconversion as well as bus operating frequency conversion. For example, in Figure 4-1 , Bridge 6 performsa frequency conversion between a bus operating at DSP/3 clock rate and a bus operating at DSP/6 clockrate. Furthermore, Bridge 5 performs a bus-width conversion between a 64-bit bus and a 32-bit bus.
The C64x+ Megamodule, the EDMA3 transfer controllers (EDMA3TC[2:0]), and the various systemperipherals can be classified into two categories: master peripherals and slave peripherals. Masterperipherals are typically capable of initiating read and write transfers in the system and do not rely on theEDMA3 or on the CPU to perform transfers to and from them. The system master peripherals include theC64x+ Megamodule, the EDMA3 transfer controllers, VLYNQ, EMAC, HPI, PCI, and VPSS. Not all masterperipherals may connect to all slave peripherals. The supported connections are designated by "Y" inTable 4-1 .

Figure 4-1 displays the DM6433 system interconnect block diagram. The following is a list that helps inthe interpretation of this diagram:•The direction of the arrows indicates either a bus master or bus slave.•The arrow originates at a bus master and terminates at a bus slave.•The direction of the arrows does not indicate the direction of data flow. Data flow is typicallybi-directional for each of the documented bus paths.•The pattern of each arrow's line indicates the clock rate at which it is operating— i.e., either DSP/3,DSP/6, or MXI/CLKIN clock rate.•A peripheral may have multiple instances shown in Figure 4-1 for the following reason:– The peripheral/module has master port(s) for data transfers, as well as slave port(s) for registeraccess, data access, and/or memory access. Examples of these peripherals are C64X+Megamodule, EDMA3, VPSS, VLYNQ, HPI, EMAC, and PCI.

TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze thetiming characteristics correctly. To properly use IBIS models to attain accurate timing analysis for a givensystem, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839 ). Ifneeded, 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 timingcharacteristics. TI provides a PCB routing rules solution that describes the routing rules to ensure theDDR2 memory controller interface timings are met. See the Implementing DDR2 PCB Layout on theTMS320DM643x DMP DMSoC Application Report (literature number SPRAAL6 ).
All clocks and control signals must transition between V
IH
and V
IL
(or between V
IL
and V
IH
) in a monotonicmanner.
For more information regarding TI's power management products and suggested devices to power TIDSPs, visit www.ti.com/dsppower .
The DM6433 includes one core supply (CV
DD
), and two I/O supplies—DV
DD33
and DV
DDR2
. To ensureproper device operation, a specific power-up sequence must be followed. Some TI power-supply devicesinclude features that facilitate power sequencing—for example, Auto-Track and Slow-Start/Enablefeatures. For more information on TI power supplies and their features, visit www.ti.com/dsppower .
Here is a summary of the power sequencing requirements:•The power ramp order must be DV
DD33
before DV
DDR2
, and DV
DDR2
before CV
DD
—meaning duringpower up, the voltage at the DV
DDR2
rail should never exceed the voltage at the DV
DD33
rail. Similarly,the voltage at the CV
DD
rail should never exceed the voltage at the DV
DDR2
rail.•From the time that power ramp begins, all power supplies (DV
DD33
, DV
DDR2
, CV
DD
)must be stablewithin 200 ms. The term "stable" means reaching the recommended operating condition (seeSection 5.2 ,Recommended Operating Conditions table).
Core and I/O supply voltage regulators should be located close to the DSP to minimize inductance andresistance in the power delivery path. Additionally, when designing for high-performance applicationsutilizing the DM6433 device, the PC board should include separate power planes for core, I/O, andground; all bypassed with high-quality low-ESL/ESR capacitors.
In order to properly decouple the supply planes from system noise, place as many capacitors (caps) aspossible close to the DSP. These caps need to be close to the DSP, no more than 1.25 cm maximumdistance to be effective. Physically smaller caps are better, such as 0402, but need to be evaluated from ayield/manufacturing point-of-view. Parasitic inductance limits the effectiveness of the decouplingcapacitors, therefore physically smaller capacitors should be used while maintaining the largest availablecapacitance value.
Larger caps for each supply can be placed further away for bulk decoupling. Large bulk caps (on the orderof 100 µF) should be furthest away, but still as close as possible. Large caps for each supply should beplaced outside of the BGA footprint.
As with the selection of any component, verification of capacitor availability over the product's productionlifetime should be considered.
For more details on capacitor usage and placement, see the Implementing DDR2 PCB Layout on theTMS320DM643x DMP DMSoC Application Report (literature number SPRAAL6 ).

6.3.4 DM6433 Power and Clock Domains
TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The DM6433 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 CV
DD
pins ofthe DM6433. All DM6433 modules lie within the "Always On" power domain. Table 6-1 provides a listing ofthe DM6433 clock domains.
One primary reference clock is required for the DM6433 device. It can be either a crystal input or driven byexternal oscillators. A 27-MHz crystal is recommended for the PLLs, which generate the internal clocks forthe digital media processor (DMP), peripherals, and EDMA3.
The DM6433 architecture is divided into the power and clock domains shown in Table 6-1 .Table 6-2 andTable 6-3 further discuss the clock domains and their ratios. Figure 6-4 shows the Clock Domain blockdiagram.

TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The Power and Sleep Controller (PSC) controls power by turning off unused power domains or by gatingoff clocks to individual peripherals/modules. The DM6433 device only utilizes the clock gating feature ofthe PSC for power savings. 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 eachperipheral/module. An LPSC is associated with each peripheral/module and provides clock and resetcontrol. The LPSCs for DM6433 are shown in Table 6-4 . The PSC Register memory map is given inTable 6-5 . For more details on the PSC, see the TMS320DM643x DMP DSP Subsystem Reference Guide(literature number SPRU978 ).

6.4 Enhanced Direct Memory Access (EDMA3) Controller
6.4.1 EDMA3 Channel Synchronization Events
TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The EDMA controller handles all data transfers between memories and the device slave peripherals onthe DM6433 device. 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– DSP L1D memory– DSP L2 memory•Transfer to/from external storage– DDR2 SDRAM– NAND flash– Asynchronous EMIF (EMIFA)•Transfer to/from peripherals/hosts– VLYNQ
– HPI– McBSP0
– McASP0
– PWM
– UART0
– PCI
The EDMA supports two addressing modes: constant addressing and increment addressing. On theDM6433, constant addressing mode is not supported by any peripheral or internal memory. For moreinformation on these two addressing modes, see the TMS320DM643x DMP Enhanced Direct MemoryAccess (EDMA3) Controller User's Guide (literature number SPRU987 ).
The EDMA supports up to 64 EDMA channels which service peripheral devices and external memory.Table 6-6 lists the source of EDMA synchronization events associated with each of the programmableEDMA channels. For the DM6433 device, the association of an event to a channel is fixed; each of theEDMA channels has one specific event associated with it. These specific events are captured in theEDMA 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 TMS320DM643x DMP Enhanced DirectMemory Access (EDMA3) Controller User's Guide (literature number SPRU987 ).

6.5 Reset
6.5.1 Power-on Reset ( POR Pin)

SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The reset controller detects the different type of resets supported on the DM6433 device and manages thedistribution of those resets throughout the device.
The DM6433 device has several types of device-level global resets - power-on reset, warm reset, andmax reset. Table 6-10 explains further the types of reset, the reset initiator, and the effects of each reseton the chip. See Section 6.5.9 ,Reset Electrical Data/Timing, for more information on the effects of eachreset on the PLL controllers and their clocks.
Table 6-10. Device-Level Global Reset Types
TYPE INITIATOR EFFECT(s)
POR pin Global chip reset (Cold reset). Activates the POR signal on chip,which resets the entire chip including the emulation logic.Power-on Reset
The power-on reset ( POR) pin must be driven low during power(POR)
ramp of the device.Device boot and configuration pin are latched.Resets everything except for the emulation logic. Emulator staysWarm Reset RESET pin alive during Warm Reset.Device boot and configuration pin are latched.Same as a Warm Reset, except the DM6433 device boot andMax Reset Emulator, WD Timer (Timer 2)
configuration pins are not re-latched.
In addition to device-level global resets, the PSC provides the capability to cause local resets toperipherals and/or the CPU.
Power-on Reset (POR) is initiated by the POR pin and is used to reset the entire chip, including theemulation logic. Power-on Reset is also referred to as a cold reset since the device usually goes through apower-up cycle. During power-up, the POR pin must be asserted (driven low) until the power supplieshave reached their normal operating conditions. If an external 27-MHz oscillator is used on the MXI/CLKINpin, 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 MXI cycles.
Within the low period of the POR pin, the following happens:– The reset signals flow to the entire chip (including the emulation logic), resetting the modules onchip.
– The PLL Controller clocks start at the frequency of the MXI clock. The clocks are propagatedthroughout the chip to reset the chip synchronously. By default, both PLL1 and PLL2 are in resetand unlocked. The PLL Controllers default to PLL Bypass Mode.– The RESETOUT pin stays asserted (low), indicating the device is in reset.4. The POR pin may now be deasserted (driven high).
When the POR pin is deasserted (high), the configuration pin values are latched and the PLLControllers changed their system clocks to their default divide-down values. Both PLL Controllers arestill 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 theend of these 10 cycles, the RESETOUT pin is deasserted (driven high).

– The I/O pins are controlled by the default peripherals (default peripherals are determined byPINMUX0 and PINMUX1 registers).– The clock and reset of each peripheral is determined by the default settings of the Power and SleepController (PSC).– The PLL Controllers are operating in PLL Bypass Mode.– The C64x+ begins executing from DSPBOOTADDR (determined by bootmode selection).
After the reset sequence, the boot sequence begins. For more details on the boot sequence, see theUsing the TMS320DM643x Bootloader Application Report (literature number SPRAAG0 ).
After the boot sequence, follow the software initialization sequence described in Section 3.8 ,DeviceInitialization Sequence After Reset.
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 thedevice.
In functional end-system, emulation/debugger logic is typically not needed; therefore, the recommendationfor functional end-system is to use the POR pin for full device reset. If RESET pin is not needed, it can bepulled 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 emulationsession. In this case, the user can use the POR pin to achieve full device reset and use the RESET pin toachieve a debug reset—which resets the entire device except emulation logic.
Internal to the chip, the two device reset pins RESET and POR are logically AND’d together only for thepurpose of latching device boot and configuration pins. The values on all device and boot configurationpins are latched into the BOOTCFG register when the logical AND of RESET and POR transitions fromlow-to-high.
A Warm Reset is activated by driving the RESET pin active low. This resets everything in the deviceexcept the emulation logic. An emulator session will stay alive during warm reset.
For more information on POR vs. RESET usage, see Section 6.5.1.1 ,Usage of POR versus RESET Pinsand Section 6.5.1.2 ,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 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 emulationlogic.
– The PLL Controllers are reset thereby, switching back to PLL Bypass Mode and resetting all theirregisters to default values. Both PLL1 and PLL2 are placed in reset and lose lock.– The RESETOUT pin becomes asserted (low), indicating the device is in reset.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 PLLControllers changed their system clocks to their default divide-down values. Both PLL Controllers arestill in PLL Bypass Mode. Other device initialization also begins.4. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At theend of these 10 cycles, the RESETOUT pin is deasserted (driven high).

A Maximum (Max) Reset is initiated by the emulator or the watchdog timer (Timer 2). The effects are thesame as a warm reset, except the device boot and configuration pins are not re-latched. The emulatorinitiates a maximum reset via the ICEPICK module. This ICEPICK initiated reset is non-maskable. Whenthe watchdog timer counter reaches zero, this will also initiate a maximum reset to recover from a runawaycondition. The watchdog timeout reset condition is masked if the TIMERCTL.WDRST bit is cleared to "0".
To invoke the maximum reset via the ICEPICK module, the user can perform the following from the CodeComposer 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 emulationlogic.
– The PLL Controllers are reset thereby, switching back to PLL Bypass Mode and resetting all theirregisters to default values. Both PLL1 and PLL2 are placed in reset and lose lock.– The RESETOUT pin becomes asserted (low), indicating the device is in reset.2. After device initialization is complete, the PLL Controllers pause the system clocks for 10 cycles. At theend of these 10 cycles, the RESETOUT pin is deasserted (driven high).
At this point:– The I/O pins are controlled by the default peripherals (default peripherals are determined byPINMUX0 and PINMUX1 registers).– The clock and reset of each peripheral is determined by the default settings of the Power and SleepController (PSC).– The PLL Controllers are operating in PLL Bypass Mode.– The C64x+ begins executing from DSPBOOTADDR (determined by bootmode selection).
After the reset sequence, the boot sequence begins. Since the boot and configuration pins are not latchedwith a Max Reset, the previous values (as shown in the BOOTCFG register) are used to select the bootmode. For more details on the boot sequence, see the Using the TMS320DM643x Bootloader ApplicationReport (literature number SPRAAG0 ).
After the boot sequence, follow the software initialization sequence described in Section 3.8 ,DeviceInitialization Sequence After Reset.

The C64x+ DSP CPU has an internal reset input that allows a host (PCI/HPI) to control it. This reset isconfigured through a register bit (MDCTL[39]. LRST) in the Power Sleep Controller (PSC) module. When inC64x+ local reset, the slave DMA port on C64x+ will remain active and the internal memory will beaccessible. For procedures on asserting and de-asserting CPU local reset by the host, see theTMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978 ).
For information on peripheral selection at the rising edge of POR or RESET, see Section 3 ,DeviceConfigurations of this data manual.
The user can configure the local reset and clock state of a peripheral through programming the PSC.Table 6-4 , DM6433 LPSC Assignments identifies the LPSC numbers and the peripherals capable of beinglocally reset by the PSC. For more detailed information on the programming of these peripherals by thePSC, see the TMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978 ).
If any of the above reset sources occur simultaneously, the PLLC only processes the highest priority resetrequest. The reset request priorities are as follows (high to low):•Power-on Reset•Maximum Reset•Warm Reset•CPU Reset
The Reset Type Status (RSTYPE) register (01C4 00E4) is the only register for the reset controller. Thisregister falls in the same memory range as the PLL1 controller registers (see Table 6-18 for the PLL1Controller Registers (including Reset Controller)). For more details on the RSTYPE register, see theTMS320DM643x DMP DSP Subsystem Reference Guide (literature number SPRU978 ).
During normal operations, pins are controlled by the respective peripheral selected in the PINMUX0 orPINMUX1 register. During device level global reset, the pin behaves as follows:
Multiplexed Boot and Configuration Pins
These pins are forced 3-stated when RESETOUT is asserted (low). This is to ensure the proper boot andconfiguration values can be latched on these multiplexed pins. This is particularly useful in the case wherethe boot and configuration values are driven by an external control device. After RESETOUT isdeasserted (high), these pins are controlled by their respective default peripheral.•Boot and Configuration Pins Group: YOUT6/GP[28], YOUT5/GP[27], YOUT4/GP[26]/(FASTBOOT),YOUT3/GP[25]/(BOOTMODE3), YOUT2/GP[24]/(BOOTMODE2), YOUT1/GP[23]/(BOOTMODE1),YOUT0/GP[22]/(BOOTMODE0), R0/EM_A[4]/GP[10]/(AEAW2/PLLMS2),

Default Power Down Pins
As discussed in Section 3.2 ,Power Considerations, the VDD3P3V_PWDN register controls power to the3.3-V pins. The VDD3P3V_PWDN register defaults to powering down some 3.3-V pins to save power. Formore details on the VDD3P3V_PWDN register and which 3.3-V pins default to powerup or powerdown,Section 3.2 ,Power Considerations. The pins that default to powerdown, are both reset to powerdown andhigh-impedance. They remain in that state until configured otherwise by VDD3P3_PWDN andPINMUX0/PINMUX1 programming.•Default Power Down Pin Group: GP[4]/PWM1, ACLKR0/CLKX0/GP[99], AFSR0/DR0/GP[100],AHCLKR0/CLKR0/GP[101], AXR0[3]/FSR0/GP[102], AXR0[2]/FSX0/GP[103], AXR0[1]/DX0/GP[104],AXR0/GP[105], ACLKX0/GP[106], AFSX0/GP[107], AHCLKX0/GP[108], AMUTEIN0/GP[109],AMUTE0/GP[110], TOUT1L/GP[55], TINP1L/GP[56], CLKS0/TOUT0L/GP[97], TINP0L/GP[98],URXD0/GP[85], UTXD0/GP[86], UCTS0/GP[87], and URTS0/PWM0/GP[88].
All Other Pins
During RESETOUT assertion (low), all other pins are controlled by the default peripheral. The defaultperipheral is determined by the default settings of the PINMUX0 or PINMUX1 registers.
Some of the PINMUX0/PINMUX1 settings are determined by configuration pins latched at reset. Todetermine the reset behavior of these pins, see Section 3.7 ,Multiplexed Pin Configurations and read therest of the this subsection to understand how that default peripheral controls the pin.
The reset behaviors for all these other pins are categorized as follows (also see Figure 6-7 and Figure 6-8in Section 6.5.9 ,Reset Electrical Data/Timing):•Z+/Low Group (Z Longer-to-Low Group): These pins are 3-stated when device-level global resetsource (e.g., POR, RESET, or Max Reset) is asserted. These pins remain 3-stated throughoutRESETOUT assertion. When RESETOUT is deasserted, these pins drive a logic low.•Z+/High Group (Z Longer-to-High Group): These pins are 3-stated when device-level global resetsource (e.g., POR, RESET, or Max Reset) is asserted. These pins remain 3-stated throughoutRESETOUT assertion. When RESETOUT is deasserted, these pins drive a logic high.•Z+/Invalid Group (Z Longer-to-Invalid Group): These pins are 3-stated when device-level globalreset source (e.g., POR, RESET, or Max Reset) is asserted. These pins remain 3-stated throughoutRESETOUT assertion. When RESETOUT is deasserted, these pins drive an invalid value untilconfigured otherwise by their respective peripheral (after the peripheral is enabled by the PSC).•Z Group: These pins are 3-stated by default, and these pins remain 3-stated throughout RESETOUTassertion. When RESETOUT is deasserted, these pins remain 3-stated until configured otherwise bytheir respective peripheral (after the peripheral is enabled by the PSC).•Low Group: These pins are low by default, and remain low until configured otherwise by theirrespective peripheral (after the peripheral is enabled by the PSC).•High Group: These pins are high by default, and remain high until configured otherwise by theirrespective peripheral (after the peripheral is enabled by the PSC).•Z/Low Group (Z-to-Low Group): These pins are 3-stated when device-level global reset source (e.g.,POR, RESET, or Max Reset) is asserted. When the reset source is deasserted, these pins drive alogic low.•Z/High Group (Z-to-High Group): These pins are 3-stated when device-level global reset source(e.g., POR, RESET, or Max Reset) is asserted. When reset source is deasserted, these pins drive alogic high.•Clock Group: These clock pins are toggling by default. They paused momentarily before RESETOUTis deasserted (high). The only pin in the Clock Group is CLKOUT0.
This is a list of possible default peripherals and how they control the pins during reset:•GPIO: All GPIO pins behave according to Z Group.Note: The following EMIFA list only includes pins that can default to function as EMIFA signals.•EMIFA: These EMIFA signals are multiplexed with boot and configuration pins: EM_A[4], EM_A[2:0],

The DM6433 device includes two options to provide an external clock input:•Use an on-chip oscillator with external crystal.•Use an external 1.8-V LVCMOS-compatible clock input.
The optimal external clock input frequency is 27 MHz. Section 6.6.1 provides more details on Option 1,using an on-chip oscillator with external crystal. Section 6.6.2 provides details on Option 2, using anexternal 1.8-V LVCMOS-compatible clock input.
In this option, a crystal is used as the external clock input to the DM6433.
The 27-MHz oscillator provides the reference clock for all DM6433 subsystems and peripherals. Theon-chip oscillator requires an external 27-MHz crystal connected across the MXI and MXO pins, alongwith two load capacitors, as shown in Figure 6-9 . The external crystal load capacitors must be connectedonly to the 27-MHz oscillator ground pin (MXV
SS
). Do not connect to board ground (V
SS
). The MXV
DD
pincan be connected to the same 1.8 V power supply as DV
DDR2
.

The load capacitors, C1 and C2, should be chosen such that the equation is satisfied (typical values areC1 = C2 = 10 pF). C
L
in the equation is the load specified by the crystal manufacturer. All discretecomponents used to implement the oscillator circuit should be placed as close as possible to theassociated oscillator pins (MXI and MXO) and to the MXV

pin.

There are two independently controlled PLLs on DM6433. PLL1 generates the frequencies required for theDSP, DMA, and other peripherals. PLL2 generates the frequencies required for the DDR2 interface andthe VPBE in certain modes. The recommended reference clock for both PLLs is the 27-MHz crystal input.
Both PLL1 and PLL2 power is supplied externally via the 1.8 V PLL power-supply pin (PLL
PWR18
). Anexternal EMI filter circuit must be added to PLL
PWR18
, as shown in Figure 6-11 . The 1.8-V supply of theEMI filter must be from the same 1.8-V power plane supplying the device’s 1.8-V I/O power-supply pins(DV
DDDR2
). TI recommends EMI filter manufacturer Murata, part number NFM18CC222R1C3.
All PLL external components (C1, C2, and the EMI Filter) must be placed as close to the device aspossible. For the best performance, TI recommends that all the PLL external components be on a singleside of the board without jumpers, switches, or components other than the ones shown in Figure 6-11 . Forreduced PLL jitter, maximize the spacing between switching signals and the PLL external components(C1, C2, and the EMI Filter).
Figure 6-11. PLL1 and PLL2 External Connection
The minimum CLKIN rise and fall times should also be observed. For the input clock timing requirements,see Section 6.7.4 ,Clock PLL Electrical Data/Timing (Input and Output Clocks).
There is an allowable range for PLL multiplier (PLLM). There is a minimum and maximum operatingfrequency for MXI/CLKIN, PLLOUT, and the device clocks (SYSCLKs). The PLL Controllers must beconfigured not to exceed any of these constraints documented in this section (certain combinations ofexternal clock inputs, internal dividers, and PLL multiply ratios might not be supported).

(1) MXI/CLKIN input clock is used for both PLL Controllers (PLLC1 and PLLC2).
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 tobecome stable after the PLL is powered up (after PLLCTL.PLLPWRDN bit goes through a 1-to-0transition). The PLL should not be operated until this stabilization time has expired. This stabilization stepmust be applied after these resets—a Power-on Reset, a Warm Reset, or a Max Reset, as thePLLCTL.PLLPWRDN bit resets to a "1". For the PLL stabliziation time value, see Table 6-17 .
The PLL reset time is the amount of wait time needed for the PLL to properly reset (writing PLLRST = 0)before bringing the PLL out of reset (writing PLLRST = 1). For the PLL reset time value, see Table 6-17 .
The PLL lock time is the amount of time needed from when the PLL is taken out of reset (PLLRST = 1with PLLEN = 0) to when to when the PLL controller can be switched to PLL mode (PLLEN = 1). For thePLL lock time value, see Table 6-17 .

Digital Media Processor
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
www.ti.com
If the internal oscillator is bypassed, to minimize the clock jitter a single clean power supply should powerboth the DM6433 device and the external clock oscillator circuit. The minimum CLKIN rise and fall timesshould also be observed. For the input clock timing requirements, see Section 6.7.4 ,Clock PLL ElectricalData/Timing (Input and Output Clocks).
Rise/fall times, duty cycles (high/low pulse durations), and the load capacitance of the external clocksource must meet the device requirements in this data manual (see Section 5.3 ,Electrical CharacteristicsOver Recommended Ranges of Supply Voltage and Operating Temperature and Section 6.7.4 ,Clock PLLElectrical Data/Timing (Input and Output Clocks).

For video and audio applications, stability of the input clock is veryimportant. The user should select a clock with low enough ppm to ensure good video and audio quality for the specific application. If theVPBE is used for NTSC or PAL compliant video output, TI recommends a 27-MHz, 50-ppm clock. For more details on this NTSC andPAL compliant output video, see Section 6.10.2 ,Video Processing Back-End (VPBE).

The C64x+ DSP interrupt controller combines device events into 12 prioritized interrupts. The source foreach of the 12 CPU interrupts is user programmable and is listed in Table 6-21 . Also, the interruptcontroller controls the generation of the CPU exception and emulation interrupts. The NMI input to theC64x+ DSP interrupt controller is not connected internally; therefore, the NMI interrupt is not available.Table 6-22 summarizes the C64x+ interrupt controller registers and memory locations. For more details onDSP interrupt controller, see the TMS320DM643x DMP DSP Subsystem Reference Guide (literaturenumber SPRU978 ).

Figure 6-16 and Figure 6-17 describe EMIF transactions that include extended wait states inserted during the STROBEphase. However, cycles inserted as part of this extended wait period should not be counted; the 4E requirement is to the start of wherethe HOLD phase would begin if there were no extended wait cycles.

The Video Processing Back-End (VPBE) consists of the On-Screen Display (OSD) module, the VideoEncoder (VENC) including the Digital LCD (DLCD) and Analog (i.e., DAC) interfaces. The video encodergenerates analog video output. The DLCD controller generates digital RGB/YCbCr data output and timingsignals.
The VPBE register memory mapping is shown in Table 6-31 .

To ensure NTSC and PAL compliant output video, the stability of the input clock source is very important.TI recommends a 27-MHz, 50-ppm crystal. Ceramic oscillators are not recommended. The NTSC/PALcolor sub-carrier frequency is derived from the 27-MHz clock; therefore, if the 27-MHz clock drifts, then thecolor sub-carrier frequency will drift as well. Assuming no 27-MHz frequency drift, the color sub-carrierfrequency is generated as follows:
To ensure the color sub-carrier frequency will not drift out of specification, the user must follow the crystalrequirements discussed in Section 6.6.1 , Clock Input Option 1—Crystal. Alternatively, if the VPBE inputclock is sourced from the VPBECLK, this clock must have a frequency stability of ±50 ppm to ensureNTSC and PAL compliant output video.
The major function of the OSD module is to gather and blend video data and display/bitmap data beforefeeding it to the Video Encoder (VENC) in YCbCr format. The video and display data is read from anexternal memory, typically DDR2. The OSD is programmed via control and parameter registers. Thefollowing are the primary features that are supported by the OSD.•Simultaneous display of two video windows and two OSD windows (VIDWIN0/VIDWIN1 andOSDWIN0/OSDWIN1).
– Separate enable for each window– Programmable width, height, and base starting coordinates for each window– External memory address and offset registers for each window– Support for x2 and x4 zoom in both the horizontal and vertical direction– OSDWIN1 can be used as an attribute window for OSDWIN0– Attribute window blinking intervals– Field/frame mode for the windows (interlaced/progressive)– Eight step blending process between the OSD and video windows– Transparency support for the OSD and video data (when a bitmap pixel is zero, there will be noblending for that corresponding video pixel)– Resize from VGA to NTSC/PAL (640x480 to 720x576) for both the OSD and video windows– Reads in YCbCr data in 4:2:2 format from external memory, with the capability for swapping theorder of the CbCr component in the 32-bit word (this is relevant to the two video windows)– Support for a ping-pong buffer scheme that can be used for VIDWIN0 (allows for video data to beaccessed from two different locations in DDR2)– Each OSD window (either one, but not both at the same time) is capable of reading in RGB data

(16-bit data with six bits for the green and five bits each for the red and blue colors) instead ofbitmap data in YCbCr format restricted to a maximum of 8-bits– The OSD bitmap data width is selectable between 1, 2, 4, or 8-bits.– Each OSD window supports 16 entries for the bitmap (to index into a 256 entry RAM/ROM CLUTtable).
– Indirect support for 24-bit RGB input data (which will be transformed into 16-bit YCbCr videowindow data) via the wrapper interface in the VPBE.•Support for a rectangular cursor window and a programmable background color selection.– Programmable color palette with the ability to select between a RAM/ROM table with support for256 colors.– The width, height, and color of the cursor is programmable.– The display priority is: Rectangular-Cursor > OSDWIN1 > OSDWIN0 > VIDWIN1 > VIDWIN0 >background color•Support for attenuation of the YCbCr values for the REC601 standard.
The following restrictions exist in the OSD module.•Both the OSD windows and VIDWIN1 should be fully contained inside VIDWIN0.•When one of the OSD windows is set in RGB mode, it cannot overlap with VIDWIN1.•The OSD cannot support more than 256 color entries in the CLUT RAM/ROM. Some applicationsrequire higher number of entries, and one workaround is to use VIDWIN1 as an overlay mimicking theOSD window. Another option is to use the RGB mode for one of the OSD windows which allows for atotal of 16-bits for the R, G, and B colors (64K colors).•The OSD can only read YCbCr in 4:2:2 interleaved format for the video windows. Other formats, eithercolor separate storage or 4:4:4/4:2:0 interleaved data is not supported.•If the vertical resize filter is enabled for either of the video windows, the maximum horizontal windowdimension cannot be greater than 720 currently.•It is not possible to use both of the CLUT ROMs at the same time. However, one window can useRAM while another uses ROM.•The 24-bit RGB input mode is only valid for one of the two video windows (programmable) and doesnot apply to the OSD windows.

The DM6433's analog video DAC outputs are designed to drive a 500- Ωload. Figure 6-23 describes atypical circuit that will permit connecting the analog video output from the DM6433 device to standard75- Ωimpedance video systems. Another solution is to use a Video Amplifier, such as the TexasInstruments' OPA361, which provides a complete solution to the typical output circuit shown inFigure 6-23 .

A. HSTROBE refers to the following logical operation on HCS, HDS1, and HDS2: [NOT(HDS1 XOR HDS2)] OR HCS.
B. Depending on the type of write or read operation (HPID without auto-incrementing; HPIA, HPIC, or HPID with
auto-incrementing) and the state of the FIFO, transitions on HRDY may or may not occur.
For more detailed information on the HPI peripheral, see the TMS320DM643x Host Port Interface (HPI) User ’s Guide
(literature number SPRU998).
C. HCS reflects typical HCS behavior when HSTROBE assertion is caused by HDS1 or HDS2. HCS timing requirements are
reflected by parameters for HSTROBE.
DFor proper HPI operation, HAS must be pulled up via an external resistor.

Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The McBSP provides these functions:•Full-duplex communication•Double-buffered data registers, which allow a continuous data stream•Independent framing and clocking for receive and transmit•Direct interface to industry-standard codecs, analog interface chips (AICs), and other seriallyconnected analog-to-digital (A/D) and digital-to-analog (D/A) devices•External shift clock or an internal, programmable frequency shift clock for data transfer
If internal clock source is used, the CLKGDV field of the Sample Rate Generator Register (SRGR) mustalways be set to a value of 1 or greater.
For more detailed information on the McBSP peripheral, see the TMS320DM643x DMP MultichannelBuffered Serial Port (McBSP) User's Guide (literature number SPRU943 ).

(1) CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are alsoinverted.
(2) P = SYSCLK3 period in ns. For example, when running parts at 600 MHz, use P = 10 ns.(3) Use whichever value is greater. Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clocksource. The minimum CLKR/X cycle times are based on internal logic speed; the maximum usable speed may be lower due to EDMAlimitations and AC timing requirements.(4) This parameter applies to the maximum McBSP frequency. Operate serial clocks (CLKR/X) in the reasonable range of 40/60 duty cycle.

6.15 Multichannel Audio Serial Port (McASP0) Peripheral
6.15.1 McASP0 Device-Specific Information
TMS320DM6433
Digital Media Processor
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
www.ti.com
The McASP functions as a general-purpose audio serial port optimized for the needs of multichannelaudio applications. The McASP is useful for time-division multiplexed (TDM) stream, Inter-IntegratedSound (I2S) protocols, and intercomponent digital audio interface transmission (DIT).
The DM6433 device includes one multichannel audio serial port (McASP) interface peripheral (McASP0).The McASP0 is a serial port optimized for the needs of multichannel audio applications.
The McASP0 consists of a transmit and receive section. These sections can operate completelyindependently with different data formats, separate master clocks, bit clocks, and frame syncs oralternatively, the transmit and receive sections may be synchronized. The McASP module also includes apool of 16 shift registers that may be configured to operate as either transmit data or receive data.
The transmit section of the McASP 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 forS/PDIF, AES-3, IEC-60958, CP-430 transmission. The receive section of the McASP supports the TDMsynchronous serial format.
The McASP can support one transmit data format (either a TDM format or DIT format) and one receiveformat at a time. All transmit shift registers use the same format and all receive shift registers use thesame 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 fornon-audio data (for example, passing control information between two DSPs).
The McASP peripheral has additional capability for flexible clock generation, and error detection/handling,as well as error management.
For more detailed information on and the functionality of the McASP0 peripheral, see the TMS320DM643xDMP Multichannel Audio Serial Port (McASP) User's Guide (literature number SPRU980).

6.16 Ethernet Media Access Controller (EMAC)
6.16.1 EMAC Peripheral Register Description(s)
TMS320DM6433
Digital Media Processor
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
www.ti.com
The Ethernet Media Access Controller (EMAC) provides an efficient interface between DM6433 and thenetwork. The DM6433 EMAC supports both 10Base-T (10 Mbits/second [Mbps]) and 100Base-TX (100Mbps) in either half- or full-duplex mode. The EMAC module also supports hardware flow control andquality of service (QOS) support.
The EMAC controls the flow of packet data from the DM6433 device to the PHY. The MDIO modulecontrols PHY configuration and status monitoring.
The EMAC module conforms to the IEEE 802.3-2002 standard, describing the “Carrier Sense MultipleAccess with Collision Detection (CSMA/CD) Access Method and Physical Layer” specifications. The IEEE802.3 standard has also been adopted by ISO/IEC and re-designated as ISO/IEC 8802-3:2000(E).
Deviation 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 willintentionally generate an incorrect checksum by inverting the frame CRC, so that the transmitted framewill be detected as an error by the network.
Both the EMAC and the MDIO modules interface to the DM6433 device through a custom interface thatallows efficient data transmission and reception. This custom interface is referred to as the EMAC controlmodule, and is considered integral to the EMAC/MDIO peripheral. The control module is also used tomultiplex and control interrupts.
For the DM6433 Ethernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO)Module User's Guide (literature number SPRU941) which describes the DM6433 EMAC peripheral indetail, see Section 2.9 ,Documentation Support section . For a list of supported registers and registerfields, see Table 6-65 [Ethernet MAC (EMAC) Control Registers] and Table 6-66 [EMAC StatisticsRegisters] in this data manual.

TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order toenumerate all PHY devices in the system.
The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface tointerrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIOmodule to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve thenegotiation results, and configure required parameters in the EMAC module for correct operation. Themodule is designed to allow almost transparent operation of the MDIO interface, with very littlemaintenance from the core processor. Only one PHY may be connected at any given time.
For more detailed information on the MDIO peripheral, see the Documentation Support section for theEthernet Media Access Controller (EMAC)/Management Data Input/Output (MDIO) Module ReferenceGuide. For a list of supported registers and register fields, see Table 6-73 [MDIO Registers] in this datamanual.

SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The DM6433 DMP supports connections to PCI-compliant devices via the integrated PCI master/slave businterface. The PCI port interfaces to DSP internal resources via the data switched central resource. Thedata 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 DMPPeripheral Component Interconnect (PCI) User's Guide (literature number SPRU985).
The PCI peripheral can act both as a PCI bus master and as a target. It supports PCI bus operation ofspeeds up to 33 MHz and uses a 32-bit data/address bus.
On the DM6433 device, the pins of the PCI peripheral are multiplexed with the pins of the VPSS, EMIFA,GPIO, HPI, VLYNQ, and EMAC peripherals. For more detailed information on how to select PCI, seeSection 3 , Device Configurations.
The DM6433 device provides an initialization mechanism through which the default values for some of thePCI configuration registers can be read from an I2C EEPROM. Table 6-81 shows the registers which canbe initialized through the PCI auto-initialization. The default value of these registers when PCIauto-initialization is not used is also shown in Table 6-81 . PCI auto-initialization is enabled by selectingPCI boot with auto-initialization. For information on how to select PCI boot with auto-initialization, seeSection 3.4.1 , Boot Modes. For more information on PCI auto-initialization, see the TMS320DM643x DMPPeripheral Component Interconnect (PCI) User's Guide (literature number SPRU985 ) and the Using theTMS320DM643x Bootloader Application Report (literature number SPRAAG0 ).
The PCI peripheral is a master peripheral within the DM6433 DMP.

6.22 General-Purpose Input/Output (GPIO)
TMS320DM6433
Digital Media Processor
www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs.When configured as an output, a write to an internal register can control the state driven on the output pin.When configured as an input, the state of the input is detectable by reading the state of an internalregister. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in differentinterrupt/event generation modes. The GPIO peripheral provides generic connections to external devices.The GPIO pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of GP[0:15]).
The DM6433 GPIO peripheral supports the following:•Up to 111 3.3-V GPIO pins, GP[0:110]•Interrupts:
– Up to 8 unique GP[0:7] interrupts from Bank 0– 7 GPIO bank (aggregated) interrupt signals from each of the 7 banks of GPIOs– Interrupts can be triggered by rising and/or falling edge, specified for each interrupt capable GPIOsignal•DMA events:
– Up to 8 unique GPIO DMA events from Bank 0– 7 GPIO bank (aggregated) DMA event signals from each of the 7 banks of GPIOs•Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIOsignal(s). This allows multiple firmware processes to toggle GPIO output signals without critical sectionprotection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching toanther process during GPIO programming).•Separate Input/Output registers•Output register in addition to set/clear so that, if preferred by firmware, some GPIO output signals canbe toggled by direct write to the output register(s).•Output register, when read, reflects output drive status. This, in addition to the input register reflectingpin status and open-drain I/O cell, allows wired logic be implemented.
The memory map for the GPIO registers is shown in Table 6-95 . For more detailed information on GPIOs,see the TMS320DM643x DMP General-Purpose Input/Output (GPIO) User's Guide (literature numberSPRU988 ).

www.ti.com
SPRS343C – NOVEMBER 2006 – REVISED JUNE 2008
The JTAG
(3)
interface is used for BSDL testing and emulation of the DM6433 device.
TRST only needs to be released when it is necessary to use a JTAG controller to debug the device orexercise the device's boundary scan functionality. Note: TRST is synchronous and must be clocked byTCK; otherwise, the boundary scan logic may not respond as expected after TRST is asserted.
For maximum reliability, DM6433 includes an internal pulldown (IPD) on the TRST pin to ensure thatTRST will always be asserted upon power up and the device's internal emulation logic will always beproperly initialized.
JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAGcontrollers 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 externallydrive TRST high before attempting any emulation or boundary scan operations.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
