The C6713 and C6713B devices are based on the high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making this DSP an excellent choice for multichannel and multifunction applications. Operating at 225 MHz, the C6713/13B delivers up to 1350 million floating-point operations per second (MFLOPS), 1800 million instructions per second (MIPS), and with dual fixed-/floating-point multipliers up to 450 million multiply-accumulate operations per second (MMACS). Operating at 300 MHz, the C6713B delivers up to 1800 million floating-point operations per second (MFLOPS), 2400 million instructions per second (MIPS), and with dual fixed-/floating-point multipliers up to 600 million multiply-accumulate operations per second (MMACS). The C6713/13B uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The Level 1 program cache (L1P) is a 4K-Byte direct-mapped cache and the Level 1 data cache (L1D) is a 4K-Byte 2-way set-associative cache. The Level 2 memory/cache (L2) consists of a 256K-Byte memory space that is shared between program and data space. 64K Bytes of the 256K Bytes in L2 memory can be configured as mapped memory, cache, or combinations of the two. The remaining 192K Bytes in L2 serves as mapped SRAM. The C6713/13B has a rich peripheral set that includes two Multichannel Audio Serial Ports (McASPs), two Multichannel Buffered Serial Ports (McBSPs), two Inter-Integrated Circuit (I2C) buses, one dedicated General-Purpose Input/Output (GPIO) module, two general-purpose timers, a host-port interface (HPI), and a glueless external memory interface (EMIF) capable of interfacing to SDRAM, SBSRAM, and asynchronous peripherals. The two McASP interface modules each support one transmit and one receive clock zone. Each of the McASP has eight serial data pins which can be individually allocated to any of the two zones. The serial port supports time-division multiplexing on each pin from 2 to 32 time slots. The C6713/13B has sufficient bandwidth to support all 16 serial data pins transmitting a 192 kHz stereo signal. Serial data in each zone may be transmitted and received on multiple serial data pins simultaneously and formatted in a multitude of variations on the Philips Inter-IC Sound (I2S) format. In addition, the McASP transmitter may be programmed to output multiple S/PDIF, IEC60958, AES-3, CP-430 encoded data channels simultaneously, with a single RAM containing the full implementation of user data and channel status fields. The McASP also provides extensive error-checking and recovery features, such as the bad clock detection circuit for each high-frequency master clock which verifies that the master clock is within a programmed frequency range. The two I2C ports on the TMS320C6713/13B allow the DSP to easily control peripheral devices and communicate with a host processor. In addition, the standard multichannel buffered serial port (McBSP) may be used to communicate with serial peripheral interface (SPI) mode peripheral devices. The TMS320C6713/13B device has two bootmodes: from the HPI or from external asynchronous ROM. For more detailed information, see the bootmode section of this data sheet. The TMS320C67x DSP generation is supported by the TI eXpressDSPt set of industry benchmark development tools, including a highly optimizing C/C++ Compiler, the Code Composer Studiot Integrated Development Environment (IDE), JTAG-based emulation and real-time debugging, and the DSP/BIOSt kernel.

The CPU fetches advanced very-long instruction words (VLIW) (256 bits wide) to supply up to eight 32-bit instructions to the eight functional units during every clock cycle. The VLIW architecture features controls by which all eight units do not have to be supplied with instructions if they are not ready to execute. The first bit of every 32-bit instruction determines if the next instruction belongs to the same execute packet as the previous instruction, or whether it should be executed in the following clock as a part of the next execute packet. Fetch packets are always 256 bits wide; however, the execute packets can vary in size. The variable-length execute packets are a key memory-saving feature, distinguishing the C67x CPU from other VLIW architectures. The CPU features two sets of functional units. Each set contains four units and a register file. One set contains functional units .L1, .S1, .M1, and .D1; the other set contains units .D2, .M2, .S2, and .L2. The two register files each contain 16 32-bit registers for a total of 32 general-purpose registers. The two sets of functional units, along with two register files, compose sides A and B of the CPU (see the functional block and CPU diagram and Figure 1). The four functional units on each side of the CPU can freely share the 16 registers belonging to that side. Additionally, each side features a single data bus connected to all the registers on the other side, by which the two sets of functional units can access data from the register files on the opposite side. While register access by functional units on the same side of the CPU as the register file can service all the units in a single clock cycle, register access using the register file across the CPU supports one read and one write per cycle. The C67x CPU executes all C62x instructions. In addition to C62x fixed-point instructions, the six out of eight functional units (.L1, .S1, .M1, .M2, .S2, and .L2) also execute floating-point instructions. The remaining two functional units (.D1 and .D2) also execute the new LDDW instruction which loads 64 bits per CPU side for a total of 128 bits per cycle. Another key feature of the C67x CPU is the load/store architecture, where all instructions operate on registers (as opposed to data in memory). Two sets of data-addressing units (.D1 and .D2) are responsible for all data transfers between the register files and the memory. The data address driven by the .D units allows data addresses generated from one register file to be used to load or store data to or from the other register file. The C67x CPU supports a variety of indirect addressing modes using either linear- or circular-addressing modes with 5- or 15-bit offsets. All instructions are conditional, and most can access any one of the 32 registers. Some registers, however, are singled out to support specific addressing or to hold the condition for conditional instructions (if the condition is not automatically “true”). The two .M functional units are dedicated for multiplies. The two .S and .L functional units perform a general set of arithmetic, logical, and branch functions with results available every clock cycle. The processing flow begins when a 256-bit-wide instruction fetch packet is fetched from a program memory. The 32-bit instructions destined for the individual functional units are “linked” together by “1” bits in the least significant bit (LSB) position of the instructions. The instructions that are “chained” together for simultaneous execution (up to eight in total) compose an execute packet. A “0” in the LSB of an instruction breaks the chain, effectively placing the instructions that follow it in the next execute packet. If an execute packet crosses the fetch-packet boundary (256 bits wide), the assembler places it in the next fetch packet, while the remainder of the current fetch packet is padded with NOP instructions. The number of execute packets within a fetch packet can vary from one to eight. Execute packets are dispatched to their respective functional units at the rate of one per clock cycle and the next 256-bit fetch packet is not fetched until all the execute packets from the current fetch packet have been dispatched. After decoding, the instructions simultaneously drive all active functional units for a maximum execution rate of eight instructions every clock cycle. While most results are stored in 32-bit registers, they can be subsequently moved to memory as bytes or half-words as well. All load and store instructions are byte-, half-word, or word-addressable.

Although internal pullup resistors exist on these pins, providing external connectivity adds convenience to the user in debugging and flexibility in switching operating modes. Internal pullup/pulldown resistors also exist on the non-configuration pins on the HPI data bus (HD[15, 13:9, 7:5, 2:0] (for 13) and HD[15, 13, 11:9, 7:5, 2:0] (for 13B)). For proper device operation of the HD[15, 13:9, 7, 1, 0] (for13) or HD[13, 11:9, 7, 1, 0] (for 13B), do not oppose the internal pullup/pulldown resistors on these non-configuration pins with external pullup/pulldown resistors. If an external controller provides signals to these HD[15, 13:9, 7, 1, 0] (for 13) or HD[13, 11:9, 7, 1, 0] (for 13B) non-configuration pins, these signals must be driven to the default state of the pins at reset, or not be driven at all. However, the HD[6, 5, 2] (for 13) or HD[15, 6, 5, 2] (for 13B) non-configuration pins can be opposed and driven during reset.

Each TMS320 DSP commercial family member has one of three prefixes: TMX, TMP, or TMS. Texas Instruments recommends two of three possible prefix designators for support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development from engineering prototypes (TMX / TMDX) through fully qualified production devices/tools (TMS / TMDS). Device development evolutionary flow: TMX Experimental device that is not necessarily representative of the final device’s electrical specifications TMP Final silicon die that conforms to the device’s electrical specifications but has not completed quality and reliability verification TMS Fully qualified production device Support tool development evolutionary flow: TMDX Development-support product that has not yet completed Texas Instruments internal qualification testing. TMDS Fully qualified development-support product TMX and TMP devices and TMDX development-support tools are shipped with appropriate disclaimers describing their limitations and intended uses. Experimental devices (TMX) may not be representative of a final product and Texas Instruments reserves the right to change or discontinue these products without notice. TMS devices and TMDS development-support tools have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI’s standard warranty applies. Predictions show that prototype devices (TMX or TMP) have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used. TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for example, GDP), the temperature range (for example, blank is the default commercial temperature range), and the device speed range in megahertz (for example, -225 is 225 MHz). Figure 12 provides a legend for reading the complete device name for any TMS320C6000 DSP family member. TMS320 is a trademark of Texas Instruments.

A “P” bit (CCFG.31) allows the programmer to select the priority of accesses to L2 memory originating from the transfer crossbar (TC) over accesses originating from the L1D memory system. An important class of TC accesses is EDMA transfers, which move data to or from the L2 memory. While the EDMA normally has no issue accessing L2 memory due to the high hit rates on the L1D memory system, there are pathological cases where certain CPU behavior could block the EDMA from accessing the L2 memory for long enough to cause a missed deadline when transferring data to a peripheral such as the McASP or McBSP. This can be avoided by setting the P bit to “1” because the EDMA will assume a higher priority than the L1D memory system when accessing L2 memory. For more detailed information on the P-bit function and for silicon advisories concerning EDMA L2 memory accesses blocked, see the TMS320C6713, TMS320C6713B Digital Signal Processors Silicon Errata (literature number SPRZ191). 31 30 P† R/W-0 10 7 9 8 3 2 Reserved IP ID Reserved L2MODE R-x W-0 W-0 R-0 0000 R/W-000 Legend: R = Readable; R/W = Readable/Writeable; -n = value after reset; -x = undefined value after reset † Unlike the C6713 device, the C6713B device includes a P bit.

The highest priority interrupt is INT_00 (dedicated to RESET) while the lowest priority is INT_15. The first four interrupts are non-maskable and fixed. The remaining interrupts (4−15) are maskable and default to the interrupt source listed in Table 27. However, their interrupt source may be reprogrammed to any one of the sources listed in Table 28 (Interrupt Selector). Table 28 lists the selector value corresponding to each of the alternate interrupt sources. The selector choice for interrupts 4−15 is made by programming the corresponding fields (listed in Table 27) in the MUXH (address 0x019C0000) and MUXL (address 0x019C0004) registers.

These pins can be used as edge-sensitive EXT_INTx with polarity controlled by the External Interrupt Polarity Register (EXTPOL.[3:0]). The corresponding pins must first be enabled in the GPIO module by setting the corresponding enable bits in the GP Enable Register (GPEN.[7:4]), and configuring them as inputs in the GP Direction Register (GPDIR.[7:4]). These interrupts can be controlled through the GPIO module in addition to the simple EXTPOL.[3:0] bits.

Four of the sixteen channels (channels 8−11) are reserved for EDMA chaining, leaving 12 EDMA channels available to service peripheral devices. The EDMA selector registers that control the EDMA channels servicing peripheral devices are located at addresses 0x01A0FF00 (ESEL0), 0x01A0FF04 (ESEL1), and 0x01A0FF0C (ESEL3). These EDMA selector registers control the mapping of the EDMA events to the EDMA channels. Each EDMA event has an assigned EDMA selector code (see Table 31). By loading each EVTSELx register field with an EDMA selector code, users can map any desired EDMA event to any specified EDMA channel. Table 30 lists the default EDMA selector value for each EDMA channel.

For the PLL Reset Time value, see Table 34. The PLL Lock Time is the amount of time from when PLLRST = 0 with PLLEN = 0 (PLL out of reset, but still bypassed) to when the PLLEN bit can be safely changed to “1” (switching from bypass to the PLL path), see Table 34 and Figure 15. Under some operating conditions, the maximum PLL Lock Time may vary from the specified typical value. For the PLL Lock Time values, see Table 34. Table 34. PLL Lock and Reset Times MIN PLL Lock Time PLL Reset Time TYP MAX UNIT 75 187.5 µs 125 ns Table 35 shows the C6713/13B device’s CLKOUT signals, how they are derived and by what register control bits, and what is the default settings.

The input clock (CLKIN) may also be divided down by a programmable divider OSCDIV1 (/1, /2, /3, ..., /32) and output on the CLKOUT3 pin for other use in the system. Figure 15 shows that the input clock source may be divided down by divider PLLDIV0 (/1, /2, ..., /32) and then multiplied up by a factor of x4, x5, x6, and so on, up to x25. Either the input clock (PLLEN = 0) or the PLL output (PLLEN = 1) then serves as the high-frequency reference clock for the rest of the DSP system. The DSP core clock, the peripheral bus clock, and the EMIF clock may be divided down from this high-frequency clock (each with a unique divider) . For example, with a 30 MHz input if the PLL output is configured for 450 MHz, the DSP core may be operated at 225 MHz (/2) while the EMIF may be configured to operate at a rate of 75 MHz (/6). Note that there is a specific minimum and maximum reference clock (PLLREF) and output clock (PLLOUT) for the block labeled PLL in Figure 15, as well as for the DSP core, peripheral bus, and EMIF. The clock generator must not be configured to exceed any of these constraints (certain combinations of external clock input, internal dividers, and PLL multiply ratios might not be supported). See Table 36 for the PLL clocks input and output frequency ranges. 76 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6713, TMS320C6713B FLOATING-POINT DIGITAL SIGNAL PROCESSORS SPRS186I − DECEMBER 2001 − REVISED MAY 2004 PLL and PLL controller (continued) Table 36.

The EMIF itself may be clocked by an external reference clock via the ECLKIN pin or can be generated on-chip as SYSCLK3. SYSCLK3 is derived from divider D3 off of PLLOUT (see Figure 15, PLL and Clock Generator Logic). The EMIF clock selection is programmable via the EKSRC bit in the DEVCFG register. The settings for the PLL multiplier and each of the dividers in the clock generation block may be reconfigured via software at run time. If either the input to the PLL changes due to D0, CLKMODE0, or CLKIN, or if the PLL multiplier is changed, then software must enter bypass first and stay in bypass until the PLL has had enough time to lock (see electrical specifications). For the programming procedure, see the TMS320C6000 DSP Software-Programmable Phase-Locked Loop (PLL) Controller Reference Guide (literature number SPRU233). SYSCLK2 is the internal clock source for peripheral bus control. SYSCLK2 (Divider D2) must be programmed to be half of the SYSCLK1 rate. For example, if D1 is configured to divide-by-2 mode (/2), then D2 must be programmed to divide-by-4 mode (/4). SYSCLK2 is also tied directly to CLKOUT2 pin (see Figure 15). During the programming transition of Divider D1 and Divider D2 (resulting in SYSCLK1 and SYSCLK2 output clocks, see Figure 15), the order of programming the PLLDIV1 and PLLDIV2 registers must be observed to ensure that SYSCLK2 always runs at half the SYSCLK1 rate or slower. For example, if the divider ratios of D1 and D2 are to be changed from /1, /2 (respectively) to /5, /10 (respectively) then, the PLLDIV2 register must be programmed before the PLLDIV1 register. The transition ratios become /1, /2; /1, /10; and then /5, /10. If the divider ratios of D1 and D2 are to be changed from /3, /6 to /1, /2 then, the PLLDIV1 register must be programmed before the PLLDIV2 register. The transition ratios, for this case, become /3, /6; /1, /6; and then /1, /2. The final SYSCLK2 rate must be exactly half of the SYSCLK1 rate. Note that Divider D1 and Divider D2 must always be enabled (i. e., D1EN and D2EN bits are set to “1” in the PLLDIV1 and PLLDIV2 registers). The PLL Controller registers should be modified only by the CPU or via emulation. The HPI should not be used to directly access the PLL Controller registers. For detailed information on the clock generator (PLL Controller registers) and their associated software bit descriptions, see Table 38 through Table 44.

The McASP is a serial port optimized for the needs of multi-channel audio applications. With two McASP peripherals, the TMS320C6713/13B device is capable of supporting two completely independent audio zones simultaneously. Each McASP consists of a transmit and receive section. These sections can operate completely independently with different data formats, separate master clocks, bit clocks, and frame syncs or alternatively, the transmit and receive sections may be synchronized. Each McASP module also includes a pool of 16 shift registers that may be configured to operate as either transmit data, receive data, or general-purpose I/O (GPIO). 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 for S/PDIF, AES-3, IEC-60958, CP-430 transmission. The receive section of the McASP supports the TDM synchronous serial format. Each McASP can support one transmit data format (either a TDM format or DIT format) and one receive format at a time. All transmit shift registers use the same format and all receive shift registers use the same format. However, the transmit and receive formats need not be the same. Both the transmit and receive sections of the McASP also support burst mode which is useful for non-audio data (for example, passing control information between two DSPs). The McASP peripherals have additional capability for flexible clock generation, and error detection/handling, as well as error management.

Within this transfer mode, a wide variety of serial data formats are supported, including formats compatible with devices using the Inter-Integrated Sound (IIS) protocol. TDM synchronous transfer mode is typically used when communicating between integrated circuits such as between a DSP and one or more ADC, DAC, CODEC, or S/PDIF receiver devices. In multichannel applications, it is typical to find several devices operating synchronized with each other. For example, to provide six analog outputs, three stereo DAC devices would be driven with the same bit clock and frame sync, but each stereo DAC would use a different McASP serial data pin carrying stereo data (2 TDM time slots, left and right). The TDM synchronous serial transfer mode utilizes several control signals and one or more serial data signals: D A bit clock signal (ACLKX for transmit, ACKLR for receive) D A frame sync signal (AFSX for transmit, AFSR for receive) D An (Optional) high frequency master clock (AHCLKX for transmit, AHCLKR for receive) from which the bit clock is derived D One or more serial data pins (AXR for transmit and for receive). Except for the optional high-frequency master clock, all of the signals in the TDM synchronous serial transfer mode protocol are synchronous to the bit clocks (ACLKX and ACLKR). In the TDM synchronous transfer mode, the McASP continually transmits and receives data periodically (since audio ADCs and DACs operate at a fixed-data rate). The data is organized into frames, and the beginning of a frame is marked by a frame sync pulse on the AFSX, AFSR pin. In a typical audio system, one frame is transferred per sample period. To support multiple channels, the choices are to either include more time slots per frame (and therefore operate with a higher bit clock) or to keep the bit clock period constant and use additional data pins to transfer the same number of channels. For example, a particular six-channel DAC might require three McASP serial data pins; transferring two channels of data on each serial data pin during each sample period (frame). Another similar DAC may be designed to use only a single McASP serial data pin, but clocked three times faster and transferring six channels of data per sample period. The McASP is flexible enough to support either type of DAC but a transmitter cannot be configured to do both at the same time. For multiprocessor applications, the McASP supports any number of time slots per frame (between 2 and 32), and includes the ability to “disable” transfers during specific time slots. In addition, to support of S/PDIF, AES-3, IEC-60958, CP-430 receivers chips whose natural block (McASP frame) size is 384 samples; the McASP receiver supports a 384 time slot mode. The advantage to using the 384 time slot mode is that interrupts may be generated synchronous to the S/PDIF, AES-3, IEC-60958, CP-430 receivers, for example the “last slot” interrupt. burst transfer mode The McASP also supports a burst transfer mode, which is useful for non-audio data (for example, passing control information between two DSPs). Burst transfer mode uses a synchronous serial format similar to TDM, except the frame sync is generated for each data word transferred. In addition, frame sync generation is not periodic or time-driven as in TDM mode but rather data-driven. 84 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6713, TMS320C6713B FLOATING-POINT DIGITAL SIGNAL PROCESSORS SPRS186I − DECEMBER 2001 − REVISED MAY 2004 multichannel audio serial port (McASP) peripherals (continued) supported bit stream formats for TDM and burst transfer modes The serial data pins support a wide variety of formats. In the TDM and burst synchronous modes, the data may be transmitted / received with the following options: D D D D D D D Time slots per frame: 1 (Burst/Data Driven), or 2,3...32 (TDM/Time-Driven). Time slot size: 8, 12, 16, 20, 24, 28, 32 bits per time slot Data size: 8, 12, 16, 20, 24, 28, 32 bits (must be less than or equal to time slot) Data alignment within time slot: Left- or Right-Justified Bit order: MSB or LSB first. Unused bits in time slot: Padded with 0, 1 or extended with value of another bit. Time slot delay from frame sync: 0,1, or 2 bit delay The data format can be programmed independently for transmit and receive, and for McASP0 vs. McASP1. In addition, the McASP can automatically re-align the data as processed natively by the DSP (any format on a nibble boundary) adjusting the data in hardware to any of the supported serial bit stream formats (TDM, Burst, and DIT modes). This reduces the amount of bit manipulation that the DSP must perform and simplifies software architecture. digital audio interface transmitter (DIT) transfer mode (transmitter only) The McASP transmit section may also be configured in digital audio interface transmitter (DIT) mode where it outputs data formatted for transmission over an S/PDIF, AES-3, IEC-60958, or CP-430 standard link. These standards encode the serial data such that the equivalent of ’clock’ and ’frame sync’ are embedded within the data stream. DIT transfer mode is used as an interconnect between audio components and can transfer multichannel digital audio data over a single optical or coaxial cable. From an internal DSP standpoint, the McASP operation in DIT transfer mode is similar to the two time slot TDM mode, but the data transmitted is output as a bi-phase mark encoded bit stream with preamble, channel status, user data, validity, and parity automatically stuffed into the bit stream by the McASP module. The McASP includes separate validity bits for even/odd subframes and two 384-bit register file modules to hold channel status and user data bits. DIT mode requires at minimum: D One serial data pin (if the AUXCLK is used as the reference [see the PLL and Clock Generator Logic Figure 15]) or D One serial data pin plus either the AHCLKX or ACLKX pin (if an external clock is needed). If additional serial data pins are used, each McASP may be used to transmit multiple encoded bit streams (one per pin). However, the bit streams will all be synchronized to the same clock and the user data, channel status, and validity information carried by each bit stream will be the same for all bit streams transmitted by the same McASP module. The McASP can also automatically re-align the data as processed by the DSP (any format on a nibble boundary) in DIT mode; reducing the amount of bit manipulation that the DSP must perform and simplifies software architecture. POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 85 TMS320C6713, TMS320C6713B FLOATING-POINT DIGITAL SIGNAL PROCESSORS SPRS186I − DECEMBER 2001 − REVISED MAY 2004 multichannel audio serial port (McASP) peripherals (continued) McASP flexible clock generators The McASP transmit and receive clock generators are identical. Each clock generator can accept a high-frequency master clock input (on the AHCLKX and AHCLKR pins). The transmit and receive bit clocks (on the ACLKX and ACLKR pins) can also be sourced externally or can be sourced internally by dividing down the high-frequency master clock input (programmable factor /1, /2, /3, ... /4096). The polarity of each bit clock is individually programmable. The frame sync pins are AFSX (transmit) and AFSR (receive). A typical usage for these pins is to carry the left-right clock (LRCLK) signal when transmitting and receiving stereo data. The frame sync signals are individually programmable for either internal or external generation, either bit or slot length, and either rising or falling edge polarity. Some examples of the things that a system designer can use the McASP clocking flexibility for are: D Input a high-frequency master clock (for example, 512fs of the receiver), receive with an internally D D generated bit clock ratio of /8, while transmitting with an internally generated bit clock ratio of /4 or /2. [An example application would be to receive data from a DVD at 48 kHz but output up-sampled or decoded audio at 96 kHz or 192 kHz.] Transmit/receive data based one sample rate (for example, 44.1 kHz) using McASP0 while transmitting and receiving at a different sample rate (for example, 48 kHz) on McASP1. Use the DSP’s on-board AUXCLK to supply the system clock when the input source is an A/D converter. McASP error handling and management To support the design of a robust audio system, the McASP module includes error-checking capability for the serial protocol, data underrun, and data overrun. In addition, each McASP includes a timer that continually measures the high-frequency master clock every 32-SYSCLK2 clock cycles. The timer value can be read to get a measurement of the high-frequency master clock frequency and has a min-max range setting that can raise an error flag if the high-frequency master clock goes out of a specified range. The user would read the high-frequency transmit master clock measurement (AHCLKX0 or AHCLKX1) by reading the XCNT field of the XCLKCHK register and the user would read the high-frequency receive master clock measurement (AHCLKR0 or AHCLKR1) by reading the RCNT field of the RCLKCHK register. Upon the detection of any one or more of the above errors (software selectable), or the assertion of the AMUTE_IN pin, the AMUTE output pin may be asserted to a high or low level (selectable) to immediately mute the audio output. In addition, an interrupt may be generated if enabled based on any one or more of the error sources. McASP interrupts and EDMA events The McASP transmitter and receiver sections each generate an event on every time slot. This event can be serviced by an interrupt or by the EDMA controller. When using interrupts to service the McASP, each shift register buffer has a unique address in the McASP Registers space (see Table 3). When using the EDMA to service the McASP, the McASP DATA Port space in Table 3 is accessed. In this case, the address least-significant bits are ignored. Writes to any address in this range access the transmitting buffers in order from lowest (serializer 0) to highest (serializer 15), skipping over disabled and receiving serializers. Likewise, reads from any address in this space access the receiving buffers in the same order but skip over disabled and transmitting buffers. 86 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6713, TMS320C6713B FLOATING-POINT DIGITAL SIGNAL PROCESSORS SPRS186I − DECEMBER 2001 − REVISED MAY 2004 I2C Having two I2C modules on the TMS320C6713/13B simplifies system architecture, since one module may be used by the DSP to control local peripherals ICs (DACs, ADCs, etc.) while the other may be used to communicate with other controllers in a system or to implement a user interface.

PWRD Field of the CSR Register A delay of up to nine clock cycles may occur after the instruction that sets the PWRD bits in the CSR before the PD mode takes effect. As best practice, NOPs should be padded after the PWRD bits are set in the CSR to account for this delay. If PD1 mode is terminated by a non-enabled interrupt, the program execution returns to the instruction where PD1 took effect. If PD1 mode is terminated by an enabled interrupt, the interrupt service routine will be executed first, then the program execution returns to the instruction where PD1 took effect. In the case with an enabled interrupt, the GIE bit in the CSR and the NMIE bit in the interrupt enable register (IER) must also be set in order for the interrupt service routine to execute; otherwise, execution returns to the instruction where PD1 took effect upon PD1 mode termination by an enabled interrupt. PD2 and PD3 modes can only be aborted by device reset.

During PD1, EDMA transactions can proceed between peripherals and internal memory. Wake by a device reset Output clock from PLL is halted, stopping the internal clock structure from switching and resulting in the entire chip being halted. All register and internal RAM contents are preserved. All functional I/O “freeze” in the last state when the PLL clock is turned off. Wake by a device reset Input clock to the PLL stops generating clocks. All register and internal RAM contents are preserved. All functional I/O “freeze” in the last state when the PLL clock is turned off. Following reset, the PLL needs time to re-lock, just as it does following power-up. Wake-up from PD3 takes longer than wake-up from PD2 because the PLL needs to be re-locked, just as it does following power-up. — — When entering PD2 and PD3, all functional I/O remains in the previous state. However, for peripherals which are asynchronous in nature or peripherals with an external clock source, output signals may transition in response to stimulus on the inputs. Under these conditions, peripherals will not operate according to specifications. On C6713B silicon revision 2.0 and C6713 silicon revision 1.1, the device includes a programmable PLL which allows software control of PLL bypass via the PLLEN bit in the PLLCSR register. With this enhanced functionality comes some additional considerations when entering power-down modes. The power-down modes (PD2 and PD3) function by disabling the PLL to stop clocks to the device. However, if the PLL is bypassed (PLLEN = 0), the device will still receive clocks from the external clock input (CLKIN). Therefore, bypassing the PLL makes the power-down modes PD2 and PD3 ineffective. Make sure that the PLL is enabled by writing a “1” to PLLEN bit (PLLCSR.0) before writing to either PD3 (CSR.11) or PD2 (CSR.10) to enter a power-down mode. power-supply sequencing TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However, systems should be designed to ensure that neither supply is powered up for extended periods of time (>1 second) if the other supply is below the proper operating voltage. system-level design considerations System-level design considerations, such as bus contention, may require supply sequencing to be implemented. In this case, the core supply should be powered up prior to (and powered down after), the I/O buffers. This is to ensure that the I/O buffers receive valid inputs from the core before the output buffers are powered up, thus, preventing bus contention with other chips on the board.

A Schottky diode can also be used to tie the core rail to the I/O rail (see Figure 22). I/O Supply DVDD Schottky Diode C6000 DSP Core Supply CVDD VSS GND Figure 22. Schottky Diode Diagram Core and I/O supply voltage regulators should be located close to the DSP (or DSP array) to minimize inductance and resistance in the power delivery path. Additionally, when designing for high-performance applications utilizing the C6000 platform of DSPs, the PC board should include separate power planes for core, I/O, and ground, all bypassed with high-quality low-ESL/ESR capacitors. power-supply decoupling In order to properly decouple the supply planes from system noise, place as many capacitors (caps) as possible close to the DSP. Assuming 0603 caps, the user should be able to fit a total of 60 caps — 30 for the core supply and 30 for the I/O supply. These caps need to be close (no more than 1.25 cm maximum distance) to the DSP to be effective. Physically smaller caps are better, such as 0402, but the size needs to be evaluated from a yield/manufacturing point-of-view. Parasitic inductance limits the effectiveness of the decoupling capacitors, therefore physically smaller capacitors should be used while maintaining the largest available capacitance value. As with the selection of any component, verification of capacitor availability over the product’s production lifetime needs to be considered. IEEE 1149.1 JTAG compatibility statement The TMS320C6713/13B DSP requires that both TRST and RESET resets be asserted upon power up to be properly initialized. While RESET initializes the DSP core, TRST initializes the DSP’s emulation logic. Both resets are required for proper operation. While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for the DSP to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG port interface and DSP’s emulation logic in the reset state. TRST only needs to be released when it is necessary to use a JTAG controller to debug the DSP or exercise the DSP’s boundary scan functionality. For maximum reliability, the TMS320C6713/13B DSP includes an internal pulldown (IPD) on the TRST pin to ensure that TRST will always be asserted upon power up and the DSP’s internal emulation logic will always be properly initialized. 92 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6713, TMS320C6713B FLOATING-POINT DIGITAL SIGNAL PROCESSORS SPRS186I − DECEMBER 2001 − REVISED MAY 2004 JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG controllers may not drive TRST high but expect the use of an external pullup resistor on TRST. When using this type of JTAG controller, assert TRST to initialize the DSP after powerup and externally drive TRST high before attempting any emulation or boundary scan operations. Following the release of RESET, the low-to-high transition of TRST must be “seen” to latch the state of EMU1 and EMU0. The EMU[1:0] pins configure the device for either Boundary Scan mode or Emulation mode. For more detailed information, see the terminal functions section of this data sheet. EMIF device speed The maximum EMIF speed on the C6713/13B device is 100 MHz. TI recommends utilizing I/O buffer information specification (IBIS) to analyze all AC timings to determine if the maximum EMIF speed is achievable for a given board layout. To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839). For ease of design evaluation, Table 46 contains IBIS simulation results showing the maximum EMIF-SDRAM interface speeds for the given example boards (TYPE) and SDRAM speed grades. Timing analysis should be performed to verify that all AC timings are met for the specified board layout. Other configurations are also possible, but again, timing analysis must be done to verify proper AC timings. To maintain signal integrity, serial termination resistors should be inserted into all EMIF output signal lines (see the Terminal Functions table for the EMIF output signals).

The C6713B HD12 pin (EMIF Big Endian Mode Correctness) [EMIFBE] enhancement allows the flexibility to change the EMIF data placement on the EMIF bus. When using the default setting of HD12 = 1 for the C6713B, the EMIF will present 8-bit or 16-bit data on the ED[7:0] side of the bus if using Little Endian mode (HD8 = 1) and to the ED[31:24] side of the bus if using Big Endian mode. Figure 23 shows the mapping of 16-bit and 8-bit C6713B devices.

While RESET is low, the internal reset is also asserted and the device is held in reset and is initialized to the prescribed reset state. Refer to reset timing for reset timing characteristics and states of device pins during reset. The release of the internal reset signal (see the Reset Phase 3 discussion in the Reset Timing section of this data sheet) starts the processor running with the prescribed device configuration and boot mode. The C6713/13B has three types of boot modes: D Host boot If host boot is selected, upon release of internal reset, the CPU is internally “stalled” while the remainder of the device is released. During this period, an external host can initialize the CPU’s memory space as necessary through the host interface, including internal configuration registers, such as those that control the EMIF or other peripherals. Once the host is finished with all necessary initialization, it must set the DSPINT bit in the HPIC register to complete the boot process. This transition causes the boot configuration logic to bring the CPU out of the “stalled” state. The CPU then begins execution from address 0. The DSPINT condition is not latched by the CPU, because it occurs while the CPU is still internally “stalled”. Also, DSPINT brings the CPU out of the “stalled” state only if the host boot process is selected. All memory may be written to and read by the host. This allows for the host to verify what it sends to the DSP if required. After the CPU is out of the “stalled” state , the CPU needs to clear the DSPINT, otherwise, no more DSPINTs can be received. D Emulation boot Emulation boot mode is a variation of host boot. In this mode, it is not necessary for a host to load code or to set DSPINT to release the CPU from the “stalled” state. Instead, the emulator will set DSPINT if it has not been previously set so that the CPU can begin executing code from address 0. Prior to beginning execution, the emulator sets a breakpoint at address 0. This prevents the execution of invalid code by halting the CPU prior to executing the first instruction. Emulation boot is a good tool in the debug phase of development. D EMIF boot (using default ROM timings) Upon the release of internal reset, the 1K-Byte ROM code located in the beginning of CE1 is copied to address 0 by the EDMA using the default ROM timings, while the CPU is internally “stalled”. The data should be stored in the endian format that the system is using. The boot process also lets you choose the width of the ROM. In this case, the EMIF automatically assembles consecutive 8-bit bytes or 16-bit half-words to form the 32-bit instruction words to be copied. The transfer is automatically done by the EDMA as a single-frame block transfer from the ROM to address 0. After completion of the block transfer, the CPU is released from the “stalled” state and start running from address 0. 96 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 TMS320C6713, TMS320C6713B FLOATING-POINT DIGITAL SIGNAL PROCESSORS SPRS186I − DECEMBER 2001 − REVISED MAY 2004 absolute maximum ratings over operating case temperature range (unless otherwise noted)† Supply voltage range, CVDD (see Note 2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3 V to 1.8 V Supply voltage range, DVDD (see Note 2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3 V to 4 V Input voltage range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3 V to DVDD + 0.5 V Output voltage range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −0.3 V to DVDD + 0.5 V Operating case temperature ranges, TC: (default) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0_C to 90_C (A version) [13GDPA-200 and 13PYPA-167] . . . −40_C to105_C Storage temperature range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . −65_C to 150_C † Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.

As a good board design practice, such delays must always be taken into account. Timing values may be adjusted by increasing/decreasing such delays. TI recommends utilizing the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to attain accurate timing analysis for a given system, see the Using IBIS Models for Timing Analysis application report (literature number SPRA839). If needed, external logic hardware such as buffers may be used to compensate any timing differences. For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin, but also tends to improve the input hold time margins (see Table 47 and Figure 28). Figure 28 represents a general transfer between the DSP and an external device. The figure also represents board route delays and how they are perceived by the DSP and the external device.
