Introduction
This section describes the main features of the TMS320VC5416, lists the pin assignments, and describes
the function of each pin. This data manual also provides a detailed description section, electrical
specifications, parameter measurement information, and mechanical data about the available packaging.
NOTE
This data manual is designed to be used in conjunction with the TMS320C54x™ DSP
Functional Overview (literature number SPRU307).
2.1
Description
The TMS320VC5416 fixed-point, digital signal processor (DSP) (hereafter referred to as the device unless
otherwise specified) is based on an advanced modified Harvard architecture that has one program
memory bus and three data memory buses. This processor provides an arithmetic logic unit (ALU) with a
high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip
peripherals. The basis of the operational flexibility and speed of this DSP is a highly specialized instruction
set.
Separate program and data spaces allow simultaneous access to program instructions and data, providing
a high degree of parallelism. Two read operations and one write operation can be performed in a single
cycle. Instructions with parallel store and application-specific instructions can fully utilize this architecture.
In addition, data can be transferred between data and program spaces. Such parallelism supports a
powerful set of arithmetic, logic, and bit-manipulation operations that can all be performed in a single
machine cycle. The device also includes the control mechanisms to manage interrupts, repeated
operations, and function calls.
2.2
Pin Assignments
Figure 2-1 illustrates the ball locations for the 144-pin ball grid array (BGA) package and is used in
conjunction with Table 2-1 to locate signal names and ball grid numbers. Figure 2-2 provides the pin
assignments for the 144-pin low-profile quad flatpack (LQFP) package.

I/O/Z (2) (3) Parallel data bus D15 (MSB) through D0 (LSB). D15-D0 is multiplexed to transfer data between the core CPU
and external data/program memory or I/O devices or HPI in HPI16 mode (when HPI16 pin is high). D15-D0 is
placed in the high-impedance state when not outputting data or when RS or HOLD is asserted. D15-D0 also
goes into the high-impedance state when OFF is low. These pins also have Schmitt trigger inputs.The data bus
has a bus holder feature that eliminates passive components and the power dissipation associated with them.
The bus holder keeps the data bus at the previous logic level when the bus goes into the high-impedance state.
The bus holders on the data bus can be enabled/disabled under software control.
DESCRIPTION
DATA SIGNALS
Parallel address bus A22 [most significant bit (MSB)] through A0 [least significant bit (LSB)]. The sixteen LSB
lines, A0 to A15, are multiplexed to address external memory (program, data) or I/O. The seven MSB lines, A16
to A22, address external program space memory. A22-A0 is placed in the high-impedance state in the hold
mode. A22-A0 also goes into the high-impedance state when OFF is low.A17-A0 are inputs in HPI16 mode.
These pins can be used to address internal memory via the host-port interface (HPI) when the HPI16 pin is high.
These pins also have Schmitt trigger inputs.The address bus has a bus holder feature that eliminates passive
components and the power dissipation associated with them. The bus holder keeps the address bus at the
previous logic level when the bus goes into a high-impedance state.

MP/MC
Interrupt acknowledge signal. IACK indicates receipt of an interrupt and that the program counter is fetching the
interrupt vector location designated by A15-A0. IACK also goes into the high-impedance state when OFF is low.
I
External user interrupt inputs. INT0-INT3 are maskable and are prioritized by the interrupt mask register (IMR)
and the interrupt mode bit. INT0 -INT3 can be polled and reset by way of the interrupt flag register (IFR).
I
Nonmaskable interrupt. NMI is an external interrupt that cannot be masked by way of the INTM or the IMR.
When NMI is activated, the processor traps to the appropriate vector location.
I
Reset. RS causes the digital signal processor (DSP) to terminate execution and forces the program counter to
0FF80h. When RS is brought to a high level, execution begins at location 0FF80h of program memory. RS
affects various registers and status bits.
I
Microprocessor/microcomputer mode select. If active low at reset, microcomputer mode is selected, and the
internal program ROM is mapped into the upper 16K words of program memory space. If the pin is driven high
during reset, microprocessor mode is selected, and the on-chip ROM is removed from program space. This pin
is only sampled at reset, and the MP/MC bit of the processor mode status (PMST) register can override the
mode that is selected at reset.
I
Branch control. A branch can be conditionally executed when BIO is active. If low, the processor executes the
conditional instruction. The BIO condition is sampled during the decode phase of the pipeline for the XC
instruction, and all other instructions sample BIO during the read phase of the pipeline.
MULTIPROCESSING SIGNALS
BIO
(2)
O/Z
External flag output (latched software-programmable signal). XF is set high by the SSBX XF instruction, set low
by RSBX XF instruction or by loading ST1. XF is used for signaling other processors in multiprocessor
configurations or used as a general-purpose output pin. XF goes into the high-impedance state when OFF is
low, and is set high at reset.
DS
PS
IS
O/Z
Data, program, and I/O space select signals. DS, PS, and IS are always high unless driven low for
communicating to a particular external space. Active period corresponds to valid address information. DS, PS,
and IS are placed into the high-impedance state in the hold mode; these signals also go into the high-impedance
state when OFF is low.
MSTRB
O/Z
Memory strobe signal. MSTRB is always high unless low-level asserted to indicate an external bus access to
data or program memory. MSTRB is placed in the high-impedance state in the hold mode; it also goes into the
high-impedance state when OFF is low.
XF
MEMORY CONTROL SIGNALS

I = Input, O = Output, Z = High-impedance, S = Supply
These pins have Schmitt trigger inputs.
This pin has an internal bus holder controlled by way of the BSCR register.

NAME
I/O (1)
READY
I
DESCRIPTION
Data ready. READY indicates that an external device is prepared for a bus transaction to be completed. If the
device is not ready (READY is low), the processor waits one cycle and checks READY again. Note that the
processor performs ready detection if at least two software wait states are programmed. The READY signal is
not sampled until the completion of the software wait states.
R/W
O/Z
Read/write signal. R/W indicates transfer direction during communication to an external device. R/W is normally
in the read mode (high), unless it is asserted low when the DSP performs a write operation. R/W is placed in the
high-impedance state in the hold mode; and it also goes into the high-impedance state when OFF is low.
IOSTRB
O/Z
I/O strobe signal. IOSTRB is always high unless low-level asserted to indicate an external bus access to an I/O
device. IOSTRB is placed in the high-impedance state in the hold mode; it also goes into the high-impedance
state when OFF is low.
I
Hold input. HOLD is asserted to request control of the address, data, and control lines. When acknowledged by
the device, these lines go into the high-impedance state.
HOLD
O/Z
Hold acknowledge. HOLDA indicates to the external circuitry that the processor is in a hold state and that the
address, data, and control lines are in the high-impedance state, allowing them to be available to the external
circuitry. HOLDA also goes into the high-impedance state when OFF is low. Figure 2-2 This pin is driven high
during reset.
MSC
O/Z
Microstate complete. MSC indicates completion of all software wait states. When two or more software wait
states are enabled, the MSC pin goes active at the beginning of the first software wait state and goes inactive
high at the beginning of the last software wait state. If connected to the READY input, MSC forces one external
wait state after the last internal wait state is completed. MSC also goes into the high-impedance state when OFF
is low.
IAQ
O/Z
Instruction acquisition signal. IAQ is asserted (active low) when there is an instruction address on the address
bus and goes into the high-impedance state when OFF is low.
HOLDA
TIMER SIGNALS
CLKOUT
O/Z
Clock output signal. CLKOUT can represent the machine-cycle rate of the CPU divided by 1, 2, 3, or 4 as
configured in the bank-switching control register (BSCR). Following reset, CLKOUT represents the machine-cycle rate divided by 4.
CLKMD1 (2)
CLKMD2 (2)
CLKMD3 (2)
I
Clock mode select signals. CLKMD1-CLKMD3 allow the selection and configuration of different clock modes
such as crystal, external clock, and PLL mode. The external CLKMD1-CLKMD3 pins are sampled to determine
the desired clock generation mode while RS is low. Following reset, the clock generation mode can be
reconfigured by writing to the internal clock mode register in software.
X2/CLKIN (2)
I
Clock/oscillator input. If the internal oscillator is not being used, X2/CLKIN functions as the clock input. (This is
revision-dependent, see Section Section 3.10 for additional information.)
X1
O
Output pin from the internal oscillator for the crystal. If the internal oscillator is not used, X1 should be left
unconnected. X1 does not go into the high-impedance state when OFF is low. (This is revision-dependent, see
Section Section 3.10 for additional information.)
O/Z
Timer output. TOUT signals a pulse when the on-chip timer counts down past zero. The pulse is one CLKOUT
cycle wide. TOUT also goes into the high-impedance state when OFF is low.
TOUT

BCLKX0 (2)
BCLKX1 (2)
BCLKX2 (2)
I/O/Z
Transmit clock. BCLKX serves as the serial shift clock for the McBSP transmitter. BCLKX can be configured as
an input or an output, and is configured as an input following reset. BCLKX enters the high-impedance state
when OFF goes low.
BDX0, BDX1,
BDX2
O/Z
Serial data transmit output. BDX is placed in the high-impedance state when not transmitting, when RS is
asserted, or when OFF is low.
BFSX0,
BFSX1,
BFSX2
I/O/Z
Frame synchronization pulse for transmit input/output. The BFSX pulse initiates the data transmit process over
BDX. BFSX can be configured as an input or an output, and is configured as an input following reset. BFSX
goes into the high-impedance state when OFF is low.

NAME
I/O (1)
DESCRIPTION
HOST-PORT INTERFACE SIGNALS
I/O/Z
Parallel bidirectional data bus. The HPI data bus is used by a host device bus to exchange information with the
HPI registers. These pins can also be used as general-purpose I/O pins. HD0-HD7 is placed in the
high-impedance state when not outputting data or when OFF is low. The HPI data bus includes bus holders to
reduce the static power dissipation caused by floating, unused pins. When the HPI data bus is not being driven
by the device, the bus holders keep the pins at the previous logic level. The HPI data bus holders are disabled
at reset and can be enabled/disabled via the HBH bit of the BSCR. These pins also have Schmitt trigger inputs.
HCNTL0 (4)
HCNTL1 (4)
I
Control inputs. HCNTL0 and HCNTL1 select a host access to one of the three HPI registers. The control inputs
have internal pullups that are only enabled when HPIENA = 0. These pins are not used when HPI16 = 1.
HBIL (4)
I
Byte identification. HBIL identifies the first or second byte of transfer. The HPIL input has an internal pullup
resistor that is only enabled when HPIENA = 0. This pin is not used when HPI16 = 1.
I
Chip select. HCS is the select input for the HPI and must be driven low during accesses. The chip select input
has an internal pullup resistor that is only enabled when HPIENA = 0.
I
Data strobe. HDS1 and HDS2 are driven by the host read and write strobes to control the transfer. The strobe
inputs have internal pullup resistors that are only enabled when HPIENA = 0.
I
Address strobe. Host with multiplexed address and data pins requires HAS to latch the address in the HPIA
register. HAS input has an internal pullup resistor that is only enabled when HPIENA = 0.
I
Read/write. HR/W controls the direction of the HPI transfer. HR/W has an internal pullup resistor that is only
enabled when HPIENA = 0.

HR/W (4)
HRDY
O/Z
Ready output. HRDY goes into the high-impedance state when OFF is low. The ready output informs the host
when the HPI is ready for the next transfer. This pin is driven high during reset.
HINT
O/Z
Interrupt output. This output is used to interrupt the host. When the DSP is in reset, HINT is driven high. HINT
goes into the high-impedance state when OFF is low. This pin is not used when HPI16 = 1.
HPIENA (5)
I
HPI module select. HPIENA must be tied to DVDD to have HPI selected. If HPIENA is left open or connected to
ground, the HPI module is not selected, internal pullup for the HPI input pins are enabled, and the HPI data bus
has holders set. HPIENA is provided with an internal pulldown resistor that is always active. HPIENA is sampled
when RS goes high and is ignored until RS goes low again. This pin should never be changed while reset is
high.
HPI16 (5)
I
HPI16 mode selection. This pin must be tied to DVDD to enable HPI16 mode. The pin has an internal pulldown
resistor which is always active. If HPI16 is left open or driven low, the HPI16 mode is disabled.

TCK (2) (4)
I
IEEE standard 1149.1 test clock. TCK is normally a free-running clock signal with a 50% duty cycle. The
changes on test access port (TAP) of input signals TMS and TDI are clocked into the TAP controller, instruction
register, or selected test data register on the rising edge of TCK. Changes at the TAP output signal (TDO) occur
on the falling edge of TCK.

progress. TDO also goes into the high-impedance state when OFF is low.
I
IEEE standard 1149.1 test mode select. Pin with internal pullup device. This serial control input is clocked into
the TAP controller on the rising edge of TCK.
I
IEEE standard 1149.1 test reset. TRST, when high, gives the IEEE standard 1149.1 scan system control of the
operations of the device. If TRST is not connected or driven low, the device operates in its functional mode, and
the IEEE standard 1149.1 signals are ignored. Pin with internal pulldown device.
I/O/Z
Emulator 0 pin. When TRST is driven low, EMU0 must be high for activation of the OFF condition. When TRST
is driven high, EMU0 is used as an interrupt to or from the emulator system and is defined as input/output by
way of the IEEE standard 1149.1 scan system.
This pin has an internal pullup resistor.
This pin has an internal pulldown resistor.
This pin must be pulled up with a 4.7-kΩ resistor to ensure the device is operable in functional mode or emulation mode.

emulator system and is defined as input/output by way of IEEE standard 1149.1 scan system. When TRST is
driven low, EMU1/OFF is configured as OFF. The EMU1/OFF signal, when active low, puts all output drivers into
the high-impedance state. Note that OFF is used exclusively for testing and emulation purposes (not for
multiprocessing applications). Therefore, for the OFF condition, the following apply:
TRST = low,
EMU0 = high
EMU1/OFF = low

3.1
Memory
The device provides both on-chip ROM and RAM memories to aid in system performance and integration.
3.1.1
Data Memory
The data memory space addresses up to 64K of 16-bit words. The device automatically accesses the
on-chip RAM when addressing within its bounds. When an address is generated outside the RAM bounds,
the device automatically generates an external access.
The advantages of operating from on-chip memory are as follows:
• Higher performance because no wait states are required

3.1.2
Program Memory
Software can configure their memory cells to reside inside or outside of the program address map. When
the cells are mapped into program space, the device automatically accesses them when their addresses
are within bounds. When the program-address generation (PAGEN) logic generates an address outside its
bounds, the device automatically generates an external access. The advantages of operating from on-chip
memory are as follows:
• Higher performance because no wait states are required
• Lower cost than external memory
• Lower power than external memory
The advantage of operating from off-chip memory is the ability to access a larger address space.
3.1.3
Extended Program Memory
The device uses a paged extended memory scheme in program space to allow access of up to 8192K of
program memory. In order to implement this scheme, the device includes several features which are also
present on C548/549/5410:
• Twenty-three address lines, instead of sixteen
• An extra memory-mapped register, the XPC
• Six extra instructions for addressing extended program space
Program memory in the device is organized into 128 pages that are each 64K in length.
The value of the XPC register defines the page selection. This register is memory-mapped into data space
to address 001Eh. At a hardware reset, the XPC is initialized to 0.
3.2
On-Chip ROM With Bootloader
The device features a 16K-word × 16-bit on-chip maskable ROM that can only be mapped into program
memory space.
Customers can arrange to have the ROM of the device programmed with contents unique to any particular
application.
A bootloader is available in the standard on-chip ROM. This bootloader can be used to automatically
transfer user code from an external source to anywhere in the program memory at power up. If MP/MC of
the device is sampled low during a hardware reset, execution begins at location FF80h of the on-chip
ROM. This location contains a branch instruction to the start of the bootloader program.
The standard devices provide different ways to download the code to accommodate various system
requirements:
• Parallel from 8-bit or 16-bit-wide EPROM
• Parallel from I/O space, 8-bit or 16-bit mode
• Serial boot from serial ports, 8-bit or 16-bit mode
• Host-port interface boot
• Warm boot

In the ROM, 128 words are reserved for factory device-testing purposes. Application code to be implemented in on-chip ROM must
reserve these 128 words at addresses FF00h-FF7Fh in program space.
On-Chip RAM
The device contains 64K-word × 16-bit of on-chip dual-access RAM (DARAM) and 64K-word × 16-bit of
on-chip single-access RAM (SARAM).
The DARAM is composed of eight blocks of 8K words each. Each block in the DARAM can support two
reads in one cycle, or a read and a write in one cycle. Four blocks of DARAM are located in the address
range 0080h-7FFFh in data space, and can be mapped into program/data space by setting the OVLY bit
to one. The other four blocks of DARAM are located in the address range 18000h-1FFFFh in program
space. The DARAM located in the address range 18000h-1FFFFh in program space can be mapped into
data space by setting the DROM bit to one.
The SARAM is composed of eight blocks of 8K words each. Each of these eight blocks is a single-access
memory. For example, an instruction word can be fetched from one SARAM block in the same cycle as a
data word is written to another SARAM block. The SARAM is located in the address range
28000h-2FFFFh, and 38000h-3FFFFh in program space.
3.4
On-Chip Memory Security
The device has a maskable option to protect the contents of on-chip memories.
When the RAM/ROM security option is selected, the following restrictions apply:
• Only the on-chip ROM originating instructions can read the contents of the on-chip ROM; on-chip RAM
and external RAM originating instruction can not read data from ROM: instead 0FFFFh is read. Code
can still branch to ROM from on-chip RAM or external program memory.
• The contents of on-chip RAM can be read by all instructions, even by instructions fetched from external
memory. To protect the internal RAM, the user must never branch to external memory.
• The security feature completely disables the scan-based emulation capability of the 54x to prevent the
use of a debugger utility. This only affects emulation and does not prevent the use of the JTAG
boundary scan test capability.
• The device is internally forced into microcomputer mode at reset (MP/MC bit forced to zero),
preventing the ROM from being disabled by the external MP/MC pin. The status of the MP/MC bit in
the PMST register can be changed after reset by the user application.
• HPI writes have no restriction, but HPI reads are restricted to the 4000h - 5FFFh address range.

• Only the on-chip ROM originating instructions can read the contents of the on-chip ROM; on-chip RAM
and external RAM originating instruction cannot read data from ROM: instead 0FFFFh is read. Code
can still branch to ROM from on-chip RAM or external program memory.
• The contents of on-chip RAM can be read by all instructions, even by instructions fetched from external

• The device can be started in either microcomputer mode or microprocessor mode at reset (depends on
the MP/MC pin).
• HPI read and writes have no restriction.

Relocatable Interrupt Vector Table
The reset, interrupt, and trap vectors are addressed in program space. These vectors are soft — meaning
that the processor, when taking the trap, loads the program counter (PC) with the trap address and
executes the code at the vector location. Four words, either two 1-word instructions or one 2-word
instruction, are reserved at each vector location to accommodate a delayed branch instruction which
allows branching to the appropriate interrupt service routine without the overhead.
At device reset, the reset, interrupt, and trap vectors are mapped to address FF80h in program space.
However, these vectors can be remapped to the beginning of any 128-word page in program space after
device reset. This is done by loading the interrupt vector pointer (IPTR) bits in the PMST register with the
appropriate 128-word page boundary address. After loading IPTR, any user interrupt or trap vector is
mapped to the new 128-word page.
NOTE
The hardware reset (RS) vector cannot be remapped because the hardware reset loads
the IPTR with 1s. Therefore, the reset vector is always fetched at location FF80h in
program space.

these bits are all set to 1; the reset vector always resides at address FF80h in program memory space.
The RESET instruction does not affect this field.
IPTR
MP/MC
Microprocessor/microcomputer mode. MP/MC enables/disables the on-chip ROM to be addressable in
program memory space.
• MP/MC = 0: The on-chip ROM is enabled and addressable.
MP/MC • MP/MC = 1: The on-chip ROM is not available.
pin
MP/MC is set to the value corresponding to the logic level on the MP/MC pin when sampled at reset.
This pin is not sampled again until the next reset. The RESET instruction does not affect this bit. This
bit can also be set or cleared by software.
OVLY
0
RAM overlay. OVLY enables on-chip dual-access data RAM blocks to be mapped into program space.
The values for the OVLY bit are:
• OVLY = 0: The on-chip RAM is addressable in data space but not in program space.
• OVLY = 1: The on-chip RAM is mapped into program space and data space. Data page 0
(addresses 0h to 7Fh), however, is not mapped into program space.
4
AVIS
0
Address visibility mode. AVIS enables/disables the internal program address to be visible at the
address pins.
• AVIS = 0: The external address lines do not change with the internal program address. Control
and data lines are not affected and the address bus is driven with the last address on the bus.
• AVIS = 1: This mode allows the internal program address to appear at the pins of the device so
that the internal program address can be traced. Also, it allows the interrupt vector to be decoded
in conjunction with IACK when the interrupt vectors reside on on-chip memory.
3
DROM
0
DROM enables on-chip DARAM4-7 to be mapped into data space. The DROM bit values are:
• DROM = 0: The on-chip DARAM4-7 is not mapped into data space.
• DROM = 1: The on-chip DARAM4-7 is mapped into data space.

On-Chip Peripherals
The device has the following peripherals:
• Software-programmable wait-state generator
• Programmable bank-switching
• A host-port interface (HPI8/16)
• Three multichannel buffered serial ports (McBSPs)
• A hardware timer
• A clock generator with a multiple phase-locked loop (PLL)
• Enhanced external parallel interface (XIO2)
• A DMA controller (DMA)
3.6.1
Software-Programmable Wait-State Generator
The software wait-state generator of the device can extend external bus cycles by up to fourteen machine
cycles. Devices that require more than fourteen wait states can be interfaced using the hardware READY
line. When all external accesses are configured for zero wait states, the internal clocks to the wait-state
generator are automatically disabled. Disabling the wait-state generator clocks reduces the power
consumption.
The software wait-state register (SWWSR) controls the operation of the wait-state generator. The 14 LSBs
of the SWWSR specify the number of wait states (0 to 7) to be inserted for external memory accesses to
five separate address ranges. This allows a different number of wait states for each of the five address
ranges. Additionally, the software wait-state multiplier (SWSM) bit of the software wait-state control
register (SWCR) defines a multiplication factor of 1 or 2 for the number of wait states. At reset, the
wait-state generator is initialized to provide seven wait states on all external memory accesses. The
SWWSR bit fields are shown in Figure 3-5 and described in Table 3-3.

Programmable Bank-Switching
Programmable bank-switching logic allows the device to switch between external memory banks without
requiring external wait states for memories that need additional time to turn off. The bank-switching logic

or data space.
Bank-switching is defined by the bank-switching control register (BSCR), which is memory-mapped

SPRS095O – MARCH 1999 – REVISED JANUARY 2005
The device has an internal register that holds the MSB of the last address used for a read or write
operation in program or data space. In the non-consecutive bank switches (CONSEC = 0), if the MSB of
the address used for the current read does not match that contained in this internal register, the MSTRB
(memory strobe) signal is not asserted for one CLKOUT cycle. During this extra cycle, the address bus
switches to the new address. The contents of the internal register are replaced with the MSB for the read
of the current address. If the MSB of the address used for the current read matches the bits in the
register, a normal read cycle occurs.
In non-consecutive bank switches (CONSEC = 0), if repeated reads are performed from the same memory
bank, no extra cycles are inserted. When a read is performed from a different memory bank, memory
conflicts are avoided by inserting an extra cycle. For more information, see Section 3.11 of this document.
The bank-switching mechanism automatically inserts one extra cycle in the following cases:
• A memory read followed by another memory read from a different memory bank.
• A program-memory read followed by a data-memory read.
• A data-memory read followed by a program-memory read.
• A program-memory read followed by another program-memory read from a different page.
3.6.3
Bus Holders
The device has two bus holder control bits, BH (BSCR[1]) and HBH (BSCR[2]), to control the bus keepers
of the address bus (A[17-0]), data bus (D[15-0]), and the HPI data bus (HD[7-0]). Bus keeper
enabling/disabling is described in Table 3-6.

3.7.1
Enhanced 8-/16-Bit Host-Port Interface (HPI8/16)
The host-port interface, also referred to as the HPI8/16, is an enhanced version of the standard 8-bit HPI
found on earlier TMS320C54x™ DSPs (542, 545, 548, and 549). The HPI can be used to interface to an
8-bit or 16-bit host. When the address and data buses for external I/O is not used (to interface to external
devices in program/data/IO spaces), the HPI can be configured as an HPI16 to interface to a 16-bit host.
This configuration can be accomplished by connecting the HPI16 pin to logic "1”.
When the HPI16 pin is connected to a logic ,,0”, the HPI is configured as an HPI8. The HPI8 is an 8-bit
parallel port for interprocessor communication. The features of the HPI8 include:
Standard features:
• Sequential transfers (with autoincrement) or random-access transfers
• Host interrupt and C54x™ interrupt capability
• Multiple data strobes and control pins for interface flexibility
The HPI8 interface consists of an 8-bit bidirectional data bus and various control signals. Sixteen-bit
transfers are accomplished in two parts with the HBIL input designating high or low byte. The host
communicates with the HPI8 through three dedicated registers — the HPI address register (HPIA), the
HPI data register (HPID), and the HPI control register (HPIC). The HPIA and HPID registers are only
accessible by the host, and the HPIC register is accessible by both the host and the device.
Enhanced features:
• Access to entire on-chip RAM through DMA bus
• Capability to continue transferring during emulation stop
The HPI16 is an enhanced 16-bit version of the TMS320C54x™ DSP 8-bit host-port interface (HPI8). The
HPI16 is designed to allow a 16-bit host to access the DSP on-chip memory, with the host acting as the
master of the interface. Some of the features of the HPI16 include:
• 16-bit bidirectional data bus
• Multiple data strobes and control signals to allow glueless interfacing to a variety of hosts
• Only nonmultiplexed address/data modes are supported
• 18-bit address bus used in nonmultiplexed mode to allow access to all internal memory (including
internal extended address pages)
• HRDY signal to hold off host accesses due to DMA latency
• The HPI16 acts as a slave to a 16-bit host processor and allows access to the on-chip memory of the
DSP.
NOTE
Only the nonmultiplexed mode is supported when the HPI is configured as a HPI16.
The HPI functions as a slave and enables the host processor to access the on-chip memory. A major
enhancement to the HPI over previous versions is that it allows host access to the entire on-chip memory
range of the DSP. The host and the DSP both have access to the on-chip RAM at all times and host
accesses are always synchronized to the DSP clock. If the host and the DSP contend for access to the
same location, the host has priority, and the DSP waits for one cycle. Note that since host accesses are
always synchronized to the device clock, an active input clock (CLKIN) is required for HPI accesses during
IDLE states, and host accesses are not allowed while the device reset pin is asserted.

3.7.2
HPI Nonmultiplexed Mode
In nonmultiplexed mode, a host with separate address/data buses can access the HPI16 data register
(HPID) via the HD 16-bit bidirectional data bus, and the address register (HPIA) via the 18-bit HA address
bus. The host initiates the access with the strobe signals (HDS1, HDS2, HCS) and controls the direction of
the access with the HR/W signal. The HPI16 can stall host accesses via the HRDY signal. Note that the
HPIC register is not available in nonmultiplexed mode since there are no HCNTL signals available. All
host accesses initiate a DMA read or write access. Figure 3-8 shows a block diagram of the HPI16 in
nonmultiplexed mode. Figure 3-9 shows the HPI memory map.

Multichannel Buffered Serial Ports (McBSPs)
The device provides three high-speed, full-duplex, multichannel buffered serial ports that allow direct
interface to other C54x/LC54x devices, codecs, and other devices in a system. The McBSPs are based on
the standard serial-port interface found on other 54x devices. Like their predecessors, the McBSPs
provide:
• Full-duplex communication
• Double-buffer data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
In addition, the McBSPs have the following capabilities:
• Direct interface to:
– T1/E1 framers
– MVIP switching compatible and ST-BUS compliant devices
– IOM-2 compliant devices
– AC97-compliant devices
– IIS-compliant devices
– Serial peripheral interface
• Multichannel transmit and receive of up to 128 channels
• A wide selection of data sizes, including 8, 12, 16, 20, 24, or 32 bits
• µ-law and A-law companding
• Programmable polarity for both frame synchronization and data clocks
• Programmable internal clock and frame generation
The McBSP consists of a data path and control path. The six pins, BDX, BDR, BFSX, BFSR, BCLKX, and
BCLKR, connect the control and data paths to external devices. The implemented pins can be
programmed as general-purpose I/O pins if they are not used for serial communication.
The data is communicated to devices interfacing to the McBSP by way of the data transmit (BDX) pin for
transmit and the data receive (BDR) pin for receive. The CPU or DMA reads the received data from the
data receive register (DRR) and writes the data to be transmitted to the data transmit register (DXR). Data
written to the DXR is shifted out to BDX by way of the transmit shift register (XSR). Similarly, receive data
on the BDR pin is shifted into the receive shift register (RSR) and copied into the receive buffer register
(RBR). RBR is then copied to DRR, which can be read by the CPU or DMA. This allows internal data
movement and external data communications simultaneously.
Control information in the form of clocking and frame synchronization is communicated by way of BCLKX,
BCLKR, BFSX, and BFSR. The device communicates to the McBSP by way of 16-bit-wide control
registers accessible via the internal peripheral bus.
The control block consists of internal clock generation, frame synchronization signal generation, and their
control, and multichannel selection. This control block sends notification of important events to the CPU
and DMA by way of two interrupt signals, XINT and RINT, and two event signals, XEVT and REVT.
The on-chip companding hardware allows compression and expansion of data in either µ-law or A-law
format. When companding is used, transmitted data is encoded according to the specified companding
law and received data is decoded to 2s complement format.
The sample rate generator provides the McBSP with several means of selecting clocking and framing for
both the receiver and transmitter. Both the receiver and transmitter can select clocking and framing
independently.

TMS320VC5416
Fixed-Point Digital Signal Processor

SPRS095O – MARCH 1999 – REVISED JANUARY 2005
The McBSP allows the multiple channels to be independently selected for the transmitter and receiver.
When multiple channels are selected, each frame represents a time-division multiplexed (TDM) data
stream. In using time-division multiplexed data streams, the CPU may only need to process a few of them.
Thus, to save memory and bus bandwidth, multichannel selection allows independent enabling of
particular channels for transmission and reception. All 128 channels in a bit stream consisting of a
maximum of 128 channels can be enabled.

Figure 3-11. Multichannel Control Register (MCR2)
The McBSP has two working modes:
• In the first mode, when (R/X)MCME = 0, it is comparable with the McBSPs used in the 5410 where the
normal 32-channel selection is enabled (default).
• In the second mode, when (R/X)MCME = 1, it has 128-channel selection capability. Multichannel
control register Bit 9, (R/X)MCME, is used as the 128-channel selection enable bit. Once (R/X)MCME
= 1, twelve new registers ((R/X)CERC - (R/X)CERH) are used to enable the 128-channel selection.
The clock stop mode (CLKSTP) in the McBSP provides compatibility with the serial port interface protocol.
Clock stop mode works with only single-phase frames and one word per frame. The word sizes supported
by the McBSP are programmable for 8-, 12-, 16-, 20-, 24-, or 32-bit operation. When the McBSP is
configured to operate in SPI mode, both the transmitter and the receiver operate together as a master or
as a slave.
Although the BCLKS pin is not available on the device PGE and GGU packages, the device is capable of
synchronization to external clock sources. BCLKX or BCLKR can be used by the sample rate generator
for external synchronization. The sample rate clock mode extended (SCLKME) bit field is located in the
PCR to accommodate this option.

The selection of sample rate input clock is made by the combination of the CLKSM (bit 13 in SRGR2) bit

When the SCLKME bit is cleared to 0, the CLKSM bit is used, as before, to select either the CPU clock or
the CLKS pin (not bonded out on the device package) as the sample rate input clock. Setting the
SCLKME bit to 1 enables the CLKSM bit to select between the BCLKR pin or BCLKX pin for the sample
rate input clock.
When either the BCLKR or CLKX is configured this way, the output buffer for the selected pin is
automatically disabled. For example, with SCLKME = 1 and CLKSM = 0, the BCLKR pin is configured as
the input of the sample rate generator. Both the transmitter and receiver circuits can be synchronized to
the sample rate generator output by setting the CLKXM and CLKRM bits of the pin configuration register
(PCR) to 1. Note that the sample rate generator output will only be driven on the BCLKX pin since the
BCLKR output buffer is automatically disabled.
The McBSP is fully static and operates at arbitrary low clock frequencies. For maximum operating
frequency, see Section 5.5.10.
3.9
Hardware Timer
The device features a 16-bit timing circuit with a 4-bit prescaler. The timer counter is decremented by one
every CLKOUT cycle. Each time the counter decrements to 0, a timer interrupt is generated. The timer
can be stopped, restarted, reset, or disabled by specific status bits.
3.10
Clock Generator
The clock generator provides clocks to the device, and consists of a phase-locked loop (PLL) circuit. The
clock generator requires a reference clock input, which can be provided from an external clock source.
The reference clock input is then divided by two (DIV mode) to generate clocks for the device, or the PLL
circuit can be used (PLL mode) to generate the device clock by multiplying the reference clock frequency
by a scale factor, allowing use of a clock source with a lower frequency than that of the CPU. The PLL is
an adaptive circuit that, once synchronized, locks onto and tracks an input clock signal.
When the PLL is initially started, it enters a transitional mode during which the PLL acquires lock with the
input signal. Once the PLL is locked, it continues to track and maintain synchronization with the input
signal. Then, other internal clock circuitry allows the synthesis of new clock frequencies for use as master
clock for the device.

SPRS095O – MARCH 1999 – REVISED JANUARY 2005
This clock generator allows system designers to select the clock source. The sources that drive the clock
generator are:
• A crystal resonator circuit. The crystal resonator circuit is connected across the X1 and X2/CLKIN pins
of the device to enable the internal oscillator.
• An external clock. The external clock source is directly connected to the X2/CLKIN pin, and X1 is left
unconnected.
NOTE
The crystal oscillator function is not supported by all die revisions of the device. See the
TMS320VC5416 Digital Signal Processor Silicon Errata (literature number SPRZ172) to
verify which die revisions support this functionality.
The software-programmable PLL features a high level of flexibility, and includes a clock scaler that
provides various clock multiplier ratios, capability to directly enable and disable the PLL, and a PLL lock
timer that can be used to delay switching to PLL clocking mode of the device until lock is achieved.
Devices that have a built-in software-programmable PLL can be configured in one of two clock modes:
• PLL mode. The input clock (X2/CLKIN) is multiplied by 1 of 31 possible ratios.
• DIV (divider) mode. The input clock is divided by 2 or 4. Note that when DIV mode is used, the PLL
can be completely disabled in order to minimize power dissipation.
The software-programmable PLL is controlled using the 16-bit memory-mapped (address 0058h) clock
mode register (CLKMD). The CLKMD register is used to define the clock configuration of the PLL clock
module. Note that upon reset, the CLKMD register is initialized with a predetermined value dependent only
upon the state of the CLKMD1 - CLKMD3 pins. For more programming information, see the TMS320C54x
DSP Reference Set, Volume 1: CPU and Peripherals (literature number SPRU131). The CLKMD pin
configured clock options are shown in Table 3-8.

Enhanced External Parallel Interface (XIO2)
The device external interface has been redesigned to include several improvements, including:
simplification of the bus sequence, more immunity to bus contention when transitioning between read and
write operations, the ability for external memory access to the DMA controller, and optimization of the
power-down modes.
The bus sequence on the device still maintains all of the same interface signals as on previous 54x
devices, but the signal sequence has been simplified. Most external accesses now require 3 cycles
composed of a leading cycle, an active (read or write) cycle, and a trailing cycle. The leading and trailing
cycles provide additional immunity against bus contention when switching between read operations and
write operations. To maintain high-speed read access, a consecutive read mode that performs
single-cycle reads as on previous 54x devices is available.
Figure 3-13 shows the bus sequence for three cases: all I/O reads, memory reads in nonconsecutive
mode, or single memory reads in consecutive mode. The accesses shown in Figure 3-13 always require 3
CLKOUT cycles to complete.

The enhanced interface also provides the ability for DMA transfers to extend to external memory. For
more information on DMA capability, see the DMA sections that follow.
The enhanced interface improves the low-power performance already present on the TMS320C5000™
DSP platform by switching off the internal clocks to the interface when it is not being used. This
power-saving feature is automatic, requires no software setup, and causes no latency in the operation of
the interface.
Additional features integrated in the enhanced interface are the ability to automatically insert
bank-switching cycles when crossing 32K memory boundaries (see Section 3.6.2), the ability to program
up to 14 wait states through software (see Section 3.6.1), and the ability to divide down CLKOUT by a
factor of 1, 2, 3, or 4. Dividing down CLKOUT provides an alternative to wait states when interfacing to
slower external memory or peripheral devices. While inserting wait states extends the bus sequence
during read or write accesses, it does not slow down the bus signal sequences at the beginning and the
end of the access. Dividing down CLKOUT provides a method of slowing the entire bus sequence when
necessary. The CLKOUT divide-down factor is controlled through the DIVFCT field in the bank-switching
control register (BSCR) (see Table 3-5).

DMA Controller
The device direct memory access (DMA) controller transfers data between points in the memory map
without intervention by the CPU. The DMA allows movements of data to and from internal program/data
memory, internal peripherals (such as the McBSPs), or external memory devices to occur in the
background of CPU operation. The DMA has six independent programmable channels, allowing six
different contexts for DMA operation.
3.12.1
Features
The DMA has the following features:
• The DMA operates independently of the CPU.
• The DMA has six channels. The DMA can keep track of the contexts of six independent block
transfers.
• The DMA has higher priority than the CPU for both internal and external accesses.
• Each channel has independently programmable priorities.
• Each channel's source and destination address registers can have configurable indexes through
memory on each read and write transfer, respectively. The address may remain constant, be
post-incremented, be post-decremented, or be adjusted by a programmable value.
• Each read or write internal transfer may be initialized by selected events.
• On completion of a half- or entire-block transfer, each DMA channel may send an interrupt to the CPU.
• The DMA can perform double-word internal transfers (a 32-bit transfer of two 16-bit words).
3.12.2
DMA External Access
The DMA supports external accesses to data, I/O, and extended program memory. These overlay pages
are only visible to the DMA controller. A maximum of two DMA channels can be used for external memory
accesses. The DMA external accesses require a minimum of 8 cycles for external writes and a minimum
of 11 cycles for external reads assuming the XIO02 is in consecutive mode (CONSEC = 1), wait state is
set to two, and CLKOUT is not divided (DIVFCT = 00).
The control of the bus is arbitrated between the CPU and the DMA. While the DMA or CPU is in control of
the external bus, the other will be held-off via wait states until the current transfer is complete. The DMA
takes precedence over XIO requests.
• Only two channels are available for external accesses. (One for external reads and one for external
writes.)
• Single-word (16-bit) transfers are supported for external accesses.
• The DMA does not support transfers from the peripherals to external memory.
• The DMA does not support transfers from external memory to the peripherals.
• The DMA does not support external-to-external accesses.
• The DMA does not support synchronized external accesses.

DMA Priority Level
Each DMA channel can be independently assigned high- or low-priority relative to each other. Multiple
DMA channels that are assigned to the same priority level are handled in a round-robin manner.
3.12.5
DMA Source/Destination Address Modification
The DMA provides flexible address-indexing modes for easy implementation of data management
schemes such as autobuffering and circular buffers. Source and destination addresses can be indexed
separately and can be post-incremented, post-decremented, or post-incremented with a specified index
offset.

3.12.6
DMA in Autoinitialization Mode
The DMA can automatically reinitialize itself after completion of a block transfer. Some of the DMA
registers can be preloaded for the next block transfer through the DMA reload registers (DMGSA,
DMGDA, DMGCR, and DMGFR). Autoinitialization allows:
• Continuous operation: Normally, the CPU would have to reinitialize the DMA immediately after the
completion of the current block transfers, but with the reload registers, it can reinitialize these values
for the next block transfer any time after the current block transfer begins.
• Repetitive operation:The CPU does not preload the reload register with new values for each block
transfer but only loads them on the first block transfer.
The DMA has been enhanced to expand the DMA reload register sets. Each DMA channel now has its
own DMA reload register set. For example, the DMA reload register set for channel 0 has DMGSA0,
DMGDA0, DMGCR0, and DMGFR0 while DMA channel 1 has DMGSA1, DMGDA1, DMGCR1, and
DMGFR1, etc.
To utilize the additional DMA reload registers, the AUTOIX bit is added to the DMPREC register as shown
in Figure 3-19.

DMA RELOAD REGISTER USAGE IN AUTO INIT MODE
All DMA channels use DMGSA0, DMGDA0, DMGCR0 and DMGFR0
Each DMA channel uses its own set of reload registers
DMA Transfer Counting
The DMA channel element count register (DMCTRx) and the frame count register (DMFRCx) contain bit
fields that represent the number of frames and the number of elements per frame to be transferred.
• Frame count. This 8-bit value defines the total number of frames in the block transfer. The maximum
number of frames per block transfer is 128 (FRAME COUNT= 0FFh). The counter is decremented
upon the last read transfer in a frame transfer. Once the last frame is transferred, the selected 8-bit
counter is reloaded with the DMA global frame reload register (DMGFR) if the AUTOINIT bit is set to 1.
A frame count of 0 (default value) means the block transfer contains a single frame.
• Element count. This 16-bit value defines the number of elements per frame. This counter is
decremented after the read transfer of each element. The maximum number of elements per frame is
65536 (DMCTRn = 0FFFFh). In autoinitialization mode, once the last frame is transferred, the counter
is reloaded with the DMA global count reload register (DMGCR).

3.12.8
DMA Transfer in Doubleword Mode
Doubleword mode allows the DMA to transfer 32-bit words in any index mode. In doubleword mode, two
consecutive 16-bit transfers are initiated and the source and destination addresses are automatically
updated following each transfer. In this mode, each 32-bit word is considered to be one element.
3.12.9
DMA Channel Index Registers
The particular DMA channel index register is selected by way of the SIND and DIND fields in the DMA
transfer mode control register (DMMCRn). Unlike basic address adjustment, in conjunction with the frame
index DMFRI0 and DMFRI1, the DMA allows different adjustment amounts depending on whether or not
the element transfer is the last in the current frame. The normal adjustment value (element index) is
contained in the element index registers DMIDX0 and DMIDX1. The adjustment value (frame index) for
the end of the frame, is determined by the selected DMA frame index register, either DMFRI0 or DMFRI1.
The element index and the frame index affect address adjustment as follows:
• Element index: For all except the last transfer in the frame, the element index determines the amount
to be added to the DMA channel for the source/destination address register (DMSRCx/DMDSTx) as
selected by the SIND/DIND bits.
• Frame index: If the transfer is the last in a frame, frame index is used for address adjustment as
selected by the SIND/DIND bits. This occurs in both single-frame and multiframe transfers.
3.12.10
DMA Interrupts
The ability of the DMA to interrupt the CPU based on the status of the data transfer is configurable and is
determined by the IMOD and DINM bits in the DMA transfer mode control register (DMMCRn). The
available modes are shown in Table 3-11.

The DMA controller can generate a CPU interrupt for each of the six channels. However, due to a limit on
the number of internal CPU interrupt inputs, channels 0, 1, 2, and 3 are multiplexed with other interrupt
sources. DMA channels 0, 1, 2, and 3 share an interrupt line with the receive and transmit portions of the
McBSP. When the device is reset, the interrupts from these three DMA channels are deselected. The
INTSEL bit field in the DMPREC register can be used to select these interrupts, as shown in Table 3-13.

General-Purpose I/O Pins
In addition to the standard BIO and XF pins, the device has pins that can be configured for
general-purpose I/O. These pins are:
• 18 McBSP pins
– BCLKX0/1/2,
– BCLKR0/1/2
– BDR0/1/2
– BFSX0/1/2
– BFSR0/1/2
– BDX0/1/2
• 8 HPI data pins
– HD0-HD7
The general-purpose I/O function of these pins is only available when the primary pin function is not
required.
3.13.1
McBSP Pins as General-Purpose I/O
When the receive or transmit portion of a McBSP is in reset, its pins can be configured as
general-purpose inputs or outputs. For more details on this feature, see Section 3.8.

DMA Subbank Addressed Registers
The direct memory access (DMA) controller has several control registers associated with it. The main
control register (DMPREC) is a standard memory-mapped register. However, the other registers are
accessed using the subbank addressing scheme. This allows a set or subbank of registers to be accessed
through a single memory location. The DMA subbank address (DMSA) register is used as a pointer to
select a particular register within the subbank, while the DMA subbank data (DMSD) register or the DMA
subbank data register with autoincrement (DMSDI) is used to access (read or write) the selected register.
When the DMSDI register is used to access the subbank, the subbank address is automatically
postincremented so that a subsequent access affects the next register within the subbank. This
autoincrement feature is intended for efficient, successive accesses to several control registers. If the
autoincrement feature is not required, the DMSDN register should be used to access the subbank.
Table 3-18 shows the DMA controller subbank addressed registers and their corresponding subaddresses.

Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
TMS320 DSP devices and support tools. Each TMS320 DSP commercial family member has one of three
prefixes: TMX, TMP, or TMS (e.g., TMS320C6412GDK600). Texas Instruments recommends two of three
possible prefix designators for its support tools: TMDX and TMDS. These prefixes represent evolutionary
stages of product development from engineering prototypes (TMX/TMDX) through fully qualified
production devices/tools (TMS/TMDS).
Device development evolutionary flow:
TMX
Experimental device that is not necessarily representative of the final device's electrical
specifications
TMP
Final silicon die that conforms to the device's electrical specifications but has not completed
quality and reliability verification
TMS
Fully qualified production device
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully qualified development-support product
TMX and TMP devices and TMDX development-support tools are shipped with appropriate disclaimers
describing their limitations and intended uses.
"Developmental product is intended for internal evaluation purposes."
TMS devices and TMDS development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies.
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.

5.3.3
Internal Oscillator With External Crystal
The internal oscillator is enabled by selecting the appropriate clock mode at reset (this is device-dependent; see Section Section 3.10) and connecting a crystal or ceramic resonator across X1 and
X2/CLKIN. The CPU clock frequency is one-half, one-fourth, or a multiple of the oscillator frequency. The
multiply ratio is determined by the bit settings in the CLKMD register.
The crystal should be in fundamental-mode operation, and parallel resonant, with an effective series
resistance of 30 Ω maximum and power dissipation of 1 mW. The connection of the required circuit,
consisting of the crystal and two load capacitors, is shown in Figure 5-2. The load capacitors, C1 and C2,
should be chosen such that the equation below is satisfied. CL (recommended value of 10 pF) in the
equation is the load specified for the crystal.

Clock Options
The frequency of the reference clock provided at the CLKIN pin can be divided by a factor of two or four or
multiplied by one of several values to generate the internal machine cycle.
5.4.1
Divide-By-Two and Divide-By-Four Clock Options
The frequency of the reference clock provided at the X2/CLKIN pin can be divided by a factor of two or four to
generate the internal machine cycle. The selection of the clock mode is described in Section Section 3.10.
When an external clock source is used, the frequency injected must conform to specifications listed in Table 5-3.
An external frequency source can be used by applying an input clock to X2/CLKIN with X1 left unconnected.
Table 5-2 shows the configuration options for the CLKMD pins that generate the external divide-by-2 or
divide-by-4 clock option. Table 5-3 and Table 5-4 assume testing over recommended operating conditions and H
= 0.5tc(CO) (see Figure 5-3).

5.4.2
Multiply-By-N Clock Option (PLL Enabled)
The frequency of the reference clock provided at the X2/CLKIN pin can be multiplied by a factor of N to generate
the internal machine cycle. The selection of the clock mode and the value of N is described in Section
Section 3.10. Following reset, the software PLL can be programmed for the desired multiplication factor. Refer to
the TMS320C54x DSP Reference Set, Volume 1: CPU and Peripherals (literature number SPRU131) for detailed
information on programming the PLL.
When an external clock source is used, the external frequency injected must conform to specifications listed in
Table 5-5.
Table 5-5 and Table 5-6 assume testing over recommended operating conditions and H = 0.5tc(CO) (see
Figure 5-4).

These inputs can be driven from an asynchronous source, therefore, there are no specific timing requirements with respect to CLKOUT,
however, if setup and hod timings are met, the input will be recognized on the CLKOUT edge referenced.
The external interrupts (INT0-INT3, NMI) are synchronized to the core CPU by way of a two-flip-flop synchronizer that samples thse
inputs with consecutive falling edges of CLKOUT. The input to the interrupt pins is required to represent a1-0-0 sequence at the timing
that is corresponding to three CLKOUTs sampling sequence.
If the PLL mode is selected, then at power-on sequence, or at wakeup from IDLE3, RS must be held low for at least 50 µs to ensure
synchronization and lock-in of the PLL.
Note that RS may cause a change in clock frequency, therefore changing the value of H.

CLKRP = CLKXP = FSRP = FSXP = 0. If the polaritiy of any of the signals is inverted, then the timing references of that signal are also
inverted.
Note that in some cases, for example when driving another 54x device McBSP, maximum serial port clocking rates may not be
achievable at maximum CPU clock frequency due to transmitted data timings and corresponding receive timing requirements. A
separate detailed timing analysis should be performend for each specific McBSP interface.

DMAS stands for direct memory access controller. The HPI8 shares the internal DMA bus with the DMAC, thus HPI8 access times are
affected by DMAC activity.
The HRDY output is always high when the HCS input is high, regardless of DS timings.
This timing applies when writing a one to the DSPINT bit or HINT bit of the HPIC register. All other writes to the HPIC occur
asynchronously, and do not cause HRDY to be deasserted.
