Instruments.
All trademarks are the property of their respective owners.
This device is a Low-power applications processor based on an ARM926EJ-S™ and a C674x DSP core. It
provides significantly lower power than other members of the TMS320C6000™ platform of DSPs.
This device enables OEMs and ODMs to quickly bring to market devices featuring robust operating
systems support, rich user interfaces, and high processing performance life through the maximum
flexibility of a fully integrated mixed processor solution.
The dual-core architecture of the device provides benefits of both DSP and Reduced Instruction Set
Computer (RISC) technologies, incorporating a high-performance TMS320C674x DSP core and an
ARM926EJ-S core.
The ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and
processes 32-bit, 16-bit, or 8-bit data. The core uses pipelining so that all parts of the processor and
memory system can operate continuously.
The ARM core has a coprocessor 15 (CP15), protection module, and Data and program Memory
Management Units (MMUs) with table look-aside buffers. It has separate 16K-byte instruction and
16K-byte data caches. Both are four-way associative with virtual index virtual tag (VIVT). The ARM core
also has a 8KB RAM (Vector Table) and 64KB ROM.
The device DSP core uses a two-level cache-based architecture. The Level 1 program cache (L1P) is a
32KB direct mapped cache and the Level 1 data cache (L1D) is a 32KB 2-way set-associative cache. The
Level 2 program cache (L2P) consists of a 256KB memory space that is shared between program and
data space. L2 memory can be configured as mapped memory, cache, or combinations of the two.
Although the DSP L2 is accessible by ARM and other hosts in the system, an additional 128KB RAM
shared memory is available for use by other hosts without affecting DSP performance.
The peripheral set includes: a 10/100 Mb/s Ethernet MAC (EMAC) with a Management Data Input/Output
(MDIO) module; one USB2.0 OTG interface; one USB1.1 OHCI interface; two inter-integrated circuit (I2C)
Bus interfaces; one multichannel audio serial port (McASP) with 16 serializers and FIFO buffers; two
multichannel buffered serial ports (McBSP) with FIFO buffers; two SPI interfaces with multiple chip
selects; four 64-bit general-purpose timers each configurable (one configurable as watchdog); a
configurable 16-bit host port interface (HPI) ; up to 9 banks of 16 pins of general-purpose input/output
(GPIO) with programmable interrupt/event generation modes, multiplexed with other peripherals; three
UART interfaces (each with RTS and CTS); two enhanced high-resolution pulse width modulator
(eHRPWM) peripherals; 3 32-bit enhanced capture (eCAP) module peripherals which can be configured
as 3 capture inputs or 3 auxiliary pulse width modulator (APWM) outputs; and 2 external memory
interfaces: an asynchronous and SDRAM external memory interface (EMIFA) for slower memories or
peripherals, and a higher speed DDR2/Mobile DDR controller.
The Ethernet Media Access Controller (EMAC) provides an efficient interface between the device and a
network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps
in either half- or full-duplex mode. Additionally an Management Data Input/Output (MDIO) interface is
available for PHY configuration. The EMAC supports both MII and RMII interfaces.
The SATA controller provides a high-speed interface to mass data storage devices. The SATA controller
supports both SATA I (1.5 Gbps) and SATA II (3.0 Gbps).
The Universal Parallel Port (uPP) provides a high-speed interface to many types of data converters,
FPGAs or other parallel devices. The UPP supports programmable data widths between 8- to 16-bits on
each of two channels. Single-data rate and double-data rate transfers are supported as well as START,
ENABLE and WAIT signals to provide control for a variety of data converters.
A Video Port Interface (VPIF) is included providing a flexible video input/output port.

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

2.4.1
SLVSAQ9 – JANUARY 2011
ARM926EJ-S RISC CPU
The ARM Subsystem integrates the ARM926EJ-S processor. The ARM926EJ-S processor is a member of
ARM9 family of general-purpose microprocessors. This processor is targeted at multi-tasking applications
where full memory management, high performance, low die size, and low power are all important. The
ARM926EJ-S processor supports the 32-bit ARM and 16 bit THUMB instruction sets, enabling the user to
trade off between high performance and high code density. Specifically, the ARM926EJ-S processor
supports the ARMv5TEJ instruction set, which includes features for efficient execution of Java byte codes,
providing Java performance similar to Just in Time (JIT) Java interpreter, but without associated code
overhead.
The ARM926EJ-S processor supports the ARM debug architecture and includes logic to assist in both
hardware and software debug. The ARM926EJ-S processor has a Harvard architecture and provides a
complete high performance subsystem, including:
• ARM926EJ -S integer core
• CP15 system control coprocessor
• Memory Management Unit (MMU)
• Separate instruction and data caches
• Write buffer
• Separate instruction and data (internal RAM) interfaces
• Separate instruction and data AHB bus interfaces
• Embedded Trace Module and Embedded Trace Buffer (ETM/ETB)
For more complete details on the ARM9, refer to the ARM926EJ-S Technical Reference Manual, available
at http://www.arm.com
2.4.2
CP15
The ARM926EJ-S system control coprocessor (CP15) is used to configure and control instruction and
data caches, Memory Management Unit (MMU), and other ARM subsystem functions. The CP15 registers
are programmed using the MRC and MCR ARM instructions, when the ARM in a privileged mode such as
supervisor or system mode.
2.4.3
MMU
A single set of two level page tables stored in main memory is used to control the address translation,
permission checks and memory region attributes for both data and instruction accesses. The MMU uses a
single unified Translation Lookaside Buffer (TLB) to cache the information held in the page tables. The
MMU features are:
• Standard ARM architecture v4 and v5 MMU mapping sizes, domains and access protection scheme.
• Mapping sizes are:
– 1MB (sections)
– 64KB (large pages)
– 4KB (small pages)
– 1KB (tiny pages)
• Access permissions for large pages and small pages can be specified separately for each quarter of
the page (subpage permissions)
• Hardware page table walks
• Invalidate entire TLB, using CP15 register 8
• Invalidate TLB entry, selected by MVA, using CP15 register 8
• Lockdown of TLB entries, using CP15 register 10

Caches and Write Buffer
The size of the Instruction cache is 16KB, Data cache is 16KB. Additionally, the caches have the following
features:
• Virtual index, virtual tag, and addressed using the Modified Virtual Address (MVA)
• Four-way set associative, with a cache line length of eight words per line (32-bytes per line) and with
two dirty bits in the Dcache
• Dcache supports write-through and write-back (or copy back) cache operation, selected by memory
region using the C and B bits in the MMU translation tables
• Critical-word first cache refilling
• Cache lockdown registers enable control over which cache ways are used for allocation on a line fill,
providing a mechanism for both lockdown, and controlling cache corruption
• Dcache stores the Physical Address TAG (PA TAG) corresponding to each Dcache entry in the TAG
RAM for use during the cache line write-backs, in addition to the Virtual Address TAG stored in the
TAG RAM. This means that the MMU is not involved in Dcache write-back operations, removing the
possibility of TLB misses related to the write-back address.
• Cache maintenance operations provide efficient invalidation of, the entire Dcache or Icache, regions of
the Dcache or Icache, and regions of virtual memory.
The write buffer is used for all writes to a noncachable bufferable region, write-through region and write
misses to a write-back region. A separate buffer is incorporated in the Dcache for holding write-back for
cache line evictions or cleaning of dirty cache lines. The main write buffer has 16-word data buffer and a
four-address buffer. The Dcache write-back has eight data word entries and a single address entry.
2.4.5
Advanced High-Performance Bus (AHB)
The ARM Subsystem uses the AHB port of the ARM926EJ-S to connect the ARM to the Config bus and
the external memories. Arbiters are employed to arbitrate access to the separate D-AHB and I-AHB by the
Config Bus and the external memories bus.
2.4.6
Embedded Trace Macrocell (ETM) and Embedded Trace Buffer (ETB)
To support real-time trace, the ARM926EJ-S processor provides an interface to enable connection of an
Embedded Trace Macrocell (ETM). The ARM926ES-J Subsystem in the device also includes the
Embedded Trace Buffer (ETB). The ETM consists of two parts:
• Trace Port provides real-time trace capability for the ARM9.
• Triggering facilities provide trigger resources, which include address and data comparators, counter,
and sequencers.
The device trace port is not pinned out and is instead only connected to the Embedded Trace Buffer. The
ETB has a 4KB buffer memory. ETB enabled debug tools are required to read/interpret the captured trace
data.
2.4.7
ARM Memory Mapping
By default the ARM has access to most on and off chip memory areas, including the DSP Internal
memories, EMIFA, DDR2, and the additional 128K byte on chip shared SRAM. Likewise almost all of the
on chip peripherals are accessible to the ARM by default.
See Table 2-4 for a detailed top level device memory map that includes the ARM memory space.

C674x DSP CPU Description
The C674x Central Processing Unit (CPU) consists of eight functional units, two register files, and two
data paths as shown in Figure 2-2. The two general-purpose register files (A and B) each contain
32 32-bit registers for a total of 64 registers. The general-purpose registers can be used for data or can be
data address pointers. The data types supported include packed 8-bit data, packed 16-bit data, 32-bit
data, 40-bit data, and 64-bit data. Values larger than 32 bits, such as 40-bit-long or 64-bit-long values are
stored in register pairs, with the 32 LSBs of data placed in an even register and the remaining 8 or
32 MSBs in the next upper register (which is always an odd-numbered register).
The eight functional units (.M1, .L1, .D1, .S1, .M2, .L2, .D2, and .S2) are each capable of executing one
instruction every clock cycle. The .M functional units perform all multiply operations. The .S and .L units
perform a general set of arithmetic, logical, and branch functions. The .D units primarily load data from
memory to the register file and store results from the register file into memory.
The C674x CPU combines the performance of the C64x+ core with the floating-point capabilities of the
C67x+ core.
Each C674x .M unit can perform one of the following each clock cycle: one 32 x 32 bit multiply, one 16 x
32 bit multiply, two 16 x 16 bit multiplies, two 16 x 32 bit multiplies, two 16 x 16 bit multiplies with
add/subtract capabilities, four 8 x 8 bit multiplies, four 8 x 8 bit multiplies with add operations, and four
16 x 16 multiplies with add/subtract capabilities (including a complex multiply). There is also support for
Galois field multiplication for 8-bit and 32-bit data. Many communications algorithms such as FFTs and
modems require complex multiplication. The complex multiply (CMPY) instruction takes for 16-bit inputs
and produces a 32-bit real and a 32-bit imaginary output. There are also complex multiplies with rounding
capability that produces one 32-bit packed output that contain 16-bit real and 16-bit imaginary values. The
32 x 32 bit multiply instructions provide the extended precision necessary for high-precision algorithms on
a variety of signed and unsigned 32-bit data types.
The .L or (Arithmetic Logic Unit) now incorporates the ability to do parallel add/subtract operations on a
pair of common inputs. Versions of this instruction exist to work on 32-bit data or on pairs of 16-bit data
performing dual 16-bit add and subtracts in parallel. There are also saturated forms of these instructions.
The C674x core enhances the .S unit in several ways. On the previous cores, dual 16-bit MIN2 and MAX2
comparisons were only available on the .L units. On the C674x core they are also available on the .S unit
which increases the performance of algorithms that do searching and sorting. Finally, to increase data
packing and unpacking throughput, the .S unit allows sustained high performance for the quad 8-bit/16-bit
and dual 16-bit instructions. Unpack instructions prepare 8-bit data for parallel 16-bit operations. Pack
instructions return parallel results to output precision including saturation support.
Other new features include:
• SPLOOP - A small instruction buffer in the CPU that aids in creation of software pipelining loops where
multiple iterations of a loop are executed in parallel. The SPLOOP buffer reduces the code size
associated with software pipelining. Furthermore, loops in the SPLOOP buffer are fully interruptible.
• Compact Instructions - The native instruction size for the C6000 devices is 32 bits. Many common
instructions such as MPY, AND, OR, ADD, and SUB can be expressed as 16 bits if the C674x
compiler can restrict the code to use certain registers in the register file. This compression is
performed by the code generation tools.
• Instruction Set Enhancement - As noted above, there are new instructions such as 32-bit
multiplications, complex multiplications, packing, sorting, bit manipulation, and 32-bit Galois field
multiplication.
• Exceptions Handling - Intended to aid the programmer in isolating bugs. The C674x CPU is able to
detect and respond to exceptions, both from internally detected sources (such as illegal op-codes) and
from system events (such as a watchdog time expiration).
• Privilege - Defines user and supervisor modes of operation, allowing the operating system to give a
basic level of protection to sensitive resources. Local memory is divided into multiple pages, each with
read, write, and execute permissions.

Pin Assignments
Extensive use of pin multiplexing is used to accommodate the largest number of peripheral functions in
the smallest possible package. Pin multiplexing is controlled using a combination of hardware
configuration at device reset and software programmable register settings.
2.7.1
Pin Map (Bottom View)
The following graphics show the bottom view of the GWT package pin assignments in four quadrants (A,
B, C, and D). The pin assignments for both packages are identical.

Pin Multiplexing Control
Device level pin multiplexing is controlled by registers PINMUX0 - PINMUX19 in the SYSCFG module.
For the device family, pin multiplexing can be controlled on a pin-by-pin basis. Each pin that is multiplexed
with several different functions has a corresponding 4-bit field in one of the PINMUX registers.
Pin multiplexing selects which of several peripheral pin functions controls the pin's IO buffer output data
and output enable values only. The default pin multiplexing control for almost every pin is to select 'none'
of the peripheral functions in which case the pin's IO buffer is held tri-stated.
Note that the input from each pin is always routed to all of the peripherals that share the pin; the PINMUX
registers have no effect on input from a pin.

This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can
be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of
power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power
supply DVDD3318_C.
Open drain mode for RESETOUT function.
GP8[0] is initially configured as a reserved function after reset and will not be in a predictable state. This signal will only be stable after
the GPIO configuration for this pin has been completed. Users should carefully consider the system implications of this pin being in an
unknown state after reset.

DESCRIPTION
EMIFA data bus
I = Input, O = Output, I/O = Bidirectional, Z = High impedance, PWR = Supply voltage, GND = Ground, A = Analog signal.
Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the signal name
highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured
function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different
types (ie., input versus output), the table reflects the pin function direction for that particular peripheral.
IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using
the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the

I = Input, O = Output, I/O = Bidirectional, Z = High impedance, PWR = Supply voltage, GND = Ground, A = Analog signal.
Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the signal name
highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured
function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different
types (ie., input versus output), the table reflects the pin function direction for that particular peripheral.
IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using
the PUPDENA and PUPDSEL registers in the System Module.

IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using
the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the
device is out of reset. During reset, all of the pins associated with these registers are pulled down. If the application requires a pull-up,
an external pull-up can be used. For electrical specifications on the pull-up and and internal pull-down circuits, see the Device Operating
Conditions section.
This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can
be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of
power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power
supply DVDD3318_C.

an external pull-up can be used. For electrical specifications on the pull-up and and internal pull-down circuits, see the Device Operating

This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can
be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of
power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power
supply DVDD3318_C.

Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the signal name
highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured
function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different
types (ie., input versus output), the table reflects the pin function direction for that particular peripheral.
IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using
the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the
device is out of reset. During reset, all of the pins associated with these registers are pulled down. If the application requires a pull-up,
an external pull-up can be used. For electrical specifications on the pull-up and and internal pull-down circuits, see the Device Operating

MMC/SD1 data
I = Input, O = Output, I/O = Bidirectional, Z = High impedance, PWR = Supply voltage, GND = Ground, A = Analog signal.
Note: The pin type shown refers to the input, output or high-impedance state of the pin function when configured as the signal name
highlighted in bold. All multiplexed signals may enter a high-impedance state when the configured function is input-only or the configured
function supports high-Z operation. All GPIO signals can be used as input or output. For multiplexed pins where functions have different
types (ie., input versus output), the table reflects the pin function direction for that particular peripheral.
IPD = Internal Pulldown resistor; IPU = Internal Pullup resistor; CP[n] = configurable pull-up/pull-down (where n is the pin group) using
the PUPDENA and PUPDSEL registers in the System Module. The pull-up and pull-down control of these pins is not active until the
device is out of reset. During reset, all of the pins associated with these registers are pulled down. If the application requires a pull-up,
an external pull-up can be used. For electrical specifications on the pull-up and and internal pull-down circuits, see the Device Operating
Conditions section.
This signal is part of a dual-voltage IO group (A, B or C). These groups can be operated at 3.3V or 1.8V nominal. The three groups can
be operated at independent voltages but all pins withina group will operate at the same voltage. Group A operates at the voltage of
power supply DVDD3318_A. Group B operates at the voltage of power supply DVDD3318_B. Group C operates at the voltage of power
supply DVDD3318_C.

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

3 Device Configuration
3.1
Boot Modes
This device supports a variety of boot modes through an internal ARM ROM bootloader. This device does
not support dedicated hardware boot modes; therefore, all boot modes utilize the internal ARM ROM. The
input states of the BOOT pins are sampled and latched into the BOOTCFG register, which is part of the
system configuration (SYSCFG) module, when device reset is deasserted. Boot mode selection is
determined by the values of the BOOT pins.
See Using the OMAP-L1x8 Bootloader Application Report (SPRAB41) for more details on the ROM Boot
Loader.
The following boot modes are supported:
• NAND Flash boot
– 8-bit NAND
– 16-bit NAND (supported on ROM revisions after d800k002 -- see the bootloader documents
mentioned above to determine the ROM revision)
• NOR Flash boot
– NOR Direct boot (8-bit or 16-bit)
– NOR Legacy boot (8-bit or 16-bit)
– NOR AIS boot (8-bit or 16-bit)
• HPI Boot
• I2C0/I2C1 Boot
– EEPROM (Master Mode)
– External Host (Slave Mode)
• SPI0/ SPI1 Boot
– Serial Flash (Master Mode)
– SERIAL EEPROM (Master Mode)
– External Host (Slave Mode)
• UART0/UART1/UART2 Boot
– External Host
3.2
SYSCFG Module
The following system level features of the chip are controlled by the SYSCFG peripheral:
• Readable Device, Die, and Chip Revision ID
• Control of Pin Multiplexing
• Priority of bus accesses different bus masters in the system
• Capture at power on reset the chip BOOT pin values and make them available to software
• Control of the DeepSleep power management function
• Enable and selection of the programmable pin pullups and pulldowns
• Special case settings for peripherals:
– Locking of PLL controller settings
– Default burst sizes for EDMA3 transfer controllers
– Selection of the source for the eCAP module input capture (including on chip sources)
– McASP AMUTEIN selection and clearing of AMUTE status for the McASP
– Control of the reference clock source and other side-band signals for both of the integrated USB
PHYs
– Clock source selection for EMIFA
– DDR2 Controller PHY settings

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

The RTC provides an option for isolating the RTC_CVDD from the CVDD to reduce current leakage when the RTC is powered
independently. If these power supplies are not isolated (CTRL.SPLITPOWER=0), RTC_CVDD must be equal to or greater than CVDD.
If these power supplies are isolated (CTRL.SPLITPOWER=1), RTC_CVDD may be lower than CVDD.
DVDD18 must be powered even if all of the DVDD3318_x supplies are operated at 3.3V.
When an external crystal is used oscillator (OSC_VSS, RTC_VSS) ground must be kept separate from other grounds and connected
directly to the crystal load capacitor ground. These pins are shorted to VSS on the device itself and should not be connected to VSS on
the circuit board. If a crystal is not used and the clock input is driven directly, then the oscillator VSS may be connected to board ground.
These IO specifications apply to the dual-voltage IOs only and do not apply to DDR2/mDDR or SATA interfaces. DDR2/mDDR IOs are
1.8V IOs and adhere to the JESD79-2A standard.

The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its
transmission line effects must be taken into account. A transmission line with a delay of 2 ns or longer can be used to
produce the desired transmission line effect. The transmission line is intended as a load only. It is not necessary to
add or subtract the transmission line delay (2 ns or longer) from the data sheet timings.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the
device pin and the input signals are driven between 0V and the appropriate IO supply rail for the signal.

Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic
manner.

Power Supplies
Power-on Sequence
The device should be powered-on in the following order:
• 1) RTC (RTC_CVDD) may be powered from an external device (such as a battery) prior to all other
supplies being applied or powered-up at the same time as CVDD. If the RTC is not used, RTC_CVDD
should be connected to CVDD. RTC_CVDD should not be left unpowered while CVDD is powered.
• 2a) All variable 1.3V - 1.0V core logic supplies (CVDD)
• 2b) All static core logic supplies (RVDD, VDDA_12_PLL0, VDDA_12_PLL1, USB_CVDD ,
SATA_VDD). If voltage scaling is not used on the device, groups 2a) and 2b) can be controlled from
the same power supply and powered up together.
• 3) All static 1.8V IO supplies (DVDD18, DDR_DVDD18, USB0_VDDA18 , USB1_VDDA18 and
SATA_VDDR) and any of the LVCMOS IO supply groups used at 1.8V nominal (DVDD3318_A,
DVDD3318_B, or DVDD3318_C).
• 4) All analog 3.3V PHY supplies (USB0_VDDA33 and USB1_VDDA33; these are not required if both
USB0 and USB1 are not used) and any of the LVCMOS IO supply groups used at 3.3V nominal
(DVDD3318_A, DVDD3318_B, or DVDD3318_C).
There is no specific required voltage ramp rate for any of the supplies as long as the LVCMOS supplies
operated at 3.3V (DVDD3318_A, DVDD3318_B, or DVDD3318_C) never exceed the STATIC 1.8V
supplies by more than 2 volts.
RESET must be maintained active until all power supplies have reached their nominal values.
5.3.2
Power-off Sequence
The power supplies can be powered-off in any order as long as LVCMOS supplies operated at 3.3V
(DVDD3318_A, DVDD3318_B, or DVDD3318_C) never exceed static 1.8V supplies by more than 2 volts.
There is no specific required voltage ramp down rate for any of the supplies (except as required to meet
the above mentioned voltage condition).

Reset
Power-On Reset (POR)
A power-on reset (POR) is required to place the device in a known good state after power-up. Power-On
Reset is initiated by bringing RESET and TRST low at the same time. POR sets all of the device internal
logic to its default state. All pins are tri-stated with the exception of RESETOUT which remains active
through the reset sequence. RESETOUT is an output for use by other controllers in the system that
indicates the device is currently in reset.
RTCK is maintained active through a POR.

Crystal Oscillator or External Clock Input
The device includes two choices to provide an external clock input, which is fed to the on-chip PLLs to
generate high-frequency system clocks. These options are illustrated in Figure 5-6 and Figure 5-7. For
input clock frequencies between 12 and 20 MHz, a crystal with 80 ohm max ESR is recommended. For
input clock frequencies between 20 and 30 MHz, a crystal with 60 ohm max ESR is recommended.
Typical load capacitance values are 10-20 pF, where the load capacitance is the series combination of C1
and C2.
Figure 5-6 illustrates the option that uses on-chip 1.2V oscillator with external crystal circuit. Figure 5-7
illustrates the option that uses an external 1.2V clock input.

Clock PLLs
The device has two PLL controllers that provide clocks to different parts of the system. PLL0 provides
clocks (though various dividers) to most of the components of the device. PLL1 provides clocks to the
mDDR/DDR2 Controller and provides an alternate clock source for the ASYNC3 clock domain. This allows
the peripherals on the ASYNC3 clock domain to be immune to frequency scaling operation on PLL0.
The PLL controller provides the following:
• Glitch-Free Transitions (on changing clock settings)
• Domain Clocks Alignment
• Clock Gating
• PLL power down
The various clock outputs given by the controller are as follows:
• Domain Clocks: SYSCLK [1:n]
• Auxiliary Clock from reference clock source: AUXCLK
Various dividers that can be used are as follows:
• Post-PLL Divider: POSTDIV
• SYSCLK Divider: D1, ¼, Dn
Various other controls supported are as follows:
• PLL Multiplier Control: PLLM
• Software programmable PLL Bypass: PLLEN

The input to the PLL is either from the on-chip oscillator or from an external clock on the OSCIN pin. PLL0
outputs seven clocks that have programmable divider options. PLL1 outputs three clocks that have
programmable divider options. Figure 5-9 illustrates the high-level view of the PLL Topology.
The PLLs are disabled by default after a device reset. They must be configured by software according to
the allowable operating conditions listed in Table 5-4 before enabling the device to run from the PLL by
setting PLLEN = 1.

The multiplier values must be chosen such that the PLL output frequency (at PLLOUT) is between 300 and 600 MHz, but the frequency
going into the SYSCLK dividers (after the post divider) cannot exceed the maximum clock frequency defined for the device at a given
voltage operating point.
5.6.2
Device Clock Generation
PLL0 is controlled by PLL Controller 0 and PLL1 is controlled by PLL Controller 1. PLLC0 and PLLC1
manage the clock ratios, alignment, and gating for the system clocks to the chip. The PLLCs are
responsible for controlling all modes of the PLL through software, in terms of pre-division of the clock
inputs (PLLC0 only), multiply factors within the PLLs, and post-division for each of the chip-level clocks
from the PLLs outputs. PLLC0 also controls reset propagation through the chip, clock alignment, and test
points.
PLLC0 provides clocks for the majority of the system but PLLC1 provides clocks to the mDDR/DDR2
Controller and the ASYNC3 clock domain to provide frequency scaling immunity to a defined set or
peripherals. The ASYNC3 clock domain can either derive its clock from PLL1_SYSCLK2 (for frequency
scaling immunity from PLL0) or from PLL0_SYSCLK2 (for synchronous timing with PLL0) depending on
the application requirements. In addition, some peripherals have specific clock options independent of the
ASYNC clock domain.
5.6.3
Dynamic Voltage and Frequency Scaling (DVFS)
The processor supports multiple operating points by scaling voltage and frequency to minimize power
consumption for a given level of processor performance.
Frequency scaling is achieved by modifying the setting of the PLL controllers’ multipliers, post-dividers
(POSTDIV), and system clock dividers (SYSCLKn). Modification of the POSTDIV and SYSCLK values
does not require relocking the PLL and provides lower latency to switch between operating points, but at
the expense of the frequencies being limited by the integer divide values (only the divide values are
altered the PLL multiplier is left unmodified). Non integer divide frequency values can be achieved by
changing both the multiplier and the divide values, but when the PLL multiplier is changed the PLL must
relock, incurring additional latency to change between operating points. Detailed information on modifying
the PLL Controller settings can be found in the SMOMAPL138B Applications Processor System
Reference Guide - SPRUGM7 .

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

points.

Some interfaces have specific limitations on supported modes/speeds at each operating point. See the

TI provides software components (called the Power Manager) to perform DVFS and abstract the task from
the user. The Power Manager controls changing operating points (both frequency and voltage) and
handles the related tasks involved such as informing/controlling peripherals to provide graceful transitions
between operating points. The Power Manager is bundled as a component of DSP/BIOS.

SLVSAQ9 – JANUARY 2011
Interrupts
The device has a large number of interrupts to service the needs of its many peripherals and subsystems.
Both the ARM and C674x CPUs are capable of servicing these interrupts equally. The interrupts can be
selectively enabled or disabled in either of the controllers. Also, the ARM and DSP can communicate with
each other through interrupts controlled by registers in the SYSCFG module.
5.7.1
ARM CPU Interrupts
The ARM9 CPU core supports 2 direct interrupts: FIQ and IRQ. The ARM Interrupt Controller (AINTC)
extends the number of interrupts to 100, and provides features like programmable masking, priority,
hardware nesting support, and interrupt vector generation.
5.7.1.1
ARM Interrupt Controller (AINTC) Interrupt Signal Hierarchy
The ARM Interrupt controller organizes interrupts into the following hierarchy:
• Peripheral Interrupt Requests
– Individual Interrupt Sources from Peripherals
• 101 System Interrupts
– One or more Peripheral Interrupt Requests are combined (fixed configuration) to generate a
System Interrupt.
– After prioritization, the AINTC will provide an interrupt vector based unique to each System Interrupt
• 32 Interrupt Channels
– Each System Interrupt is mapped to one of the 32 Interrupt Channels
– Channel Number determines the first level of prioritization, Channel 0 is highest priority and 31
lowest.
– If more than one system interrupt is mapped to a channel, priority within the channel is determined
by system interrupt number (0 highest priority)
• Host Interrupts (FIQ and IRQ)
– Interrupt Channels 0 and 1 generate the ARM FIQ interrupt
– Interrupt Channels 2 through 31 Generate the ARM IRQ interrupt
• Debug Interrupts
– Two Debug Interrupts are supported and can be used to trigger events in the debug subsystem
– Sources can be selected from any of the System Interrupts or Host Interrupts
5.7.1.2
AINTC Hardware Vector Generation
The AINTC also generates an interrupt vector in hardware for both IRQ and FIQ host interrupts. This may
be used to accelerate interrupt dispatch. A unique vector is generated for each of the 100 system
interrupts. The vector is computed in hardware as:
VECTOR = BASE + (SYSTEM INTERRUPT NUMBER × SIZE)
Where BASE and SIZE are programmable. The computed vector is a 32-bit address which may
dispatched to using a single instruction of type LDR PC, [PC, #-<offset_12>] at the FIQ and IRQ vector
locations (0xFFFF0018 and 0xFFFF001C respectively).
5.7.1.3
AINTC Hardware Interrupt Nesting Support
Interrupt nesting occurs when an interrupt service routine re-enables interrupts, to allow the CPU to
interrupt the ISR if a higher priority event occurs. The AINTC provides hardware support to facilitate
interrupt nesting. It supports both global and per host interrupt (FIQ and IRQ in this case) automatic

nesting. If enabled, the AINTC will automatically update an internal nesting register that temporarily masks
interrupts at and below the priority of the current interrupt channel. Then if the ISR re-enables interrupts;
only higher priority channels will be able to interrupt it. The nesting level is restored by the ISR by writing
to the nesting level register on completion. Support for nesting can be enabled/disabled by software, with
the option of automatic nesting on a global or per host interrupt basis; or manual nesting.

DSP Interrupts
The C674x DSP interrupt controller combines device events into 12 prioritized interrupts. The source for
each of the 12 CPU interrupts is user programmable and is listed in Table 5-8. Also, the interrupt
controller controls the generation of the CPU exceptions, NMI, and emulation interrupts. Table 5-9
summarizes the C674x interrupt controller registers and memory locations.

Power and Sleep Controller (PSC)
The Power and Sleep Controllers (PSC) are responsible for managing transitions of system power on/off,
clock on/off, resets (device level and module level). It is used primarily to provide granular power control
for on chip modules (peripherals and CPU). A PSC module consists of a Global PSC (GPSC) and a set of
Local PSCs (LPSCs). The GPSC contains memory mapped registers, PSC interrupts, a state machine for
each peripheral/module it controls. An LPSC is associated with every module that is controlled by the PSC
and provides clock and reset control.
The PSC includes the following features:
• Provides a software interface to:
– Control module clock enable/disable
– Control module reset
– Control CPU local reset
• Supports IcePick emulation features: power, clock and reset
PSC0 controls 16 local PSCs.
PSC1 controls 32 local PSCs.

REGISTER DESCRIPTION
Power Domain and Module Topology
The device includes two PSC modules.
Each PSC module controls clock states for several of the on chip modules, controllers and interconnect
components. Table 5-11 and Table 5-12 lists the set of peripherals/modules that are controlled by the
PSC, the power domain they are associated with, the LPSC assignment and the default (power-on reset)
module states. The module states and terminology are defined in Section 5.8.1.2.

5.8.1.1
SLVSAQ9 – JANUARY 2011
Power Domain States
A power domain can only be in one of the two states: ON or OFF, defined as follows:
• ON: power to the domain is on
• OFF: power to the domain is off
For both PSC0 and PSC1, the Always ON domain, or PD0 power domain, is always in the ON state when
the chip is powered-on. This domain is not programmable to OFF state.
• On PSC0 PD1/PD_DSP Domain: Controls the sleep state for DSP L1 and L2 Memories
• On PSC1 PD1/PD_SHRAM Domain: Controls the sleep state for the 128K Shared RAM
5.8.1.2
Module States
The PSC defines several possible states for a module. This states are essentially a combination of the
module reset asserted or de-asserted and module clock on/enabled or off/disabled. The module states are
defined in Table 5-13.
Table 5-13. Module States
Module State
Module Reset
Module
Clock
Module State Definition
Enable
De-asserted
On
A module in the enable state has its module reset de-asserted and it has its clock on.
This is the normal operational state for a given module
Disable
De-asserted
Off
A module in the disabled state has its module reset de-asserted and it has its module
clock off. This state is typically used for disabling a module clock to save power. The
device is designed in full static CMOS, so when you stop a module clock, it retains the
module’s state. When the clock is restarted, the module resumes operating from the
stopping point.
SyncReset
Asserted
On
A module state in the SyncReset state has its module reset asserted and it has its
clock on. Generally, software is not expected to initiate this state
SwRstDisable
Asserted
Off
A module in the SwResetDisable state has its module reset asserted and it has its
clock disabled. After initial power-on, several modules come up in the SwRstDisable
state. Generally, software is not expected to initiate this state
Auto Sleep
De-asserted
Off
A module in the Auto Sleep state also has its module reset de-asserted and its module
clock disabled, similar to the Disable state. However this is a special state, once a
module is configured in this state by software, it can “automatically” transition to
“Enable” state whenever there is an internal read/write request made to it, and after
servicing the request it will “automatically” transition into the sleep state (with module
reset re de-asserted and module clock disabled), without any software intervention.
The transition from sleep to enabled and back to sleep state has some cycle latency
associated with it. It is not envisioned to use this mode when peripherals are fully
operational and moving data.
Auto Wake
De-asserted
Off
A module in the Auto Wake state also has its module reset de-asserted and its module
clock disabled, similar to the Disable state. However this is a special state, once a
module is configured in this state by software, it will “automatically” transition to
“Enable” state whenever there is an internal read/write request made to it, and will
remain in the “Enabled” state from then on (with module reset re de-asserted and
module clock on), without any software intervention. The transition from sleep to
enabled state has some cycle latency associated with it. It is not envisioned to use this
mode when peripherals are fully operational and moving data.

EDMA
The EDMA controller handles all data transfers between memories and the device slave peripherals on
the device. These data transfers include cache servicing, non-cacheable memory accesses,
user-programmed data transfers, and host accesses.
5.9.1
EDMA3 Channel Synchronization Events
Each EDMA channel controller supports up to 32 channels which service peripherals and memory.
Table 5-14 lists the source of the EDMA synchronization events associated with each of the
programmable EDMA channels.

On previous architectures, the EDMA3TC priority was controlled by the queue priority register (QUEPRI) in the EDMA3CC
memory-map. However for this device, the priority control for the transfer controllers is controlled by the chip-level registers in the
System Configuration Module. You should use the chip-level registers and not QUEPRI to configure the TC priority.

5.10 External Memory Interface A (EMIFA)
EMIFA is one of two external memory interfaces supported on the device. It is primarily intended to
support asynchronous memory types, such as NAND and NOR flash and Asynchronous SRAM. However
on this device, EMIFA also provides a secondary interface to SDRAM.
5.10.1 EMIFA Asynchronous Memory Support
EMIFA supports asynchronous:
• SRAM memories
• NAND Flash memories
• NOR Flash memories
The EMIFA data bus width is up to 16-bits.The device supports up to 23 address lines and two external
wait/interrupt inputs. Up to four asynchronous chip selects are supported by EMIFA (EMA_CS[5:2]).
Each chip select has the following individually programmable attributes:
• Data Bus Width
• Read cycle timings: setup, hold, strobe
• Write cycle timings: setup, hold, strobe
• Bus turn around time
• Extended Wait Option With Programmable Timeout
• Select Strobe Option
• NAND flash controller supports 1-bit and 4-bit ECC calculation on blocks of 512 bytes.
5.10.2 EMIFA Synchronous DRAM Memory Support
The device supports 16-bit SDRAM in addition to the asynchronous memories listed in Section 5.10.1. It
has a single SDRAM chip select (EMA_CS[0]). SDRAM configurations that are supported are:
• One, Two, and Four Bank SDRAM devices
• Devices with Eight, Nine, Ten, and Eleven Column Address
• CAS Latency of two or three clock cycles
• Sixteen Bit Data Bus Width
Additionally, the SDRAM interface of EMIFA supports placing the SDRAM in Self Refresh and Powerdown
Modes. Self Refresh mode allows the SDRAM to be put into a low power state while still retaining memory
contents; since the SDRAM will continue to refresh itself even without clocks from the device. Powerdown
mode achieves even lower power, except the device must periodically wake the SDRAM up and issue
refreshes if data retention is required.
Finally, note that the EMIFA does not support Mobile SDRAM devices.
Table 5-19 shows the supported SDRAM configurations for EMIFA.

The shaded cells indicate configurations that are possible on the EMIFA interface but as of this writing SDRAM memories capable of
supporting these densities are not available in the market.
5.10.3 EMIFA SDRAM Loading Limitations
EMIFA supports SDRAM up to 100 MHz with up to two SDRAM or asynchronous memory loads.
Additional loads will limit the SDRAM operation to lower speeds and the maximum speed should be
confirmed by board simulation using IBIS models.
5.10.4 EMIFA Connection Examples
Figure 5-10 illustrates an example of how SDRAM, NOR, and NAND flash devices might be connected to
EMIFA of a SMOMAPL138B device simultaneously. The SDRAM chip select must be EMA_CS[0]. Note
that the NOR flash is connected to EMA_CS[2] and the NAND flash is connected to EMA_CS[3] in this
example. Note that any type of asynchronous memory may be connected to EMA_CS[5:2].
The on-chip bootloader makes some assumptions on which chip select the contains the boot image, and
this depends on the boot mode. For NOR boot mode; the on-chip bootloader requires that the image be
stored in NOR flash on EMA_CS[2]. For NAND boot mode, the bootloader requires that the boot image is
stored in NAND flash on EMA_CS[3]. It is always possible to have the image span multiple chip selects,
but this must be supported by second stage boot code stored in the external flash.

A likely use case with more than one EMIFA chip select used for NAND flash is illustrated in Figure 5-11.
This figure shows how two multiplane NAND flash devices with two chip selects each would connect to the
EMIFA. In this case if NAND is the boot memory, then the boot image needs to be stored in the NAND
area selected by EMA_CS[3]. Part of the application image could spill over into the NAND regions
selected by other EMIFA chip selects; but would rely on the code stored in the EMA_CS[3] area to
bootload it.

Setup before end of STROBE phase (if no extended wait states are inserted) by which EM_WAIT must be asserted to add extended
wait states. Figure 5-16 and Figure 5-17 describe EMIF transactions that include extended wait states inserted during the STROBE
phase. However, cycles inserted as part of this extended wait period should not be counted; the 4E requirement is to the start of where
the HOLD phase would begin if there were no extended wait cycles.

5.11.3 DDR2/mDDR Interface
This section provides the timing specification for the DDR2/mDDR interface as a PCB design and
manufacturing specification. The design rules constrain PCB trace length, PCB trace skew, signal
integrity, cross-talk, and signal timing. These rules, when followed, result in a reliable DDR2/mDDR
memory system without the need for a complex timing closure process. For more information regarding
guidelines for using this DDR2/mDDR specification, Understanding TI's PCB Routing Rule-Based DDR2
Timing Specification (SPRAAV0).
5.11.3.1 DDR2/mDDR Interface Schematic
Figure 5-18 shows the DDR2/mDDR interface schematic for a single-memory DDR2/mDDR system. The
dual-memory system shown in Figure 5-19. Pin numbers for the device can be obtained from the pin
description section.

5.11.3.2 Compatible JEDEC DDR2/mDDR Devices
Table 5-27 shows the parameters of the JEDEC DDR2/mDDR devices that are compatible with this
interface. Generally, the DDR2/mDDR interface is compatible with x16 DDR2/mDDR-400 speed grade
DDR2/mDDR devices.
The device also supports JEDEC DDR2/mDDR x8 devices in the dual chip configuration. In this case, one
chip supplies the upper byte and the second chip supplies the lower byte. Addresses and most control
signals are shared just like regular dual chip memory configurations.

5.11.3.4 Placement
Figure 5-19 shows the required placement for the device as well as the DDR2/mDDR devices. The
dimensions for Figure 5-20 are defined in Table 5-30. The placement does not restrict the side of the PCB
that the devices are mounted on. The ultimate purpose of the placement is to limit the maximum trace
lengths and allow for proper routing space. For single-memory DDR2/mDDR systems, the second
DDR2/mDDR device is omitted from the placement.

The region of the PCB used for the DDR2/mDDR circuitry must be isolated from other signals. The
DDR2/mDDR keep out region is defined for this purpose and is shown in Figure 5-21. The size of this
region varies with the placement and DDR routing. Additional clearances required for the keep out region
are shown in Table 5-30.

provided they are routed on layers separated from DDR2/mDDR
signal layers by a ground layer. No breaks should be allowed in the
reference ground layers in this region. In addition, the 1.8 V power
plane should cover the entire keep out region.

5.11.3.7 High-Speed Bypass Capacitors
High-speed (HS) bypass capacitors are critical for proper DDR2/mDDR interface operation. It is
particularly important to minimize the parasitic series inductance of the HS bypass cap, Soc /DDR2/mDDR
power, and Soc /DDR2/mDDR ground connections. Table 5-32 contains the specification for the HS
bypass capacitors as well as for the power connections on the PCB.

5.11.3.12 MDDR/DDR2 Boundary Scan Limitations
Due to DDR implementation and timing restrictions, it was not possible to place boundary scan cells
between core logic and the IO like boundary scan cells for other IO. Instead, the boundary scan cells are
tapped-off to the DDR PHY and there is the equivalent of a multiplexer inside the DDR PHY which selects
between functional and boundary scan paths.
The implication for boundary scan is that the DDR pins will not support the SAMPLE function of the output
enable cells on the DDR pins and this is a violation of IEEE 1149.1. Full EXTEST and PRELOAD
capability is still available.

5.12 Memory Protection Units
The MPU performs memory protection checking. It receives requests from a bus master in the system and
checks the address against the fixed and programmable regions to see if the access is allowed. If allowed,
the transfer is passed unmodified to its output bus (to the targeted address). If the transfer is illegal (fails
the protection check) then the MPU does not pass the transfer to the output bus but rather services the
transfer internally back to the input bus (to prevent a hang) returning the fault status to the requestor as
well as generating an interrupt about the fault. The following features are supported by the MPU:
• Provides memory protection for fixed and programmable address ranges.
• Supports multiple programmable address region.
• Supports secure and debug access privileges.
• Supports read, write, and execute access privileges.
• Supports privid(8) associations with ranges.
• Generates an interrupt when there is a protection violation, and saves violating transfer parameters.
• MMR access is also protected.

5.14 Serial ATA Controller (SATA)
The Serial ATA Controller (SATA) provides a single HBA port operating in AHCI mode and is used to
interface to data storage devices at both 1.5 Gbits/second and 3.0 Gbits/second line speeds. AHCI
describes a system memory structure that contains a generic area for control and status, and a table of
entries describing a command list where each command list entry contains information necessary to
program an SATA device, and a pointer to a descriptor table for transferring data between system memory
and the device.
The SATA Controller supports the following features:
•
•
•
•
•
•
•
•

5.14.2 1. SATA Interface
This section provides the timing specification for the SATA interface as a PCB design and manufacturing
specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. TI has performed the simulation and system design work to ensure the SATA interface
requirements are met.

5.14.2.4 Routing Specifications
The SATA data signal traces are edge-coupled and must be routed to achieve exactly 100 Ohms
differential impedance. This is impacted by trace width, trace spacing, distance between planes, and
dielectric material. Verify with a proper PCB manufacturing tool that the trace geometry for both data
signal pairs results in exactly 100 ohms differential impedance traces. Table 5-47 shows the routing
specifications for the data and REFCLK signals .

5.14.2.6 SATA Interface Clock Source requirements
A high-quality, low-jitter differential clock source is required for the SATA PHY. The SATA interface
requires a LVDS differential clock source to be provided at signals SATA_REFCLKP and
SATA_REFCLKN. The clock source should be placed physically as close to the processor as possible.

5.15 Multichannel Audio Serial Port (McASP)
The McASP serial port is specifically designed for multichannel audio applications. Its key features are:
• Flexible clock and frame sync generation logic and on-chip dividers
• Up to sixteen transmit or receive data pins and serializers
• Large number of serial data format options, including:
– TDM Frames with 2 to 32 time slots per frame (periodic) or 1 slot per frame (burst)
– Time slots of 8,12,16, 20, 24, 28, and 32 bits
– First bit delay 0, 1, or 2 clocks
– MSB or LSB first bit order
– Left- or right-aligned data words within time slots
• DIT Mode with 384-bit Channel Status and 384-bit User Data registers
• Extensive error checking and mute generation logic
• All unused pins GPIO-capable
•
•
Transmit & Receive FIFO Buffers allow the McASP to operate at a higher sample rate by making it
more tolerant to DMA latency.

5.16 Multichannel Buffered Serial Port (McBSP)
The McBSP provides these functions:
• Full-duplex communication
• Double-buffered data registers, which allow a continuous data stream
• Independent framing and clocking for receive and transmit
• Direct interface to industry-standard codecs, analog interface chips (AICs), and other serially
connected analog-to-digital (A/D) and digital-to-analog (D/A) devices
• External shift clock or an internal, programmable frequency shift clock for data transfer
• Transmit & Receive FIFO Buffers allow the McBSP to operate at a higher sample rate by making it
more tolerant to DMA latency
If internal clock source is used, the CLKGDV field of the Sample Rate Generator Register (SRGR) must
always be set to a value of 1 or greater.

Use whichever value is greater. Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clock

Minimum delay times also represent minimum output hold times.
Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clock source. Minimum CLKR/X cycle times
are based on internal logic speed; the maximum usable speed may be lower due to EDMA limitations and AC timing requirements.

Use whichever value is greater.

S = sample rate generator input clock = P if CLKSM = 1 (P = ASYNC period)
S = sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)
H = CLKX high pulse width = (CLKGDV/2 + 1) * S if CLKGDV is even
H = (CLKGDV + 1)/2 * S if CLKGDV is odd
L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
L = (CLKGDV + 1)/2 * S if CLKGDV is odd
CLKGDV should be set appropriately to ensure the McBSP bit rate does not exceed the maximum limit (see (4) above).
Extra delay from CLKX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.
if DXENA = 0, then D1 = D2 = 0
if DXENA = 1, then D1 = 6P, D2 = 12P

CLKRP = CLKXP = FSRP = FSXP = 0. If polarity of any of the signals is inverted, then the timing references of that signal are also

Minimum delay times also represent minimum output hold times.
Minimum CLKR/X cycle times must be met, even when CLKR/X is generated by an internal clock source. Minimum CLKR/X cycle times
are based on internal logic speed; the maximum usable speed may be lower due to EDMA limitations and AC timing requirements.
P = AYNC3 period in ns. For example, when the ASYNC clock domain is running at 100 MHz, use 10 ns.
Use whichever value is greater.
C = H or L
S = sample rate generator input clock = P if CLKSM = 1 (P = ASYNC period)
S = sample rate generator input clock = P_clks if CLKSM = 0 (P_clks = CLKS period)

L = CLKX low pulse width = (CLKGDV/2) * S if CLKGDV is even
L = (CLKGDV + 1)/2 * S if CLKGDV is odd
CLKGDV should be set appropriately to ensure the McBSP bit rate does not exceed the maximum limit (see (4) above).
Extra delay from CLKX high to DX valid applies only to the first data bit of a device, if and only if DXENA = 1 in SPCR.
if DXENA = 0, then D1 = D2 = 0

5.17 Serial Peripheral Interface Ports (SPI0, SPI1)
Figure 5-36 is a block diagram of the SPI module, which is a simple shift register and buffer plus control
logic. Data is written to the shift register before transmission occurs and is read from the buffer at the end
of transmission. The SPI can operate either as a master, in which case, it initiates a transfer and drives
the SPIx_CLK pin, or as a slave. Four clock phase and polarity options are supported as well as many
data formatting options.

Figure 5-36. Block Diagram of SPI Module
The SPI supports 3-, 4-, and 5-pin operation with three basic pins (SPIx_CLK, SPIx_SIMO, and
SPIx_SOMI) and two optional pins (SPIx_SCS, SPIx_ENA).
The optional SPIx_SCS (Slave Chip Select) pin is most useful to enable in slave mode when there are
other slave devices on the same SPI port. The device will only shift data and drive the SPIx_SOMI pin
when SPIx_SCS is held low.
In slave mode, SPIx_ENA is an optional output. The SPIx_ENA output provides the status of the internal
transmit buffer (SPIDAT0/1 registers). In four-pin mode with the enable option, SPIx_ENA is asserted only
when the transmit buffer is full, indicating that the slave is ready to begin another transfer. In five-pin
mode, the SPIx_ENA is additionally qualified by SPIx_SCS being asserted. This allows a single
handshake line to be shared by multiple slaves on the same SPI bus.
In master mode, the SPIx_ENA pin is an optional input and the master can be configured to delay the start
of the next transfer until the slave asserts SPIx_ENA. The addition of this handshake signal simplifies SPI
communications and, on average, increases SPI bus throughput since the master does not need to delay
each transfer long enough to allow for the worst-case latency of the slave device. Instead, each transfer
can begin as soon as both the master and slave have actually serviced the previous SPI transfer.

SPI0_ENA is driven low after the transmission completes if the SPIINT0.ENABLE_HIGHZ bit is programmed to 0. Otherwise it is tri-stated. If tri-stated, an external pullup resistor should
be used to provide a valid level to the master. This option is useful when tying several SPI slave devices to a single master.

SPI1_ENA is driven low after the transmission completes if the SPIINT0.ENABLE_HIGHZ bit is programmed to 0. Otherwise it is tri-stated. If tri-stated, an external pullup resistor should
be used to provide a valid level to the master. This option is useful when tying several SPI slave devices to a single master.

U = UART baud time = 1/programmed baud rate.
D = UART input clock in MHz.
For UART0, the UART input clock is SYSCLK2.
For UART1 or UART2, the UART input clock is ASYNC3 (either PLL0_SYCLK2 or PLL1_SYSCLK2).
E = UART divisor x UART sampling rate. The UART divisor is set through the UART divisor latch registers (DLL and DLH). The UART
sampling rate is set through the over-sampling mode select bit (OSM_SEL) of the UART mode definition register (MDR).
Baud rate is not indicative of data rate. Actual data rate will be limited by system factors such as EDMA loading, EMIF/DDR loading,
system frequency, etc.

5.20 Universal Serial Bus OTG Controller (USB0) [USB2.0 OTG]
The USB2.0 peripheral supports the following features:
• USB 2.0 peripheral at speeds high speed (HS: 480 Mb/s) and full speed (FS: 12 Mb/s)
• USB 2.0 host at speeds HS, FS, and low speed (LS: 1.5 Mb/s)
• All transfer modes (control, bulk, interrupt, and isochronous)
• 4 Transmit (TX) and 4 Receive (RX) endpoints in addition to endpoint 0
• FIFO RAM
– 4K endpoint
– Programmable size
• Integrated USB 2.0 High Speed PHY
• Connects to a standard Charge Pump for VBUS 5 V generation
• RNDIS mode for accelerating RNDIS type protocols using short packet termination over USB
Important Notice: The USB0 controller module clock (PLL0_SYSCLK2) must be greater than 30 MHz for
proper operation of the USB controller. A clock rate of 60 MHz or greater is recommended to avoid data
throughput reduction.
Table 5-92 is the list of USB OTG registers.

5.22 Ethernet Media Access Controller (EMAC)
The Ethernet Media Access Controller (EMAC) provides an efficient interface between device and the
network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbits/second (Mbps) and 100 Mbps
in either half- or full-duplex mode, with hardware flow control and quality of service (QOS) support.
The EMAC controls the flow of packet data from the device to the PHY. The MDIO module controls PHY
configuration and status monitoring.
Both the EMAC and the MDIO modules interface to the device through a custom interface that allows
efficient data transmission and reception. This custom interface is referred to as the EMAC control
module, and is considered integral to the EMAC/MDIO peripheral. The control module is also used to
multiplex and control interrupts.

5.23 Management Data Input/Output (MDIO)
The Management Data Input/Output (MDIO) module continuously polls all 32 MDIO addresses in order to
enumerate all PHY devices in the system.
The Management Data Input/Output (MDIO) module implements the 802.3 serial management interface to
interrogate and control Ethernet PHY(s) using a shared two-wire bus. Host software uses the MDIO
module to configure the auto-negotiation parameters of each PHY attached to the EMAC, retrieve the
negotiation results, and configure required parameters in the EMAC module for correct operation. The
module is designed to allow almost transparent operation of the MDIO interface, with very little
maintenance from the core processor. Only one PHY may be connected at any given time.

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

Frame-to-frame timing is derived through the following parameters in the LCD (RASTER_TIMING_1)
register:
• Vertical front porch (VFP)
• Vertical sync pulse width (VSW)
• Vertical back porch (VBP)
• Lines per panel (LPP)
Line-to-line timing is derived through the following parameters in the LCD (RASTER_TIMING_0) register:
• Horizontal front porch (HFP)
• Horizontal sync pulse width (HSW)
• Horizontal back porch (HBP)
• Pixels per panel (PPL)
LCD_AC_ENB_CS timing is derived through the following parameter in the LCD (RASTER_TIMING_2)
register:
• AC bias frequency (ACB)
The display format produced in raster mode is shown in Figure 5-62. An entire frame is delivered one line
at a time. The first line delivered starts at data pixel (1, 1) and ends at data pixel (P, 1). The last line
delivered starts at data pixel (1, L) and ends at data pixel (P, L). The beginning of each new frame is
denoted by the activation of I/O signal LCD_VSYNC. The beginning of each new line is denoted by the
activation of I/O signal LCD_HSYNC.

5.25 Host-Port Interface (UHPI)
5.25.1 HPI Device-Specific Information
The device includes a user-configurable 16-bit Host-port interface (HPI16).
The host port interface (UHPI) provides a parallel port interface through which an external host processor
can directly access the processor's resources (configuration and program/data memories). The external
host device is asynchronous to the CPU clock and functions as a master to the HPI interface. The UHPI
enables a host device and the processor to exchange information via internal or external memory.
Dedicated address (HPIA) and data (HPID) registers within the UHPI provide the data path between the
external host interface and the processor resources. A UHPI control register (HPIC) is available to the
host and the CPU for various configuration and interrupt functions.

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

XOR HDS2)] OR UHPI_HCS.
B. Depending on the type of write or read operation (HPID without auto-incrementing; HPIA, HPIC, or HPID with
auto-incrementing) and the state of the FIFO, transitions on UHPI_HRDY may or may not occur.
C. UHPI_HCS reflects typical UHPI_HCS behavior when UHPI_HSTROBE assertion is caused by UHPI_HDS1 or
UHPI_HDS2. UHPI_HCS timing requirements are reflected by parameters for UHPI_HSTROBE.

UHPI_HRDY(B)
A. UHPI_HSTROBE refers to the following logical operation on UHPI_HCS, UHPI_HDS1, and UHPI_HDS2: [NOT(HDS1 XOR HDS2)] OR
UHPI_HCS.
B. Depending on the type of write or read operation (HPID without auto-incrementing; HPIA, HPIC, or HPID with auto-incrementing) and the
state of the FIFO, transitions on UHPI_HRDY may or may not occur.
C. UHPI_HCS reflects typical UHPI_HCS behavior when UHPI_HSTROBE assertion is caused by UHPI_HDS1 or UHPI_HDS2. UHPI_HCS
timing requirements are reflected by parameters for UHPI_HSTROBE.
D The diagram above assumes UHPI_HAS has been pulled high.

5.26 Universal Parallel Port (uPP)
The Universal Parallel Port (uPP) peripheral is a multichannel, high-speed parallel interface with dedicated
data lines and minimal control signals. It is designed to interface cleanly with high-speed analog-to-digital
converters (ADCs) or digital-to-analog converters (DACs) with up to 16-bit data width (per channel). It may
also be interconnected with field-programmable gate arrays (FPGAs) or other uPP devices to achieve
high-speed digital data transfer. It can operate in receive mode, transmit mode, or duplex mode, in which
its individual channels operate in opposite directions.
The uPP peripheral includes an internal DMA controller to maximize throughput and minimize CPU
overhead during high-speed data transmission. All uPP transactions use the internal DMA to provide data
to or retrieve data from the I/O channels. The DMA controller includes two DMA channels, which typically
service separate I/O channels. The uPP peripheral also supports data interleave mode, in which all DMA
resources service a single I/O channel. In this mode, only one I/O channel may be used.
The features of the uPP include:
• Programmable data width per channel (from 8 to 16 bits inclusive)
• Programmable data justification
– Right-justify with zero extend
– Right-justify with sign extend
– Left-justify with zero fill
• Supports multiplexing of interleaved data during SDR transmit
• Optional frame START signal with programmable polarity
• Optional data ENABLE signal with programmable polarity
• Optional synchronization WAIT signal with programmable polarity
• Single Data Rate (SDR) or Double data Rate (DDR, interleaved) interface
– Supports multiplexing of interleaved data during SDR transmit
– Supports demultiplexing and multiplexing of interleaved data during DDR transfers

5.28 Enhanced Capture (eCAP) Peripheral
The device contains up to three enhanced capture (eCAP) modules. Figure 5-78 shows a functional block
diagram of a module.
Uses for ECAP include:
• Speed measurements of rotating machinery (e.g. toothed sprockets sensed via Hall sensors)
• Elapsed time measurements between position sensor triggers
• Period and duty cycle measurements of pulse train signals
• Decoding current or voltage amplitude derived from duty cycle encoded current/voltage sensors
The ECAP module described in this specification includes the following features:
• 32 bit time base
• 4 event time-stamp registers (each 32 bits)
• Edge polarity selection for up to 4 sequenced time-stamp capture events
• Interrupt on either of the 4 events
• Single shot capture of up to 4 event time-stamps
• Continuous mode capture of time-stamps in a 4 deep circular buffer
• Absolute time-stamp capture
• Difference mode time-stamp capture
• All the above resources are dedicated to a single input pin
The eCAP modules are clocked at the ASYNC3 clock domain rate.

5.31 Real Time Clock (RTC)
The RTC provides a time reference to an application running on the device. The current date and time is
tracked in a set of counter registers that update once per second. The time can be represented in 12-hour
or 24-hour mode. The calendar and time registers are buffered during reads and writes so that updates do
not interfere with the accuracy of the time and date.
Alarms are available to interrupt the CPU at a particular time, or at periodic time intervals, such as once
per minute or once per day. In addition, the RTC can interrupt the CPU every time the calendar and time
registers are updated, or at programmable periodic intervals.
The real-time clock (RTC) provides the following features:
• 100-year calendar (xx00 to xx99)
• Counts seconds, minutes, hours, day of the week, date, month, and year with leap year compensation
• Binary-coded-decimal (BCD) representation of time, calendar, and alarm
• 12-hour clock mode (with AM and PM) or 24-hour clock mode
• Alarm interrupt
• Periodic interrupt
• Single interrupt to the CPU
• Supports external 32.768-kHz crystal or external clock source of the same frequency
• Separate isolated power supply
Figure 5-84 shows a block diagram of the RTC.

5.31.1 Clock Source
The clock reference for the RTC is an external 32.768-kHz crystal or an external clock source of the same
frequency. The RTC also has a separate power supply that is isolated from the rest of the system. When
the CPU and other peripherals are without power, the RTC can remain powered to preserve the current
time and calendar information. Even if the RTC is not used, it must remain powered when the rest of the
device is powered.
The source for the RTC reference clock may be provided by a crystal or by an external clock source. The
RTC has an internal oscillator buffer to support direct operation with a crystal. The crystal is connected
between pins RTC_XI and RTC_XO. RTC_XI is the input to the on-chip oscillator and RTC_XO is the
output from the oscillator back to the crystal.
An external 32.768-kHz clock source may be used instead of a crystal. In such a case, the clock source is
connected to RTC_XI, and RTC_XO is left unconnected.
If the RTC is not used, the RTC_XI pin should be held either low or high, RTC_XO should be left
unconnected, RTC_CVDD should be connected to the device CVDD and RTC_VSS should remain
grounded.

5.32 General-Purpose Input/Output (GPIO)
The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs.
When configured as an output, a write to an internal register can control the state driven on the output pin.
When configured as an input, the state of the input is detectable by reading the state of an internal
register. In addition, the GPIO peripheral can produce CPU interrupts and EDMA events in different
interrupt/event generation modes. The GPIO peripheral provides generic connections to external devices.
The GPIO pins are grouped into banks of 16 pins per bank (i.e., bank 0 consists of GPIO [0:15]).
The device GPIO peripheral supports the following:
• Up to 144 Pins configurable as GPIO
• External Interrupt and DMA request Capability
– Every GPIO pin may be configured to generate an interrupt request on detection of rising and/or
falling edges on the pin.
– The interrupt requests within each bank are combined (logical or) to create eight unique bank level
interrupt requests.
– The bank level interrupt service routine may poll the INTSTATx register for its bank to determine
which pin(s) have triggered the interrupt.
– GPIO Banks 0, 1, 2, 3, 4, 5, 6, 7 and 8 Interrupts assigned to ARM INTC Interrupt Requests 42, 43,
44, 45, 46, 47, 48, 49 and 50 respectively
– GPIO Banks 0, 1, 2, 3, 4, 5, 6, 7 and 8 Interrupts assigned to DSP Events 65, 41, 49, 52, 54, 59,
62, 72 and 75 respectively
– GPIO Banks 0, 1, 2, 3, 4, and 5 are assigned to EDMA events 6, 7, 22, 23, 28, 29, and 29
respectively on Channel Controller 0 and GPIO Banks 6, 7, and 8 are assigned to EDMA events
16, 17, and 18 respectively on Channel Controller 1.
• Set/clear functionality: Firmware writes 1 to corresponding bit position(s) to set or to clear GPIO
signal(s). This allows multiple firmware processes to toggle GPIO output signals without critical section
protection (disable interrupts, program GPIO, re-enable interrupts, to prevent context switching to
anther process during GPIO programming).
• Separate Input/Output registers
• Output register in addition to set/clear so that, if preferred by firmware, some GPIO output signals can
be toggled by direct write to the output register(s).
• Output register, when read, reflects output drive status. This, in addition to the input register reflecting
pin status and open-drain I/O cell, allows wired logic be implemented.
The memory map for the GPIO registers is shown in Table 5-136.

5.33 Programmable Real-Time Unit Subsystem (PRUSS)
The Programmable Real-Time Unit Subsystem (PRUSS) consists of
• Two Programmable Real-Time Units (PRU0 and PRU1) and their associated memories
• An Interrupt Controller (INTC) for handling system interrupt events. The INTC also supports posting
events back to the device level host CPU.
• A Switched Central Resource (SCR) for connecting the various internal and external masters to the
resources inside the PRUSS.
The two PRUs can operate completely independently or in coordination with each other. The PRUs can
also work in coordination with the device level host CPU. This is determined by the nature of the program
which is loaded into the PRUs instruction memory. Several different signaling mechanisms are available
between the two PRUs and the device level host CPU.
The PRUs are optimized for performing embedded tasks that require manipulation of packed memory
mapped data structures, handling of system events that have tight realtime constraints and interfacing with
systems external to the device.
The PRUSS comprises various distinct addressable regions. Externally the subsystem presents a single
64Kbyte range of addresses. The internal interconnect bus (also called switched central resource, or SCR)
of the PRUSS decodes accesses for each of the individual regions. The PRUSS memory map is
documented in Table 5-140 and in Table 5-141. Note that these two memory maps are implemented
inside the PRUSS and are local to the components of the PRUSS.

Note that PRU0 accesses Data RAM0 at address 0x0000 0000, also PRU1 accesses Data RAM1 at address 0x0000 0000. Data RAM0
is intended to be the primary data memory for PRU0 and Data RAM1 is intended to be the primary data memory for PRU1. However for
passing information between PRUs, each PRU can access the data ram of the ‘other’ PRU through address 0x0000 2000.
The global view of the PRUSS internal memories and control ports is documented in Table 5-142. The
offset addresses of each region are implemented inside the PRUSS but the global device memory
mapping places the PRUSS slave port in the address range 0x01C3 0000-0x01C3 FFFF. The PRU0 and
PRU1 can use either the local or global addresses to access their internal memories, but using the local
addresses will provide access time several cycles faster than using the global addresses. This is because
when accessing via the global address the access needs to be routed through the switch fabric outside
PRUSS and back in through the PRUSS slave port.

5.34.1 JTAG Port Description
The device target debug interface uses the five standard IEEE 1149.1(JTAG) signals (TRST, TCK, TMS,
TDI, and TDO), a return clock (RTCK) due to the clocking requirements of the ARM926EJ-S and
emulation signals EMU0 and EMU1.
TRST holds the debug and boundary scan logic in reset (normal DSP operation) when pulled low (its
default state). Since TRST has an internal pull-down resistor, this ensures that at power up the device
functions in its normal (non-test) operation mode if TRST is not connected. Otherwise, TRST should be
driven inactive by the emulator or boundary scan controller. Boundary scan test cannot be performed
while the TRST pin is pulled low.

5.34.3 Initial Scan Chain Configuration
The first level of debug interface that sees the scan controller is the TAP router module. The debugger
can configure the TAP router for serially linking up to 16 TAP controllers or individually scanning one of
the TAP controllers without disrupting the IR state of the other TAPs.
5.34.3.1 Adding TAPS to the Scan Chain
The TAP router must be programmed to add additional TAPs to the scan chain. The following JTAG scans
must be completed to add the ARM926EJ-S to the scan chain.
A Power-On Reset (POR) or the JTAG Test-Logic Reset state configures the TAP router to contain only
the router’s TAP.

5.34.4 IEEE 1149.1 JTAG
The JTAG (1) interface is used for BSDL testing and emulation of the device.
The device requires that both TRST and RESET be asserted upon power up to be properly initialized.
While RESET initializes the device, TRST initializes the device's emulation logic. Both resets are required
for proper operation.
While both TRST and RESET need to be asserted upon power up, only RESET needs to be released for
the device to boot properly. TRST may be asserted indefinitely for normal operation, keeping the JTAG
port interface and device's emulation logic in the reset state.
TRST only needs to be released when it is necessary to use a JTAG controller to debug the device or
exercise the device's boundary scan functionality. Note: TRST is synchronous and must be clocked by
TCK; otherwise, the boundary scan logic may not respond as expected after TRST is asserted.
RESET must be released only in order for boundary-scan JTAG to read the variant field of IDCODE
correctly. Other boundary-scan instructions work correctly independent of current state of RESET.
For maximum reliability, the device includes an internal pulldown (IPD) on the TRST pin to ensure that
TRST will always be asserted upon power up and the device's internal emulation logic will always be
properly initialized.
JTAG controllers from Texas Instruments actively drive TRST high. However, some third-party JTAG
controllers may not drive TRST high but expect the use of a pullup resistor on TRST.
When using this type of JTAG controller, assert TRST to initialize the device after powerup and externally
drive TRST high before attempting any emulation or boundary scan operations.

To use boundary scan, the following sequence should be followed:
• Execute a valid reset sequence and exit reset
• Wait at least 6000 OSCIN clock cycles
• Enter boundary scan mode using the JTAG pins
No specific value is required on the EMU0 and EMU1 pins for boundary scan testing. If TRST is not driven
by the boundary scan tool or tester, TRST should be externally pulled high during boundary scan testing.

Device Support
Development Support
TI offers an extensive line of development tools for the device platform, including tools to evaluate the
performance of the processors, generate code, develop algorithm implementations, and fully integrate and
debug software and hardware modules. The tool's support documentation is electronically available within
the Code Composer Studio™ Integrated Development Environment (IDE).
The following products support development of the device applications:
Software Development Tools:
Code Composer Studio™ Integrated Development Environment (IDE): including Editor
C/C++/Assembly Code Generation, and Debug plus additional development tools
Scalable, Real-Time Foundation Software (DSP/BIOS™), which provides the basic run-time target
software needed to support any application.
Hardware Development Tools:
Extended Development System (XDS™) Emulator
For a complete listing of development-support tools for the device, visit the Texas Instruments web site
on the Worldwide Web at www.ti.com uniform resource locator (URL). For information on pricing and
availability, contact the nearest TI field sales office or authorized distributor.
6.1.2
Device and Development-Support Tool Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
DSP devices and support tools. Each DSP commercial family member has one of three prefixes: X, P or
NULL (e.g., SMOMAPL138B) Texas Instruments recommends two of three possible prefix designators for
its support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development
from engineering prototypes (TMX/TMDX) through fully qualified production devices/tools (TMS/TMDS).
Device development evolutionary flow:
X
Experimental device that is not necessarily representative of the final device's electrical
specifications.
P
Final silicon die that conforms to the device's electrical specifications but has not completed
quality and reliability verification.
NULL
Fully-qualified production device.
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully qualified development-support product.
X and P devices and TMDX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
Null devices and TMDS development-support tools have been characterized fully, and the quality and
reliability of the device have been demonstrated fully. TI's standard warranty applies.

SLVSAQ9 – JANUARY 2011
Predictions show that prototype devices (X or P) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system
because their expected end-use failure rate still is undefined. Only qualified production devices are to be
used.
TI device nomenclature also includes a suffix with the device family name. This suffix indicates the
package type (for example, GWT), the temperature range (for example, "Blank" is the commercial
temperature range), and the device speed range in megahertz (for example, "Blank" is the default).
Figure 6-1 provides a legend for reading the complete device.
