— TMS320DM357 DMSoC 64-Bit Timer User's Guide. Describes the operation of the
software-programmable 64-bit timer in the TMS320DM357 Digital Media System-on-Chip (DMSoC).
Timer 0 and Timer 1 are used as general-purpose (GP) timers and can be programmed in 64-bit
mode, dual 32-bit unchained mode, or dual 32-bit chained mode; Timer 2 is used only as a
watchdog timer. The GP timer modes can be used to generate periodic interrupts or enhanced
direct memory access (EDMA) synchronization events. The watchdog timer mode is used to
provide a recovery mechanism for the device in the event of a fault condition, such as a non-exiting
code loop.
— TMS320DM357 DMSoC Serial Peripheral Interface (SPI) User's Guide. Describes the
serial peripheral interface (SPI) in the TMS320DM357 Digital Media System-on-Chip (DMSoC). The
SPI is a high-speed synchronous serial input/output port that allows a serial bit stream of
programmed length (1 to 16 bits) to be shifted into and out of the device at a programmed
bit-transfer rate. The SPI is normally used for communication between the DMSoC and external
peripherals. Typical applications include an interface to external I/O or peripheral expansion via
devices such as shift registers, display drivers, SPI EPROMs and analog-to-digital converters.
— TMS320DM357 DMSoC Host Port Interface (HPI) Reference Guide. This document
describes the host port interface in the TMS320DM357 Digital Media System-on-Chip (DMSoC).
The HPI provides a parallel port interface through which an external host processor can directly
access the TMS320DM357 DMSoC processor's resources (configuration and program/data
memories).
— TMS320DM357 DMSoC General-Purpose Input/Output (GPIO) User's Guide. Describes
the general-purpose input/output (GPIO) peripheral in the TMS320DM357 Digital Media
System-on-Chip (DMSoC). The GPIO peripheral provides dedicated general-purpose pins that can
be configured as either inputs or outputs. When configured as an input, you can detect the state of
the input by reading the state of an internal register. When configured as an output, you can write
to an internal register to control the state driven on the output pin.
— TMS320DM357 DMSoC Multimedia Card (MMC)/Secure Digital (SD) Card Controller
User's Guide. Describes the multimedia card (MMC)/secure digital (SD) card controller in the
TMS320DM357 Digital Media System-on-Chip (DMSoC). The MMC/SD card is used in a number of
applications to provide removable data storage. The MMC/SD controller provides an interface to
external MMC and SD cards. The communication between the MMC/SD controller and MMC/SD
card(s) is performed by the MMC/SD protocol.
— TMS320DM357 DMSoC Asynchronous External Memory Interface (EMIF) User's
Guide. Describes the asynchronous external memory interface (EMIF) in the TMS320DM357
Digital Media System-on-Chip (DMSoC). The EMIF supports a glueless interface to a variety of
external devices.
— TMS320DM357 DMSoC Enhanced Direct Memory Access (EDMA) Controller User's
Guide. Describes the operation of the enhanced direct memory access (EDMA3) controller in the
TMS320DM357 Digital Media System-on-Chip (DMSoC). The EDMA3 controller’s primary purpose
is to service user-programmed data transfers between two memory-mapped slave endpoints on the
DMSoC.
— TMS320DM357 DMSoC Audio Serial Port (ASP) User's Guide. Describes the operation
of the audio serial port (ASP) audio interface in the TMS320DM357 Digital Media System-on-Chip
(DMSoC). The primary audio modes that are supported by the ASP are the AC97 and IIS modes. In
addition to the primary audio modes, the ASP supports general serial port receive and transmit
operation, but is not intended to be used as a high-speed interface.
— TMS320DM357 DMSoC Ethernet Media Access Controller (EMAC)/Management Data
Input/Output (MDIO) Module User's Guide. Discusses the ethernet media access controller
(EMAC) and physical layer (PHY) device management data input/output (MDIO) module in the
TMS320DM357 Digital Media System-on-Chip (DMSoC). The EMAC controls the flow of packet
data from the DMSoC to the PHY. The MDIO module controls PHY configuration and status
monitoring.
