About This Manual

This document provides a functional description of the Ethernet Media Access Controller (EMAC) and physical layer (PHY) device Management Data Input/Output (MDIO) module integrated in the TMS320DM36x Digital Media System-on-Chip (DMSoC). Included are the features of the EMAC and MDIO modules, a discussion of their architecture and operation, how these modules connect to the outside world, and the registers description for each module.

Notational Conventions

This document uses the following conventions.

•Hexadecimal numbers are shown with the suffix h. For example, the following number is 40 hexadecimal (decimal 64): 40h.

•Registers in this document are shown in figures and described in tables.

–Each register figure shows a rectangle divided into fields that represent the fields of the register. Each field is labeled with its bit name, its beginning and ending bit numbers above, and its read/write properties below. A legend explains the notation used for the properties.

–Reserved bits in a register figure designate a bit that is used for future device expansion.

SPRUFG5 — TMS320DM365 Digital Media System-on-Chip (DMSoC) ARM Subsystem Reference

Guide This document describes the ARM Subsystem in the TMS320DM36x Digital Media System-on-Chip (DMSoC). The ARM subsystem is designed to give the ARM926EJ-S (ARM9) master control of the device. In general, the ARM is responsible for configuration and control of the device; including the components of the ARM Subsystem, the peripherals, and the external memories.

SPRUFH1 — TMS320DM36x Digital Media System-on-Chip (DMSoC) Serial Peripheral Interface (SPI) Users Guide This document describes the serial peripheral interface (SPI) in the TMS320DM36x 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.
