12-channel DMA Controller

The DMA module contains 12 separate DMA channels.

Ten of these may be used for peripheral-to-memory or

memory-to-peripheral access. Two of these are

dedicated to memory-to-memory transfers. Each DMA

channel is connected to the 16-bit DMA request bus.

The request bus is a collection of requests, Serial Audio

and UARTs. Each DMA channel can be used

independently or dedicated to any request signal. For

each DMA channel, source and destination addressing

can be independently programmed to increment,

decrement, or stay at the same value. All DMA

addresses are physical, not virtual addresses.

Internal Boot ROM

The Internal 16 Kbyte ROM allows booting from FLASH

memory, SPI or UART. Consult the EP93xx User’s Guide

for operational details.
