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
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.
