DMA Controller Module
14.1
This chapter describes the Direct Memory Access (DMA) controller module. It provides an
overview of the module and describes in detail its signals and registers. The latter sections of this
chapter describe operations, features, and supported data transfer modes in detail.
14.1.1 Overview
The DMA controller module provides an efficient way to move blocks of data with minimal
processor interaction. The DMA module, shown in
byte, word, longword, or 16-byte burst data transfers. Each channel has a dedicated source address
register (SARn), destination address register (DARn), byte count register (BCRn), control register
(DCRn), and status register (DSRn). Transfers are dual address to on-chip devices, such as UART
and SDRAM controller.

Introduction
The designation “n” is used throughout this section to refer to registers
or signals associated with one of the four identical DMA channels:
DMA0, DMA1, DMA2 or DMA3.
