Chapter 16
DMA Controller Module
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.
16.1
The DMA controller module provides an efficient way to move blocks of data with minimal processor
interaction. The DMA module, shown in
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, SDRAM controller, and
GPIOs.

Overview
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.
