Chapter 10
DMA Controller
The MCF5272 has a one-channel DMA controller that supports memory-to-memory DMA transfers that
can be used for block data moves. This chapter describes in detail its signals, registers, and operating
modes.
10.1
A source and destination address must be specified for any dual-address DMA transfer. These addresses
can have different data transfer types, but there is always a read from the source address followed by a
write to the destination address. On the MCF5272, sources and destinations can be SDRAM, external
SRAM, or on-chip peripheral in any combination.
Note that transfers to on-chip peripherals are limited by the transfer type supported by a specific peripheral.

DMA Data Transfer Types
Memory-to-memory DMA transfers run to completion if the assume request
bit in the system configuration register, SCR[AR], is set. This generally
prevents the CPU from recognizing interrupts and blocks bus accesses by
other on-chip bus masters. It is best not to enable SCR[AR] when the DMA
controller is in use. When AR = 0, the DMA controller allows the CPU and
Ethernet controller to obtain bus access.
