21.4.1 Memory regions accessible by the micro DMA controller
The DMA controller supports data transfer sizes of 8, 16, or 32 bit (byte, half-word, or
word), configured through the channel control data structure (see
data transfer size and the destination data transfer size must be the same.
The controller always uses 32-bit data transfers when it accesses a channel control data
structure.
The DMA control block contains the control logic that performs the following tasks:
Remark: Peripheral-to-peripheral transactions are not supported because each channel
only provides a single DMA request interface.
The DMA channel control data structure is written to and updated in SRAM.
Memory-to-memory DMA transfers are supported as software-controlled transfers.

Arbitrates the incoming requests.
Indicates which channel is active.
Indicates when a channel is complete.
Indicates when an error has occurred on the AHB-Lite interface.
Enables slow peripherals to stall the completion of a DMA cycle.
Waits for a request to clear before completing a DMA cycle.
Performs multiple or single DMA transfers for each request.
Performs the following types of DMA transfers:
– memory-to-memory
– memory-to-peripheral
– peripheral-to-memory
