This section describes the major functional blocks of the DMA Controller.
The DMA Controller enables peripheral-to-memory, memory-to-peripheral,
peripheral-to-peripheral, and memory-to-memory transactions. Each DMA stream
provides unidirectional serial DMA transfers for a single source and destination. For
example, a bidirectional port requires one stream for transmit and one for receive. The
source and destination areas can each be either a memory region or a peripheral, and
can be accessed through the AHB master.
Controller.
The functions of the DMA Controller are described in the following sections.
All transactions to DMA Controller registers on the AHB slave interface are 32 bits wide.
8-bit and 16-bit accesses are not supported and will result in an exception.
•
•
•
•
Big-endian and little-endian support. The DMA Controller defaults to little-endian
mode on reset.
An interrupt to the processor can be generated on a DMA completion or when a DMA
error has occurred.
Raw interrupt status. The DMA error and DMA count raw interrupt status can be read
prior to masking.
DMA can operate in Sleep mode. (Note that in Sleep mode the GPDMA cannot
access the flash memory).
