9.2.2 DMA Source and Destination Addressing
The source and destination for DMA transfers are dictated by the request select dedicated to the peripheral instance. The
DMACHn_CFG.reqsel. field dictates the source and destination for a channel’s DMA transfer as shown in Table 9-2. The
DMACHn_SRC and DMACHn_DST registers hold the source and/or destination memory addresses, depending on the
specific operation.
The DMACHn_CFG.srcinc field is ignored when the DMA source is a peripheral memory, and the DMACHn_CFG.dstinc field
is ignored when the DMA destination is a peripheral memory.
