Figure 24-5. Multi-buffer with Linked List Address for Source and Destination
If the user needs to execute a DMAC transfer where the source and destination address are
contiguous but the amount of data to be transferred is greater than the maximum buffer size
DMAC_CTRLAx.BTSIZE, then this can be achieved using the type of multi-buffer transfer as
shown in
