Figure 32-7. 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
