DMA Source/Destination Address Modification

Figure 3-21. On-Chip DMA Memory Map for Data and IO Space (DLAXS = 0 and SLAXS = 0)
Each DMA channel can be independently assigned high- or low-priority relative to each other. Multiple
DMA channels that are assigned to the same priority level are handled in a round-robin manner.
The DMA provides flexible address-indexing modes for easy implementation of data management
schemes such as autobuffering and circular buffers. Source and destination addresses can be indexed
separately and can be post-incremented, post-decremented, or post-incremented with a specified index
offset.
