A logical channel can be configured in its DMA4_CSDPi[17:16] bits to use one of three write access handshake modes for the destination:
- Nonposted write: Each write must complete before transfer can continue or complete.
- Posted write: Transfer continues without waiting for each write to complete (may improve performance with slow devices).
- Posted with final write nonposted: Transfer continues without waiting for each write to complete, but final write completes before transfer can complete.
