These bits specify an SAR operation after a data
transfer.
0×: SAR is fixed
10: SAR is incremented after a transfer
11: SAR is decremented after a transfer
Destination Address Mode 1 and 0
These bits specify a DAR operation after a data
transfer.
0×: DAR is fixed
10: DAR is incremented after a transfer
11: DAR is decremented after a transfer
DTC Mode 1 and 0
These bits specify the DTC transfer mode.
00: Normal mode
01: Repeat mode
