Destination Scatter 0 (DSR0) – Offset 850
The Destination Scatter register contains two fields:
Destination scatter count field (DSRx.DSC) . Specifies the number of contiguous destination transfers of CTLx.DST_TR_WIDTH between successive scatter boundaries.
Destination scatter interval field (DSRx.DSI) . Specifies the destination address increment/decrement in multiples of CTLx.DST_TR_WIDTH on a scatter boundary when scatter mode is enabled for the destination transfer. The CTLx.DINC field controls whether the address increments or decrements. When the CTLx.DINC field indicates a fixed address control, then the address remains constant throughout the transfer and the DSRx register is ignored.
