DLAi:

DAIi

Load address

0: DCAi content incremented after each data transfer (default)

1: DCAi content loaded with DIA content if DCCi value is 0, or DCAi content

incremented if DCCi value is not equal to 0

Address increment

0: DCAi content unchanged (default)

1: DCAi content modified according to DLAi state

DMS: Mask sensitivity control register

Two bits are dedicated to each DMA channel (bits 0 and 1 to channel 0, bits 4 and 5 to channel

1, bits 8 and 9 to channel 2, bits 12 and 13 to channel 3).
