Reset:
• DIS[3:0]
Write one to this field to disable the relevant DMAC Channel. The content of the FIFO is lost and the current AHB access is
terminated. Software must poll DIS[3:0] field in the DMAC_CHSR register to be sure that the channel is disabled.
• RES[3:0]
Write one to this field to resume the channel transfer restoring its context.
