Description
Reserved
These bits are always read as 0. The write value
should always be 0.
DMA Mode Select 1 and 0
These bits select the transfer mode. Set these bits
when DMAOR.DME = 0.
Reserved
These bits are always read as 0.The write value
should always be 0.
Priority Mode 1 and 0
These bits determine the order of priority for
channel execution when transfer requests are
made for multiple channels simultaneously.
