11.2.5
The DMA operation register (DMAOR) is a 16-bit readable/writable register that controls the
DMAC transfer mode.
These register values are initialized to 0 in a reset. The previous value is retained in standby mode.
Note: * Only 0 can be written to the AE and NMIF bits after 1 is read.
Bits 15 to 10—Reserved: These bits are always read as 0. The write value should always be 0.
Bits 9 and 8—Priority Mode Bits 1 and 0 (PR1, PR0): Select the priority level between
channels when there are simultaneous transfer requests for multiple channels.
Bits 7 to 3—Reserved: These bits are always read as 0. The write value should always be 0.
