Note: The AE and NMIF bits can only be written with 0 after being read as 1, to clear the flags.
DMAOR is a 32-bit readable/writable register that specifies the DMAC transfer mode.
DMAOR is initialized to H'00000000 by a power-on or manual reset. They retain their values in
standby mode and deep sleep mode.
Bits 31 to 16—Reserved: These bits are always read as 0, and should only be written with 0.
Bit 15—On-Demand Data Transfer (DDT): Specifies on-demand data transfer mode.
Bit 15: DDT
