Section 14 Direct Memory Access Controller (DMAC)
14.2.6
Note: * Only a write of 0 after a read of 1 is enabled for the AE and NMIF bits.
The DMA operation register (DMAOR) is a 16-bit read/write register that controls the DMAC
transfer mode.
This register is initialized to 0 by a power-on reset. The previous values are held in standby mode.
Bits 15 to 10—Reserved: These bits are always read as 0 and should only be written with 0.
Bits 9 and 8—Priority Mode 1, 0 (PR1 and PR0): PR1 and PR0 select the priority level between
channels when transfer requests are generated for multiple channels simultaneously.
Bit 9: PR1

1
Bits 7 to 3—Reserved: These bits are always read as 0 and should only be written with 0.
