Descriptions
Reserved
These bits are always read as 0. The write value should
always be 0.
Priority Mode 1, 0
Determine the priority between channels when there
are transfer requests for multiple channels
simultaneously.
00: CH0 > CH1 > CH2 > CH3 > CH4 > CH5 (DMAOR0)
01: CH0 > CH2 > CH3 > CH1 > CH4 > CH5 (DMAOR0)
10: Setting prohibited
11: Round-robin mode for CH0 to CH5 (DMAOR0)
When round-robin mode is specified, do not mix the
cycle steal mode and the burst mode in any channels
(channels 0 to 5) corresponding to DMAOR0. For any
channels corresponding to DMAOR1 (channels 6 to
11), only normal mode 2 in the cycle steal mode
(CHCR.LCKN = 1, CHCR.TB = 0) can be specified.
Reserved
These bits are always read as 0. The write value should
always be 0.
