Section 7 DMA Controller (DMAC)
7.5.3
Idle mode can be specified by setting the RPE bit in DMACR and DTIE bit in DMABCRL to 1. In
idle mode, one byte or word is transferred in response to a single transfer request, and this is
executed the number of times specified in ETCR. One address is specified by MAR, and the other
by IOAR. The transfer direction can be specified by the DTDIR bit in DMACR. Table 7.6
summarizes register functions in idle mode.
