7.5.3
Idle mode can be specified by setting the RPE bit and DTIE bit in DMACR 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 7.7 summarizes register functions in idle mode.

IOAR:
ETCR: Execute transfer count register
DTDIR: Data transfer direction bit
MAR specifies the start address of the transfer source or transfer destination as 24 bits. MAR is
neither incremented nor decremented each time a byte or word is transferred.
IOAR specifies the lower 16 bits of the other address. The 8 bits above IOAR have a value of
H'FF.
