Repeat mode can be specified by setting the RPE bit in DMACR to 1, and clearing the DTIE bit in
DMABCRL to 0. In repeat mode, MAR is updated after each byte or word transfer in response to
a single transfer request, and this is executed the number of times specified in ETCRL. On
completion of the specified number of transfers, MAR and ETCRL are automatically restored to
their original settings and operation continues. 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 repeat mode.
Table 7.7
MAR specifies the start address of the transfer source or transfer destination as 24 bits. MAR is
incremented or decremented by 1 or 2 each time a byte or word is transferred. IOAR specifies the
lower 16 bits of the other address. The upper 8 bits of IOAR have a value of H'FF. The number of
transfers is specified as 8 bits by ETCRH and ETCRL. The maximum number of transfers, when
H'00 is set in both ETCRH and ETCRL, is 256.
