7.5.2
In repeat mode, one activation source transfers one byte or one word of data. Table 7.3 lists the
register functions in repeat mode. From 1 to 256 transfers can be specified. Once the specified
number of transfers have completed, the initial states of the transfer counter and the address
register that is specified as the repeat area is restored, and transfer is repeated. In repeat mode, the
transfer counter value does not reach H'00, and therefore CPU interrupts cannot be requested when
the DISEL bit in MRB is cleared to 0.
