Repeat Mode: Performs the transfer of one byte, one word, or one longword for each activation.
Either the transfer source or transfer destination is designated as the repeat area. Table 8.3 lists the
register information in repeat mode.
From 1 to 256 transfers can be specified. Once the specified number of transfers have ended, the
initial state of the transfer counter and the address register 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 DISEL = 0.
