9.5.2
In repeat mode, one operation transfers one byte or one word of data. Table 9.5 lists the register
function in repeat mode. From 1 to 256 transfers can be specified. Once the specified number of
transfers has 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.
