7.3.6
In repeat mode, one operation transfers one byte or one word of data.
From 1 to 256 transfers can be specified. Once the specified number of transfers have ended, the
initial address register state specified by the transfer counter and repeat area resumes and transfer
is repeated. In repeat mode the transfer counter does not reach H'00, and therefore CPU interrupts
cannot be requested when DISEL = 0.
Table 7.6 lists the register information in repeat mode and figure 7.7 shows memory mapping in
repeat mode.
