Section 8 Data Transfer Controller
8.3.6
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 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.
Table 8.7 lists the register information in repeat mode and figure 8.7 shows the memory map in
repeat mode.
