Section 9 Data Transfer Controller (DTC)
9.5.1
In normal mode, one operation transfers one byte or one word of data.
From 1 to 65,536 transfers can be specified. Once the specified number of transfers have been
completed, a CPU interrupt can be requested.
Table 9.3 lists the register information in normal mode. Figure 9.6 shows the memory mapping in
normal mode.

9.5.2
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.
