One to 256 bytes of data are transferred by one activation. The number of transfer times can be 1 to 256. When
the data transfer causing the DTCCTj (j = 0 to 23) register value to change to 0 is performed, an interrupt
request for the CPU is generated during DTC operation.
Table 15.6 shows Register Functions in Normal Mode.
