One to 255 bytes of data are transferred by one activation. Either of the transfer source or destination should be
specified as the repeat area. The number of transfer times can be 1 to 255. On completion of the specified
number of transfer times, the DTCCTj (i =0 to 23) register and the address specified for the repeat area are
initialized to continue transfers. When the data transfer causing the DTCCTj register value to change to 0 is
performed while the RPTINT bit in the DTCCRj register is 1 (interrupt generation enabled), an interrupt request
for the CPU is generated during DTC operation.
The lower 8 bits of the initial value for the repeat area address must be 00h. The size of data to be transferred
must be set to 255 bytes or less before the specified number of transfer times is completed.
Table 15.7 shows Register Functions in Repeat Mode.
