• External request
Block Transfer Mode: In response to a single transfer request, a block transfer of the specified
block size is carried out. This is repeated the specified number of times, once each time there is a
transfer request. At the end of each single block transfer, one address is restored to its original
setting. An interrupt request can be sent to the CPU or DTC when the specified number of block
transfers have been completed. Both addresses are specified as 24 bits.
7.5.2
Sequential mode can be specified by clearing the RPE bit in DMACR to 0. In sequential mode,
MAR is updated after each byte or word transfer in response to a single transfer request, and this is
executed the number of times specified in ETCR.
One address is specified by MAR, and the other by IOAR. The transfer direction can be specified
by the DTDIR bit in DMACR.
Table 7.6 summarizes register functions in sequential mode.

In response to a single transfer request, the specified number of transfers are carried out, one
byte or one word at a time. An interrupt request can be sent to the CPU or DTC when the
specified number of transfers have been completed. Both addresses are specified as 24 bits.
