As in I/O mode, MAR and IOAR specify the source and destination addresses. MAR specifies a
24-bit source or destination address. IOAR specifies the lower 8 bits of a fixed address. The upper
16 bits are all 1s. IOAR is not incremented or decremented.
Figure 8.6 illustrates how repeat mode operates.
The transfer count is specified as an 8-bit value in ETCRH and ETCRL. The maximum transfer
count is 255, obtained by setting both ETCRH and ETCRL to H'FF.
Transfers can be requested (activated) by compare match/input capture A interrupts from ITU
channels 0 to 3, transmit-data-empty and receive-data-full interrupts from SCI channel 0, and
external request signals.
For the detailed settings see section 8.2.4, Data Transfer Control Registers (DTCR).
