7.4.2
I/O mode can be selected independently for each channel.
One byte or word is transferred at each transfer request in I/O mode. A designated number of these
transfers are executed. One address is specified in the memory address register (MAR), the other
in the I/O address register (IOAR). The direction of transfer is determined automatically from the
activation source. The transfer is from the address specified in IOAR to the address specified in
MAR if activated by an SCI channel 0 receive-data-full interrupt or an A/D converter conversion
end interrupt, and from the address specified in MAR to the address specified in IOAR otherwise.
Table 7.6 indicates the register functions in I/O mode.

Register
Legend:
MAR:
IOAR: I/O address register
ETCR: Execute transfer count register
MAR and IOAR specify the source and destination addresses. MAR specifies a 24-bit source or
destination address, which is incremented or decremented as each byte or word is transferred.
