Serial Interface Operation
Selecting and Changing the Operating Mode:
Table 27 lists the serial interface’s operating modes. To
select an operating mode, use one of these combinations of port mode register A (PMRA: $004) and the
serial mode register (SMR: $005) settings; to change the operating mode, always initialize the serial
interface internally by writing data to the serial mode register. Note that the serial interface is initialized by
writing data to the serial mode register. Refer to the following Serial Mode Register section for details.
