Serial Interface Operation
Selecting and Changing the Operating Mode:
Table 28 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 serial
mode register A (SMRA: $005) settings; to change the operating mode, always initialize the serial interface
internally by writing data to serial mode register A. Note that the serial interface is initialized by writing
data to serial mode register A. Refer to the following Serial Mode Register A section for details.
