Serial Interface Operation
Selecting and Changing the Operating Mode:
Table 24 lists the serial interfaces’ operating modes. To
select an operating mode, use one of these combinations of port mode register A (PMRA: $004), and serial
mode register 1A (SM1A: $005) settings; to change the operating mode of serial interface 1, always
initialize the serial interface internally by writing data to serial mode register 1A. Note that serial interface
1 is initialized by writing data to serial mode register 1A. Refer to the following section Registers for
Serial Interface for details.
