Serial I/O2
The serial I/O2 function can be used only for clock synchronous
serial I/O.
For clock synchronous serial I/O2, the transmitter and the receiver
must use the same clock. When the internal clock is used, transfer
is started by a write signal to the serial I/O2 register.
When an internal clock is selected as the synchronous clock of the
serial I/O2, either P62 or P63 can be selected as an output pin of
the synchronous clock. In this case, the pin that is not selected as
an output pin of the synchronous clock functions as a port.
[Serial I/O2 Control Register (SIO2CON)] 001D16
The serial I/O2 control register contains 8 bits which control vari-
ous serial I/O2 functions.
