Port S general purpose input/output data—Data Register
Port S pin 3 is associated with the TXD signal of the SCI0 module.
When not used with the alternative function, this pin can be used as general purpose I/O.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the
buffered pin input state is read.
Port S general purpose input/output data—Data Register
Port S bits 2 is associated with the RXD signal of the SCI0 module.
When not used with the alternative function, this pin can be used as general purpose I/O.
If the associated data direction bit of this pin is set to 1, a read returns the value of the port register, otherwise the
buffered pin input state is read.
Port S input data—
This register always reads back the buffered state of the associated pins. This can also be used to detect overload
or short circuit conditions on output pins.
