Port S general purpose input/output data—Data Register
Port S pin 7 is associated with the SS signal of the SPI0 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 pin 6 is associated with the SCK signal of the SPI0 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 pin 5 is associated with the MOSI signal of the SPI0 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 pin 4 is associated with the MISO signal of the SPI0 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 pin 3 is associated with the TXD signal of the SCI1 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 SCI1 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.
