PorT data register port S — General-purpose input/output data, SPI SS
When not used with the alternative function, the associated pin can be used as general-purpose I/O. In
general-purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the
synchronized pin input state is read.
PorT data register port S — General-purpose input/output data, SPI SCK
When not used with the alternative function, the associated pin can be used as general-purpose I/O. In
general-purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the
synchronized pin input state is read.
PorT data register port S — General-purpose input/output data, ECLK, SPI MOSI, routed SCI1, routed PWM,
routed ETRIG
When not used with the alternative function, the associated pin can be used as general-purpose I/O. In
general-purpose output mode the register bit value is driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the
synchronized pin input state is read.
