Port P general purpose input/output data—Data Register, PWM input/output, pin interrupt input/output
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 buffered
pin input state is read.

Port P general purpose input/output data—Data Register, PWM output, routed TIM output, routed SCI1 TXD
output, pin interrupt input/output
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 buffered
pin input state is read.
