3.3V operation and push-pull output.
A pull-up is switched on/off by changing the value of the P5UP register.
I/O direction is determined by the value of the P5DIR register.
PORT 5 Description
P5DIR.X : 1 = Input (Default) / 0 = Output
P5PUP.X : 0 = Pull-up resistor OFF, 1 = Pull-up resistor ON (Default)
