3.3.3.5
Read: Anytime. Write: Anytime.
This register configures whether a pull-up or a pull-down device is activated on configured input pins. If
a pin is configured as output, the corresponding Pull Device Enable Register bit has no effect.
3.3.3.6
Read: Anytime. Write: Anytime.
The Port P Polarity Select Register selects whether a pull-down or a pull-up device is connected to the pin.
The Port P Polarity Select Register is effective only when the corresponding Data Direction Register bit
is set to 0 (input) and the corresponding Pull Device Enable Register bit is set to 1.
