analog module is enabled all associated digital output ports are disabled and all associated digital input
ports read “1”.
3.4.4
If the port is used as an output the Reduced Drive Register allows the configuration of the drive strength.
3.4.5
The Pull Device Enable Register turns on a pull-up or pull-down device. The pull device becomes active
only if the pin is used as an input or as a wired-or output.
