3.4.6
The Polarity Select Register selects either a pull-up or pull-down device if enabled. The pull device
becomes active only if the pin is used as an input or as a wired-or output.
3.4.7
The following table summarizes the effect of various configuration in the Data Direction (DDR),
Input/Output (I/O), reduced drive (RDR), Pull Enable (PE), Pull Select (PS) and Interrupt Enable (IE)
register bits. The PS configuration bit is used for two purposes:

Applicable only on Port AD.
Digital outputs are disabled and digital input logic is forced to “1” when an analog module associated with the port is enabled.
