Chapter 3 Port Integration Module (PIM9E256V1)
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:
1
2
160
DDR
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.

1. Configure the sensitive interrupt edge (rising or falling), if interrupt is enabled.
2. Select either a pull-up or pull-down device if PE is set to “1”.
