level (IO), reduced drive (RDR), pull enable (PE), pull select (PS), and interrupt enable (IE) for the
ports.
The configuration bit PS is used for two purposes:
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 active.
