2.3.2 Register Descriptions
The following table summarizes the effect of the various conï¬guration bits, i.e. data direction (DDR),
output level (IO), reduced drive (RDR), pull enable (PE), pull select (PS) on the pin function and pull
device activity.
The conï¬guration bit PS is used for two purposes:
1. Conï¬gure 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.
