This bit is un-implemented and will read high.
This bit defines the Serial port 1 interrupt priority. PS = 1 sets it to higher priority level.
This bit defines the Timer 2 interrupt priority. PT2 = 1 sets it to higher priority level.
This bit defines the Serial port 0 interrupt priority. PS = 1 sets it to higher priority level.
This bit defines the Timer 1 interrupt priority. PT1 = 1 sets it to higher priority level.
This bit defines the External interrupt 1 priority. PX1 = 1 sets it to higher priority level.
This bit defines the Timer 0 interrupt priority. PT0 = 1 sets it to higher priority level.
This bit defines the External interrupt 0 priority. PX0 = 1 sets it to higher priority level.
