PS1 Serial Port 1 Interrupt. This bit controls the priority of the serial Port 1 interrupt.

bit 6 0 = Serial Port 1 priority is determined by the natural priority order.

1 = Serial Port 1 is a high priority interrupt.

PT2 Timer 2 Interrupt. This bit controls the priority of the Timer 2 interrupt.

bit 5 0 = Timer 2 priority is determined by the natural priority order.

1 = Timer 2 priority is a high priority interrupt.

PS0 Serial Port 0 Interrupt. This bit controls the priority of the serial Port 0 interrupt.

bit 4 0 = Serial Port 0 priority is determined by the natural priority order.

1 = Serial Port 0 is a high priority interrupt.

PT1 Timer 1 Interrupt. This bit controls the priority of the Timer 1 interrupt.

bit 3 0 = Timer 1 priority is determined by the natural priority order.

1 = Timer 1 priority is a high priority interrupt.

PX1 External Interrupt 1. This bit controls the priority of external interrupt 1.

bit 2 0 = External interrupt 1 priority is determined by the natural priority order.

1 = External interrupt 1 is a high priority interrupt.

PT0 Timer 0 Interrupt. This bit controls the priority of the Timer 0 interrupt.

bit 1 0 = Timer 0 priority is determined by the natural priority order.

1 = Timer 0 priority is a high priority interrupt.

PX0 External Interrupt 0. This bit controls the priority of external interrupt 0.

bit 0 0 = External interrupt 0 priority is determined by the natural priority order.

1 = External interrupt 0 is a high priority interrupt.
