Bit 7 Reserved. Read data is indeterminate.
PS1
Bit 6 Serial Port 1 Interrupt. This bit controls the priority of the serial port 1
interrupt.
0 = Serial port 1 priority is determined by the natural priority order.
1 = Serial port 1 is a high priority interrupt.
PT2
Bit 5 Timer 2 Interrupt. This bit controls the priority of Timer 2 interrupt.
0 = Timer 2 is determined by the natural priority order.
1 = Timer 2 is a high priority interrupt.
PS0
Bit 4 Serial Port 0 Interrupt. This bit controls the priority of the serial port 0
interrupt.
0 = Serial port 0 priority is determined by the natural priority order.
1 = Serial port 0 is a high priority interrupt.
PT1
Bit 3 Timer 1 Interrupt. This bit controls the priority of Timer 1 interrupt.
0 = Timer 1 is determined by the natural priority order.
1 = Timer 1 is a high priority interrupt.
PX1
Bit 2 External Interrupt 1. This bit controls the priority of external interrupt 1.
0 = External interrupt 1 is determined by the natural priority order.
1 = External interrupt 1 is a high priority interrupt.
