Reserved. These bits will be 0 when read.
Real Time Clock Interrupt Priority. This bit controls the priority of the real–
time clock interrupt on the DS87C530. This bit will read 0 on all other devices.
0 = The real-time clock interrupt is a low priority interrupt.
1 = The real-time clock interrupt is a high priority interrupt.
Interrupt Priority. This bit controls the priority of the watchdog interrupt.
0 = The watchdog interrupt is a low priority interrupt.
1 = The watchdog interrupt is a high priority interrupt.
External Interrupt 5 Priority. This bit controls the priority of external interrupt
5.
0 = External interrupt 5 is a low priority interrupt.
1 = External interrupt 5 is a high priority interrupt.
External Interrupt 4 Priority. This bit controls the priority of external interrupt
4.
0 = External interrupt 4 is a low priority interrupt.
1 = External interrupt 4 is a high priority interrupt.
External Interrupt 3 Priority. This bit controls the priority of external interrupt
3.
0 = External interrupt 3 is a low priority interrupt.
1 = External interrupt 3 is a high priority interrupt.
External Interrupt 2 Priority. This bit controls the priority of external interrupt
2.
0 = External interrupt 2 is a low priority interrupt.
1 = External interrupt 2 is a high priority interrupt.
