CANBIP
Bit 7 CAN 0/1 Activity Interrupt Priority. This bit controls the priority of the CAN 0/1
Activity Interrupt
0 = The CAN 0/1 Activity Interrupt is a low priority interrupt.
1 = The CAN 0/1 Activity Interrupt is a high priority interrupt.
C0IP
Bit 6 CAN 0 Interrupt Priority. This bit controls the priority of the CAN 0 Interrupt
0 = The CAN 0 Interrupt is a low priority interrupt.
1 = The CAN 0 Interrupt is a high priority interrupt.
C1IP
Bit 5 CAN 1 Interrupt Priority. This bit controls the priority of the CAN 1 Interrupt
0 = The CAN 1 Interrupt is a low priority interrupt.
1 = The CAN 1 Interrupt is a high priority interrupt.
PWDI
Bit 4 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.
PX5
Bit 3 External Interrupt 5 Priority. This bit controls the priority of external interrupt 5.
0 = External interrupt 5 is a low priority interrupt.
