Defines Timer 2 interrupt priority level
Defines Serial Port interrupt priority level
Defines Timer 1 interrupt priority level
Defines External Interrupt 1 priority level
Defines Timer 0 interrupt priority level
Defines External Interrupt 0 priority level
Notes:
1. In order to assign higher priority to an interrupt the
coresponding bit in the IP register must be set to 1. While
an interrupt service is in progress, it cannot be inter-
rupted by a lower or same level interrupt.
2. Priority within level is only to resolve simultaneous
requests of the same priority level. From high-to-low,
interrupt sources are listed below:
IE0
TF0
IE1
TF1
RI or TI
TF2 or EXF2
3.
User software should not write 1s to reserved bits. These
bits may be used in future products to invoke new features.

Timer 1 overflow flag. Set by hardware
when the Timer/Counter 1 overflows.
Cleared by hardware as processor
vectors to the interrupt service routine.
Timer 1 run control bit. Set/Cleared by
software to turn Timer/Counter 1 ON/
OFF.
Timer 0 overflow flag. Set by hardware
when the Timer/Counter 0 overflows.
Cleared by hardware as processor
vectors to the interrupt service routine.
Timer 0 run control bit. Set/Cleared by
software to turn Timer/Counter 0 ON/
OFF.
External Interrupt 1 edge flag. Set by
hardware when the External Interrupt
edge is detected. Cleared by hardware
when interrupt is processed.
Interrupt 1 type control bit. Set/Cleared
by software specify falling edge/low level
triggered External Interrupt.
External Interrupt 0 edge flag. Set by
hardware when the External Interrupt
edge is detected. Cleared by hardware
when interrupt is processed.
Interrupt 0 type control bit. Set/Cleared
by software specify falling edge/low level
triggered External Interrupt.
