PS
IP.4
Defines Serial Port interrupt priority level
PT1
IP.3
Defines Timer 1 interrupt priority level
PX1
IP.2
Defines External Interrupt 1 priority level
PT0
IP.1
Defines Timer 0 interrupt priority level
PX0
IP.0
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 interrupted 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.

Register Description:
TF1
TCON.7
Timer 1 overflow flag. Set by hardware
when the Timer/Counter 1 overflows.
Cleared by hardware as processor
vectors to the interrupt service routine.
TR1
TCON.6
Timer 1 run control bit. Set/Cleared by
software to turn Timer/Counter 1 ON/
OFF.
TF0
TCON.5
Timer 0 overflow flag. Set by hardware
when the Timer/Counter 0 overflows.
Cleared by hardware as processor
vectors to the interrupt service routine.
TR0
TCON.4
Timer 0 run control bit. Set/Cleared by
software to turn Timer/Counter 0 ON/
OFF.
IE1
TCON.3
External Interrupt 1 edge flag. Set by
hardware when the External Interrupt
edge is detected. Cleared by hardware
when interrupt is processed.
IT1
TCON.2
Interrupt 1 type control bit. Set/Cleared
by software specify falling edge/low
level triggered External Interrupt.
IE0
TCON.1
External Interrupt 0 edge flag. Set by
hardware when the External Interrupt
edge is detected. Cleared by hardware
when interrupt is processed.
IT0
TCON.0
Interrupt 0 type control bit. Set/Cleared
by software specify falling edge/low
level triggered External Interrupt.
