The INTCON registers are readable and writable
registers, which contain various enable, priority and
flag bits.

INTCON Registers
A mismatch condition will continue to set the RBIF bit. Reading PORTB will end the
mismatch condition and allow the bit to be cleared.
RB port change interrupts also require the individual pin IOCB enables.
GIE/GIEH: Global Interrupt Enable bit
When IPEN = 0:
1 = Enables all unmasked interrupts
0 = Disables all interrupts including peripherals
When IPEN = 1:
1 = Enables all high priority interrupts
0 = Disables all interrupts including low priority
PEIE/GIEL: Peripheral Interrupt Enable bit
When IPEN = 0:
1 = Enables all unmasked peripheral interrupts
0 = Disables all peripheral interrupts
When IPEN = 1:
1 = Enables all low priority interrupts
0 = Disables all low priority interrupts
TMR0IE: TMR0 Overflow Interrupt Enable bit
1 = Enables the TMR0 overflow interrupt
0 = Disables the TMR0 overflow interrupt
INT0IE: INT0 External Interrupt Enable bit
1 = Enables the INT0 external interrupt
0 = Disables the INT0 external interrupt
RBIE: Port B Interrupt-On-Change (IOCx) Interrupt Enable bit
1 = Enables the IOCx port change interrupt
0 = Disables the IOCx port change interrupt
TMR0IF: TMR0 Overflow Interrupt Flag bit
1 = TMR0 register has overflowed (must be cleared by software)
0 = TMR0 register did not overflow
INT0IF: INT0 External Interrupt Flag bit
1 = The INT0 external interrupt occurred (must be cleared by software)
0 = The INT0 external interrupt did not occur
RBIF: Port B Interrupt-On-Change (IOCx) Interrupt Flag bit
1 = At least one of the IOC<3:0> (RB<7:4>) pins changed state (must be cleared by software)
0 = None of the IOC<3:0> (RB<7:4>) pins have changed state

Interrupt flag bits are set when an interrupt
condition occurs, regardless of the state of
its corresponding enable bit or the global
enable bit. User software should ensure
the appropriate interrupt flag bits are clear
prior to enabling an interrupt. This feature
allows for software polling.
