2.2.2.3
The INTCON register is a readable and writable regis-
ter, which contains various enable and flag bits for the
TMR0 register overflow, RB port change and external
RB0/INT pin interrupts.

bit 7
GIE: Global Interrupt Enable bit
1 = Enables all unmasked interrupts
0 = Disables all interrupts
PEIE: Peripheral Interrupt Enable bit
1 = Enables all unmasked peripheral interrupts
0 = Disables all peripheral interrupts
TMR0IE: TMR0 Overflow Interrupt Enable bit
1 = Enables the TMR0 interrupt
0 = Disables the TMR0 interrupt
INTE: RB0/INT External Interrupt Enable bit
1 = Enables the RB0/INT external interrupt
0 = Disables the RB0/INT external interrupt
RBIE: RB Port Change Interrupt Enable bit
1 = Enables the RB port change interrupt
0 = Disables the RB port change interrupt
TMR0IF: TMR0 Overflow Interrupt Flag bit
1 = TMR0 register has overflowed (must be cleared in software)
0 = TMR0 register did not overflow
INTF: RB0/INT External Interrupt Flag bit
1 = The RB0/INT external interrupt occurred (must be cleared in software)
0 = The RB0/INT external interrupt did not occur
RBIF: RB Port Change Interrupt Flag bit
1 = At least one of the RB7:RB4 pins changed state; a mismatch condition will continue to set
0 = None of the RB7:RB4 pins have changed state

R = Readable bit

the bit. Reading PORTB will end the mismatch condition and allow the bit to be cleared
(must be cleared in software).

RBIE
Interrupt flag bits are set when an interrupt
condition occurs regardless of the state of its
corresponding enable bit or the global
enable bit, GIE (INTCON<7>). User software
should ensure the appropriate interrupt flag
bits are clear prior to enabling an interrupt.
