2.2.2.3
The INTCON register is a readable and writable
register, which contains the various enable and flag bits
for TMR0 register overflow, PORTB change and
external RB0/INT/SEG0 pin interrupts.

INTCON Register
INTCON – INTERRUPT CONTROL REGISTER (ADDRESS: 0Bh, 8Bh, 10Bh OR
18Bh)
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
T0IE: TMR0 Overflow Interrupt Enable bit
1 = Enables the TMR0 interrupt
0 = Disables the TMR0 interrupt
INTE: RB0/INT/SEG0 External Interrupt Enable bit
1 = Enables the RB0/INT/SEG0 external interrupt
0 = Disables the RB0/INT/SEF0 external interrupt
RBIE: PORTB Change Interrupt Enable bit
1 = Enables the PORTB change interrupt
0 = Disables the PORTB change interrupt
T0IF: TMR0 Overflow Interrupt Flag bit
1 = TMR0 register has overflowed (must be cleared in software)
0 = TMR0 register did not overflow
INTF: RB0/INT/SEG0 External Interrupt Flag bit
1 = The RB0/INT/SEG0 external interrupt occurred (must be cleared in software)
0 = The RB0/INT/SEG0 external interrupt did not occur
RBIF: PORTB Change Interrupt Flag bit
1 = When at least one of the PORTB <5:0> pins changed state (must be cleared in software)
0 = None of the PORTB <7:4> pins have changed state
Legend:
R = Readable bit
- n = Value at POR

Note 1: IOCB register must also be enabled.

2: T0IF bit is set when Timer0 rolls over. Timer0 is unchanged on Reset and should
be initialized before clearing T0IF bit.

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.
