4.5.1
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.

2:
The appropriate bits in the IOCB register must also be set.
T0IF bit is set when Timer0 rolls over. Timer0 is unchanged on Reset and should be initialized before
clearing T0IF bit.
INTCON REGISTER
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: Timer0 Overflow Interrupt Enable bit
1 = Enables the Timer0 interrupt
0 = Disables the Timer0 interrupt
INTE: RB0/INT External Interrupt Enable bit
1 = Enables the RB0/INT external interrupt
0 = Disables the RB0/INT external interrupt
RBIE: PORTB Change Interrupt Enable bit
1 = Enables the PORTB change interrupt
0 = Disables the PORTB change interrupt
T0IF: Timer0 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: PORTB Change Interrupt Flag bit
1 = When at least one of the PORTB general purpose I/O pins changed state (must be cleared in soft-
0 = None of the PORTB general purpose I/O pins have changed state

Note:
(1)
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 of the INTCON register.
User software should ensure the appropri-
ate interrupt flag bits are clear prior to
enabling an interrupt.
