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, PORTA change and
external RA2/INT pin interrupts.

IOCA register must also be enabled.
T0IF bit is set when TMR0 rolls over. TMR0 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: RA2/INT External Interrupt Enable bit
1 = Enables the RA2/INT external interrupt
0 = Disables the RA2/INT external interrupt
RAIE: PORTA Change Interrupt Enable bit
1 = Enables the PORTA change interrupt
0 = Disables the PORTA change interrupt
T0IF: Timer0 Overflow Interrupt Flag bit
1 = Timer0 register has overflowed (must be cleared in software)
0 = Timer0 register did not overflow
INTF: RA2/INT External Interrupt Flag bit
1 = The RA2/INT external interrupt occurred (must be cleared in software)
0 = The RA2/INT external interrupt did not occur
RAIF: PORTA Change Interrupt Flag bit
1 = When at least one of the PORTA <5:0> pins changed state (must be cleared in software)
0 = None of the PORTA <5:0> pins have changed state

Note:
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
appropriate interrupt flag bits are clear
prior to enabling an interrupt.
