INTCON REGISTER
The INTCON Register is a readable and writable regis-
ter which contains various enable and ag bits for the
TMR0 register overow, RB Port change and External
RB0/INT pin interrupts.
FIGURE 2-5:
INTCON REGISTER (ADDRESS 0Bh, 8Bh)
Note:
Interrupt ag bits get set when an interrupt
condition occurs regardless of the state of
its corresponding enable bit or the global
enable bit, GIE (INTCON<7>). User soft-
ware should ensure the appropriate inter-
rupt ag bits are clear prior to enabling an
interrupt.

bit 7:
GIE: Global Interrupt Enable bit
1 = Enables all un-masked interrupts
0 = Disables all interrupts
bit 6:
PEIE: Peripheral Interrupt Enable bit
1 = Enables all un-masked peripheral interrupts
0 = Disables all peripheral interrupts
bit 5:
T0IE: TMR0 Overow Interrupt Enable bit
1 = Enables the TMR0 interrupt
0 = Disables the TMR0 interrupt
bit 4:
INTE: RB0/INT External Interrupt Enable bit
1 = Enables the RB0/INT external interrupt
0 = Disables the RB0/INT external interrupt
bit 3:
RBIE: RB Port Change Interrupt Enable bit
1 = Enables the RB port change interrupt
0 = Disables the RB port change interrupt
bit 2:
T0IF: TMR0 Overow Interrupt Flag bit
1 = TMR0 register has overowed (must be cleared in software)
0 = TMR0 register did not overow
bit 1:
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
bit 0:
RBIF: RB Port Change Interrupt Flag bit
1 = At least one of the RB7:RB4 pins changed state (must be cleared in software)
0 = None of the RB7:RB4 pins have changed state
