INTCON Register
The INTCON Register is a readable and writable regis-
ter that contains various enable and flag bits for the
TMR0 register overflow, RB port change and external
RB0/INT pin interrupts.
REGISTER 2-3:
INTCON: INTERRUPT CONTROL REGISTER (ADDRESS 0Bh, 8Bh, 10Bh, 18Bh)

bit 7
Note:
Interrupt flag 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 flag bits are clear prior to enabling an
interrupt.

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
A mismatch condition will continue to set flag bit RBIF. Reading PORTB will end the mismatch
condition and allow flag bit RBIF to be cleared.
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

Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
