INTCON Register
The INTCON Register is a readable and writable regis-
ter, which contains various enable and flag bits for the
TMR0 Register overflow, GPIO port change and exter-
nal GP2/INT pin interrupts.
REGISTER 4-3:
INTCON REGISTER (ADDRESS 0Bh, 8Bh)
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>).

GIE: Global Interrupt Enable bit
1
= Enables all unmasked interrupts
0
= Disables all interrupts
bit 6
PEIE: Peripheral Interrupt Enable bit
1
= Enables all unmasked peripheral interrupts
0
= Disables all peripheral interrupts
bit 5
T0IE: TMR0 Overflow Interrupt Enable bit
1
= Enables the TMR0 interrupt
0
= Disables the TMR0 interrupt
bit 4
INTE: INT External Interrupt Enable bit
1
= Enables the external interrupt on GP2/INT/T0CKI/AN2 pin
0
= Disables the external interrupt on GP2/INT/T0CKI/AN2 pin
bit 3
GPIE: GPIO Interrupt-on-Change Enable bit
1
= Enables the GPIO Interrupt-on-Change
0
= Disables the GPIO Interrupt-on-Change
bit 2
T0IF: TMR0 Overflow Interrupt Flag bit
1
= TMR0 register has overflowed (must be cleared in software)
0
= TMR0 register did not overflow
bit 1
INTF: RB0/INT External Interrupt Flag bit
1
= The external interrupt on GP2/INT/T0CKI/AN2 pin occurred (must be cleared in software)
0
= The external interrupt on GP2/INT/T0CKI/AN2 pin did not occur
bit 0
GPIF: GPIO Interrupt-on-Change Flag bit
1
= GP0, GP1 or GP3 pins changed state (must be cleared in software)
0
= Neither GP0, GP1 nor GP3 pins have changed state
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
- n = Value at POR
’1’ = Bit is set
’0’ = Bit is cleared
x = Bit is unknown
