4.2.2.3 INTCON Register

The INTCON register is a readable and writable

register, which contains the various enable and flag bits

for all interrupt sources except the comparator module.

See Section 4.2.2.4 “PIE1 Register” and

Section 4.2.2.5 “PIR1 Register” for a description of

the comparator enable and flag bits.

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>).

bit 7

bit 0

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 Overflow 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 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 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 = When at least one of the RB<7:4> pins changes state (must be cleared in software)

0 = None of the RB<7:4> 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
