7.5.1 INTCON REGISTER

The INTCON register is a readable and writable

register, which contains the various enable and flag bits

for TMR0 register overflow, interrupt-on-change and

external INT pin interrupts.

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 software should ensure the

appropriate interrupt flag bits are clear

prior to enabling an interrupt.

Legend:

R = Readable bit

u = Bit is unchanged

‘1’ = Bit is set

W = Writable bit

x = Bit is unknown

‘0’ = Bit is cleared

U = Unimplemented bit, read as ‘0’

-n/n = Value at POR and BOR/Value at all other Resets

bit 7

GIE: Global Interrupt Enable bit

1 = Enables all active interrupts

0 = Disables all interrupts

bit 6

PEIE: Peripheral Interrupt Enable bit

1 = Enables all active peripheral interrupts

0 = Disables all peripheral interrupts

bit 5

TMR0IE: Timer0 Overflow Interrupt Enable bit

1 = Enables the Timer0 interrupt

0 = Disables the Timer0 interrupt

bit 4

INTE: INT External Interrupt Enable bit

1 = Enables the INT external interrupt

0 = Disables the INT external interrupt

bit 3

IOCIE: Interrupt-on-Change Interrupt Enable bit

1 = Enables the interrupt-on-change interrupt

0 = Disables the interrupt-on-change interrupt

bit 2

TMR0IF: Timer0 Overflow Interrupt Flag bit

1 = TMR0 register has overflowed

0 = TMR0 register did not overflow

bit 1

INTF: INT External Interrupt Flag bit

1 = The INT external interrupt occurred

0 = The INT external interrupt did not occur

bit 0

IOCIF: Interrupt-on-Change Interrupt Flag bit

1 = When at least one of the interrupt-on-change pins changed state

0 = None of the interrupt-on-change pins have changed state
