INTCON REGISTER

Note:

Interrupt 铿俛g 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>).

The INTCON register is a readable and writable

for all non-peripheral interrupt sources.

PEIE:

Peripheral Interrupt Enable bit

1 = Enables all un-masked peripheral interrupts

0 = Disables all peripheral interrupts

T0IE:

TMR0 Over铿俹w Interrupt Enable bit

1 = Enables the TMR0 interrupt

RBIE:

RB Port Change Interrupt Enable bit

1 = Enables the RB port change interrupt

0 = Disables the RB port change interrupt

T0IF:

TMR0 Over铿俹w Interrupt Flag bit

1 = TMR0 register over铿俹wed (must be cleared in software)

0 = TMR0 register did not over铿俹w

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

1 = When at least one of the RB7:RB4 pins changed state (See Section 5.2 to clear interrupt)

0 = None of the RB7:RB4 pins have changed state
