4.2.2.3
The INTCON Register is a readable and writable regis-
ter which contains the various enable and flag bits for
the TMR0 register overflow, RB port change and exter-
nal RB0/INT pin interrupts.

GIE
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 software should ensure the appropriate interrupt flag bits are clear prior to
enabling an interrupt.
2: The PEIE bit (bit6) is unimplemented on the PIC16C61, read as '0'.
INTCON REGISTER
GIE:
1 = Enables all un-masked interrupts
0 = Disables all interrupts
PEIE:
1 = Enables all un-masked peripheral interrupts
0 = Disables all peripheral interrupts
T0IE: TMR0 Overflow Interrupt Enable bit
1 = Enables the TMR0 overflow interrupt
0 = Disables the TMR0 overflow 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
T0IF: TMR0 Overflow Interrupt Flag bit
1 = TMR0 register 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
1 = At least one of the RB7:RB4 pins changed state (see Section 5.2 to clear the interrupt)
0 = None of the RB7:RB4 pins have changed state
be re-enabled by the RETFIE instruction in the user’s Interrupt Service Routine. Refer to Section 13.5 for a detailed
description.
