Generally devices have a minimum of three registers associated with interrupts. The INTCON
register which contains Global Interrupt Enable bit, GIE, as well as the Peripheral Interrupt
Enable bit, PEIE, and the PIE / PIR register pair which enable the peripheral interrupts and dis-
play the interrupt flag status.
The INTCON Register is a readable and writable register which contains various enable and flag
bits.
Register 8-1: INTCON Register
bit 7
GIE: Global Interrupt Enable bit
1 = Enables all un-masked interrupts
0 = Disables all interrupts
PEIE: Peripheral Interrupt Enable bit
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: INT External Interrupt Enable bit
1 = Enables the INT external interrupt
0 = Disables the INT external interrupt
RBIE
1 = Enables the RB port change interrupt
0 = Disables the RB port change interrupt
T0IF: TMR0 Overflow Interrupt Flag bit
1 = TMR0 register has overflowed (must be cleared in software)
0 = TMR0 register did not overflow
INTF: INT External Interrupt Flag bit
1 = The INT external interrupt occurred (must be cleared in software)
0 = The INT external interrupt did not occur
RBIF
1 = At least one of the RB7:RB4 pins changed state (must be cleared in software)
0 = None of the RB7:RB4 pins have changed state

R = Readable bit
U = Unimplemented bit, read as ‘0’

Note 1: In some devices, the RBIE bit may also be known as GPIE and the RBIF bit may be
Note 2: Some devices may not have this feature. For those devices this bit is reserved.
Note 3: In devices with only one peripheral interrupt, this bit may be EEIE or ADIE.

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>).This
feature allows for software polling.
