INTCON

Interrupt Control Register
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. User software may ensure the appropriate interrupt flag bits are clear prior to enabling an interrupt. This feature allows for software polling.
