Problem with MPLAB

[ljcox]

I've successfully written many PIC programmes but this my first time with the 16F684.

I have MPLAB 8.92.

I cannot clear INTCON, 0. This instruction does not anything.
bcf INTCON, 0 ;RBIF

If I use this
clrf INTCON the INTCON value changes from 0x09 to 0x01. I have tried various tricks but to no avail.

I even uninstalled MPLAB & then re-installed it.

This instruction does clear INTCON, 1

bcf INTCON, 1 ;INTF

I feel that there is a software problem with MPLAB as I can't see any reason why it does not clear INTCON, 0

Any assistance will be appreciated.

INTCON = 0x09 says RAIE: PORTA Change Interrupt Enable bit
Datasheet clearly mentions about IOCA register. You have to clear IOCA4 register in order to disable RAIE interrupt.
