Can anyone shed some light on this problem please? It's likely to be something simple that I've overlooked.
I'm using MPLAB 7.5 running on XP SP2. It's simple assembly code that services INT0 on the falling edge of port RC0 and services INT1 on the falling edge of RC2.
Everything works OK except that should RC2 become active while INT0 is being serviced, as soon as the INT0 ISR completes, INT1 ISR runs directly after. The same applies the other-way-round.
So, at the beginning of both service routines I disable the global interrupt bit (BCF INTCON,GIE) then re-enable just before RETFIE. However, this doesn't seem to prevent RC2 activity during INT0 ISR and of course the same applies for RC0 during INT1 ISR.
Thanks for any pointers. Simon
