Hi

Yes, when i'm done in my interrupt handler i reset the T0IF bit, but still
the timerinterrupts occurs. There is a little delay between them, as if the
pic is really counting some sort of signal. Basicly I use the same
handlersource for the timerinterrupt and the RB0 interrupt,  and the RB0
interrupt works just fine.

Hi!

Do you reset the T0IF bit in the INTCON register upon entry
into your interrupt routine? This bit has to be reset
by software, or you will get a new interrupt every time
the timer 0 int gets enabled again (e.g. by RETFIE).
