I've never heard of the 505f microcontroller, but I'm sure there are status registers or interrupt flag registers that your interrupt-service routine (ISR) can poll, in order of priority, to not only see what caused the interrupt(s), but to service them in order of importance or urgency if there was more than one at a time. Is there information about this microcontroller on the web? I'm interested.
