#187969 - More Interrupts
Responding to: ???'s previous message
Another feasible scheme is to externally use logic to OR two level type interrupts together and drive into a single INT pin. Also allocate two port pins to monitor the interrupt request signals in front of the OR logic. Within the ISR (interrupt service routine) you check the two port pins to see which source is requesting the interrupt.
