Well I not sure whether this will work for you or not, why not use say 6
PORT pin to detect your signal, and with different pin set, call up
different function that you want to run?

Subject: [avr-gcc-list] external interrupt use
Hi all,
I have 6 digital signals that I need to be able to trigger an interrupt on
the falling edge and rising edge for all of them, but I am short 2 external
interrupts. Is there a simple way to detect the 6 signals rising/falling
edges with 4 interrupts and some additional circuitry? I have thought about
using diodes to AND some of the signals but this only works for positive
edges I think.
cheers,
Jamie Morken
