Can a single pin trigger an interrupt on rising and falling edges ?

I need to set up an interrrupt on the positive going edge of a signal, then while in the interrupt service routine, modify the configuration·to next trigger on the negative going edge and vice-versa.· Does anyone know if this will work or am I forced·to use two input pins to get the job done?

    The answer to your question is on page 92 in the SX-Key Development System Manual. My interpretation, is that yes , you can do it.
