Many of the GPIO port pins are used as interrupt sources. Some port pins are configured
to generate an interrupt request on either the rising edge or falling edge of the input pin
signal. Other port pin interrupt sources, generate an interrupt when any edge occurs (both
rising and falling). For more details on interrupts using the GPIO pins, see
Controller
