WebThe external interrupt pins allow software to specify whether the interrupt should be triggered by a rising edge or by a falling edge; if e.g. a pin is low and one is interested in falling edges only, an interrupt will not be triggered until the pin rises and subsquently falls. Using interrupt-on-change, one would have to wake up on both events.

So if you have low-level interrupt set, MCU will keep executing the ISR as long as the pin is low. That is, it will leave and re-enter the ISR again and again, as long as the pin is low. japan festival of lights
