Hello

Yes using an interrupt icon you can enable an interrupt to call a macro on a particular event for example on a raising or falling edge of an input pin.

Once the interrupt fires you have some options on what to do. Here are some potential options. You could disable the outputs and set a variable that can be acted upon in the main loop. You could disable the outputs and then enter an infinite loop that forces you to hard reset to bring operation back. You could do a soft reset.
