Assuming that you are reading the register in vertical blank/overscan etc, then you won't be able to tell the difference between that scenario and holding the button. This is effect the interferance case can cause. If you want to do edge detection, you can use the interrupt logic in the PIA(only for the joystick or paddle buttons).
