Using INT pin as both INT and Digital input simulateously

I need to pin D2 to work as Digital Read while selecting and browsing through menus/modes and also need it to work as interrupt when used as STOP/PAUSE (while machine is working). Is it possible to do?

Yes. You can use Pin 2 to cause an interrupt and you can also use digitalRead() to read the state of the pin. Have a global variable you can set so the ISR can tell if you want to ignore the interrupt or not.
