so I just want to return to a specific address when ISR ends and the only solution in my mind is software reset but it is even good to reset my controller again and again?
I know you guys will be thinking why I need this thing. so I am working on fingerprint lock system, which displays stuff on LCD. in the ISR I will be changing passwords and enrolling new finger (have to clear LCD).and in the while loop it will ask the user to write a password. so when interrupt ISR ends there is a blank screen or just the last thing I wrote in ISR. that's why I want that when ISR ends it will start from while loop(more prefered then reset) so that it displays stuff even after ISR.
is there any solution?
