Is it possible to pass any parameter and return a value from the ISR?
No. It is not possible to pass any parameter and return a value from the ISR. The ISR returns nothing and does not allow passing any parameter. An ISR is called when a hardware or software event occurs, and the code does not call it. That's why no parameters are passed into an ISR. As the code does not call ISR, there is no calling code to read the returned values of the ISR. That's why an ISR does not return any value.
