hi to all. i am using 4*3 matrix keypad and i have to add an interrupt for reset button i.e.(*) button on keypad.in my program there is one led which gets on first and after some time gets off.when led is on and if i press reset(*) button led should off regardless of led on time.

please give me program for adding interrupt
 

We need schematic and source.... If (*) key is connected to matrix then will be problem generated interrupt....
Can you debug in system?
