I want to use External INT in AVR but I want to do this state:
When I press EX INT for first time port b.0 is been “1” and stays in this state until I press EX INT for 2nd time and this state portb.0 is been “0” and port b.1 is been “1”and stays until I press EX INT for 3rd time .

By the way I want this program by codvision

Thanks a lot

Put a latching pushbutton on your external INT pin, and I don't see any
need for software in your problem statement. You don't seem to *do*
anything with the inputs.
