Question

Write an AVR C-program that uses external interrupt INT0 and Timer1 output compare interrupt to implement a one-second one-digit stop clock. The stop clock should operate as follows:

When the circuit is powered on, it should display “0” continuously.
When the push button is pressed, the counter should start counting from “0” – “9”

at a rate of one second. When the count reaches “9”, it should reset to “0” and

continue counting.
If the push button is pressed again (the second time after power-on), the counter

should stop at the last digit that was displayed.
If the push button is pressed for a third time, the counter should continue counting

from the number that was on display.
