WebNov 27, 2000 · Start the debugger. Set a breakpoint on the overflow_count++ line in the ISR. Run the program. Each time the interrupt routine is invoked, the debugger stops running the program. Position the cursor over the overflow_count variable to view its current value. 8051_TIMER0.ZIP (8.7K) Monday, November 27, 2000. WebAs soon as the supply is switched on, the microcontroller AT89C51 starts counting from 0 to 9999. The counter is incremented by one after a delay of one second. To produce this delay Timer1 has been used. After every 2.5 millisecond the Timer0 interrupt function is called and the value of the counter is displayed as per the explanation earlier.
