This value delay is loaded into the high-byte of the timer/counter register. Out of this value the timer tries to reach the overflow. Before it can reach an overflow a compare match occurs and the suitable interrupt routine is called up. Because of this routine a led on the board flashes. Afterwards the timer runs to an overflow and carries out the overflow interrupt routine. The led is switched off again and the timer new is initialised with the value delay. Capture mode: This mode of operation enables to memorize the actual value of Timer/Counter 1 through an external signal.

In this case the do-while loop is left and the bontent of the variable led is written on PORTB. Afterwards the variable led is increased by one and checks if led is of the value $FF. In this case led is fixed to 0. Otherwise you have to write a one into register TIFR on position 6 , what has as a consequence that the TOV2 is deleted and the timer starts counting from the beginning. Interrupt mode: This mode of operation is used more often than the polling mode. In this case the TOV2 bit isn't constantly proved if it was set.
