Before going for the details of Timer configurations, it is important to learn how time delay … WebNov 24, 2016 · F timer = 5 MHz/256 =19531.25Hz. Single overflow of Timer0 will give this delay: T timer = 1/19531.25 = 0.0000512 sec = 51.2 µs. This means that when timer runs, it will take 51 µs to increment its value at every count. Now we have to calculate the value to be filled in Timer register to generate 1 sec delay. ridge\u0027s gv
