Explanation:
Detailed explanation-1: -T0TCR (Timer0 Timer Control Register) It is an 8-bit read-write register. It is used to control the operation of the timer counter.
Detailed explanation-2: -The operation of timer 0 is straight forward. The TCNT0 register hold the timer Count and it is incremented on every timer “tick". If the timer is turned on it ticks from 0 to 255 and overflows. If it does so, a Timer OverFlow Flag(TOV) is set.
Detailed explanation-3: -Mode 0 of Timer/Counter The Mode 0 operation is the 8-bit timer or counter with a 5-bit pre-scaler. So it is a 13-bit timer/counter. It uses 5 bits of TL0 or TL1 and all of the 8-bits of TH0 or TH1.
