Detailed explanation-1: -The timer can be used to measure the time elapsed or the external events occurring for a specific time interval. They are used to maintain the operation of the embedded system in sync with the clock. The clock can be an external clock or the system clock.
Detailed explanation-2: -A timer uses the frequency of the internal clock, and generates delay. A counter uses an external signal to count pulses.
Detailed explanation-3: -Explanation: If Timer 0 is to be used as a counter, then a pulse has to be applied at P3. 4 and if it is for Timer 1 then the clock pulse has to be applied at the pin P3.
Detailed explanation-4: -Get the clock from the FOSC/4 and then going to the Prescaler. Then this clock frequency is given to the TMR2 register, it will count the incoming clock pulse. As it is counting the incoming clock pulses the value present in the TMR2 register is also compared with PR2 register. More items
