Answer 1

Counter/Timers in 8051 microcontroller

8051 microcontrollers have two timers: timer0 and timer1 which work on the clock frequency.
They can be used either as timers or as counters.
A timer/counter can be used for time delay generation, counting external events, etc.
Every Timer needs a clock to work, and 8051 provides it from an external crystal which is the main clock source for Timer.
The internal circuitry in the 8051 microcontrollers provides a clock source to the timers which are 1/12th of the frequency of the crystal attached to the microcontroller.
