Question

What is the use of the prescalar in the operation of the timer?

(a) for fast calculations

(b) for increasing the time delay given by the timer by decreasing its frequency of operation

(c) for removing the concept the reloading of count

(d) for easy counter operations

This question was addressed to me during an internship interview.

I would like to ask this question from Timer Programming in section AVR Microcontroller of Microcontroller

Answer 1

Correct option is (b) for increasing the time delay given by the timer by decreasing its frequency of operation

Easiest explanation: Prescalars are used in the operation of the timers because they generally increase the time delay generation by decreasing the frequency of its operation.
