Answer:

"Counter are used as Timer"

Explanation:

Counters, which in some sense can be called timers, are one of the most important sub-functions of a microcontroller. These enable to precisely time processes, generate signals and count events. A counter converts the number of input cycles to a binary value using an array of triggers. The maximum number of counted cycles depends on the length of this array, and this is marked by the length of the binary code. AVR has 8- and 16-bit counters. If a timer has reached its maximum value (255 in 8-bit and 65535 in 16-bit counters), the next cycle will generate an overflow and the counter resets back to 0. A counter's clock signal can come from the clock signal of the microcontroller, and in this case it is possible to decrease its value using a prescaler. Some AVRs have an internal independent clock signal generator, which can be modified to run faster using a frequency multiplier. Counters also differ in application cases and work modes.
