Perbedaan antara Timer dan Counter Timer: Sumber detak dari internal.

Counter: Sumber detak dari eksternal/pin.

Fitur TIMERs ATmega16A

Nilai prescaler adalah perkalian jumlah detak/input yang diperlukan untuk 1x pencacahan nilai Timer/Counter.

Semakin besar nilai prescaler, maka semakin lama terpenuhinya nilai Timer/Counter.

Prescaler Factor:
