Abstract
A control circuit including a quadrature encoder circuit, a counter circuit, and a cutoff circuit is provided. The quadrature encoder circuit generates a first edge signal and a first direction signal according to a first external signal and a second external signal. The counter circuit performs a counting operation according to the first edge signal and the first direction signal. In response to the timer signal being enabled, the cutoff circuit prevents the first edge signal and the first direction signal from entering the counter circuit and provides a second edge signal and a second direction signal to the counter circuit so that the counter circuit performs the counting operation according to the second edge signal and the second direction signal.
