In an embodiment, a motor driver comprises a multipurpose pin operable to couple the motor driver to a controller and judgment logic coupled to the multipurpose pin. The motor driver is operable to receive an input signal via the multipurpose pin and may be operable in a normal operation mode or a setting operation mode. The judgment logic may be operable to detect whether a prescribed pattern is present in the input signal, wherein the prescribed pattern indicates one of the normal operation mode or the setting operation mode, control at least a portion of the motor driver to operate in the setting operation mode when the prescribed pattern is detected in the input signal, and control at least the portion of the motor driver to operate in the normal operation mode when the prescribed pattern is not detected in the input signal.
