A PWM generating unit may include a base duty setting register configured to store a base duty value that is set thereto, and a PWM generator to obtain a corrected duty value by correcting the base duty value based on first correction data and second correction data, and to generate a PWM signal according to the corrected duty value. The first correction data may be computed from a rotation period of a first rotational body, and the second correction data may be computed from a rotation period of a second rotational body. |
