Abstract: A The present invention provides a semiconductor device, an electrical device, and a control signal generation method that enable easy generation of a given control signal even by a comparatively low cost and low processing power microcontroller, whereby a microcontroller of a motor control system includes a PWM device equipped with a PWM setting register. The PWM setting register includes a duty update cycle register, a duty update value register and a duty update-times number register. A PWM generator generates and outputs a PWM signal according to values set in each register of the PWM setting register. The PWM device is capable of generating and outputting a PWM signal automatically with the PWM generator according to setting values set in the PWM setting register, even without an interruption by the software (CPU).
