What are the general uses for the PWM function?
Answer The frequency of the PWM function in the HT46 series of MCU devices is determined by the system frequency, however the duty cycle is controlled by the value loaded into the PWM register. The PWM is normally used in applications such as, speaker or buzzer driving, controlling current or voltage levels (e.g. for controlling illumination levels), DC motor rotational speed control, digital to analog converters etc.
