Abstract
A pulse width modulation (PWM) system includes a PWM circuit and a controller. The PWM circuit includes a counter, a period register, and a duty cycle register. The controller is coupled to the PWM circuit. The controller is configured to calculate a period value and a duty cycle value. The controller is also configured to load the duty cycle value into the duty cycle register responsive to a count value of the counter being equal to a value of the duty cycle register and the duty cycle value being less than the period value.
