Read anytime. This register cannot be modified after the WP bit is set.
A normal PWM output or positive polarity means that the PWM channel outputs high when the counter
value is smaller than or equal to the pulse width value and outputs low otherwise. An inverted output or
negative polarity means that the PWM channel outputs low when the counter value is smaller than or equal
to the pulse width value and outputs high otherwise.
