typename SelfType::ValueType pwm_counter_enabled ()

Enables the PWM counter logic. When disabled, the PWM is always inactive.

SelfType & set_pwm_counter_enabled (typename SelfType::ValueType val)

Enables the PWM counter logic. When disabled, the PWM is always inactive.

template <, >

typename SelfType::ValueType pwm_polarity_inverted ()

Inverts whether the backlight PWM active duty drives the PWM pin high/low.

When 0 (default), the backlight PWM pin is driven high when the PWM is in

active duty, and the pin is driven low when the PWM is inactive.

When 1 (inverted), the backlight PWM pin is driven low when the PWM is in

active duty, and the pin is driven high when the PWM is inactive.
