Notes
This function enables clearing the output channel on an external event. This function can only be used in Output compare and PWM modes. It does not work in Forced mode. Macro IS_TIM_OCXREF_CLEAR_INSTANCE(TIMx) can be used to check whether or not a timer instance can clear the OCxREF signal on an external event.
