__STATIC_INLINE void LL_LPTIM_ConfigOutput	(	LPTIM_TypeDef *	LPTIMx,
		uint32_t	Waveform,
		uint32_t	Polarity
	)

Configure the LPTIM instance output (LPTIMx_OUT)

Note:: This function must be called when the LPTIM instance is disabled.; Regarding the LPTIM output polarity the change takes effect immediately, so the output default value will change immediately after the polarity is re-configured, even before the timer is enabled.
