Function Documentation

__STATIC_INLINE void LL_LPTIM_ConfigClock	(	LPTIM_TypeDef *	LPTIMx,
		uint32_t	ClockFilter,
		uint32_t	ClockPolarity
	)

Configure the active edge or edges used by the counter when the LPTIM is clocked by an external clock source.

Note:

This function must be called when the LPTIM instance is disabled.

When both external clock signal edges are considered active ones, the LPTIM must also be clocked by an internal clock source with a frequency equal to at least four times the external clock frequency.

An internal clock source must be present when a digital filter is required for external clock.
