__STATIC_INLINE void LL_FMPI2C_ConfigFilters	(	FMPI2C_TypeDef *	FMPI2Cx,
		uint32_t	AnalogFilter,
		uint32_t	DigitalFilter
	)

Configure Noise Filters (Analog and Digital).

Note: If the analog filter is also enabled, the digital filter is added to analog filter. The filters can only be programmed when the FMPI2C is disabled (PE = 0). @rmtoll CR1 ANFOFF LL_FMPI2C_ConfigFilters
CR1 DNF LL_FMPI2C_ConfigFilters

Parameters

FMPI2Cx	FMPI2C Instance.
AnalogFilter	This parameter can be one of the following values: LL_FMPI2C_ANALOGFILTER_ENABLE LL_FMPI2C_ANALOGFILTER_DISABLE
DigitalFilter	This parameter must be a value between Min_Data=0x00 (Digital filter disabled) and Max_Data=0x0F (Digital filter enabled and filtering capability up to 15tfmpi2cclk). This parameter is used to configure the digital noise filter on SDA and SCL input. The digital filter will filter spikes with a length of up to DNF[3:0]tfmpi2cclk.

Return values
