__STATIC_INLINE void LL_ADC_ConfigAnalogWDThresholds	(	ADC_TypeDef *	ADCx,
		uint32_t	AWDy,
		uint32_t	AWDThresholdHighValue,
		uint32_t	AWDThresholdLowValue
	)

Set ADC analog watchdog thresholds value of both thresholds high and low.

Note:

If value of only one threshold high or low must be set, use function LL_ADC_SetAnalogWDThresholds().

In case of ADC resolution different of 12 bits, analog watchdog thresholds data require a specific shift. Use helper macro __LL_ADC_ANALOGWD_SET_THRESHOLD_RESOLUTION().

On this STM32 serie, there are 2 kinds of analog watchdog instance:

AWD standard (instance AWD1):
- channels monitored: can monitor 1 channel or all channels.
- groups monitored: ADC groups regular and-or injected.
- resolution: resolution is not limited (corresponds to ADC resolution configured).
AWD flexible (instances AWD2, AWD3):
- channels monitored: flexible on channels monitored, selection is channel wise, from from 1 to all channels. Specificity of this analog watchdog: Multiple channels can be selected. For example: (LL_ADC_AWD_CHANNEL4_REG_INJ | LL_ADC_AWD_CHANNEL5_REG_INJ | ...)
- groups monitored: not selection possible (monitoring on both groups regular and injected). Channels selected are monitored on groups regular and injected: LL_ADC_AWD_CHANNELxx_REG_INJ (do not use parameters LL_ADC_AWD_CHANNELxx_REG and LL_ADC_AWD_CHANNELxx_INJ)
- resolution: resolution is limited to 8 bits: if ADC resolution is 12 bits the 4 LSB are ignored, if ADC resolution is 10 bits the 2 LSB are ignored.

On this STM32 serie, setting of this feature is conditioned to ADC state: ADC must be disabled or enabled without conversion on going on either groups regular or injected.

__STATIC_INLINE uint32_t LL_ADC_GetAnalogWDMonitChannels	(	ADC_TypeDef *	ADCx,
		uint32_t	AWDy
	)

Get ADC analog watchdog monitored channel.

Note:

Usage of the returned channel number:

To reinject this channel into another function LL_ADC_xxx: the returned channel number is only partly formatted on definition of literals LL_ADC_CHANNEL_x. Therefore, it has to be compared with parts of literals LL_ADC_CHANNEL_x or using helper macro __LL_ADC_CHANNEL_TO_DECIMAL_NB(). Then the selected literal LL_ADC_CHANNEL_x can be used as parameter for another function.
To get the channel number in decimal format: process the returned value with the helper macro __LL_ADC_CHANNEL_TO_DECIMAL_NB(). Applicable only when the analog watchdog is set to monitor one channel.

On this STM32 serie, there are 2 kinds of analog watchdog instance:

AWD standard (instance AWD1):
- channels monitored: can monitor 1 channel or all channels.
- groups monitored: ADC groups regular and-or injected.
- resolution: resolution is not limited (corresponds to ADC resolution configured).
AWD flexible (instances AWD2, AWD3):
- channels monitored: flexible on channels monitored, selection is channel wise, from from 1 to all channels. Specificity of this analog watchdog: Multiple channels can be selected. For example: (LL_ADC_AWD_CHANNEL4_REG_INJ | LL_ADC_AWD_CHANNEL5_REG_INJ | ...)
- groups monitored: not selection possible (monitoring on both groups regular and injected). Channels selected are monitored on groups regular and injected: LL_ADC_AWD_CHANNELxx_REG_INJ (do not use parameters LL_ADC_AWD_CHANNELxx_REG and LL_ADC_AWD_CHANNELxx_INJ)
- resolution: resolution is limited to 8 bits: if ADC resolution is 12 bits the 4 LSB are ignored, if ADC resolution is 10 bits the 2 LSB are ignored.

On this STM32 serie, setting of this feature is conditioned to ADC state: ADC must be disabled or enabled without conversion on going on either groups regular or injected.
