* @brief Set ADC low power mode.

* has been retrieved by user software.

* This mode allows to automatically adapt the ADC conversions
* triggers to the speed of the software that reads the data.
* Moreover, this avoids risk of overrun for low frequency
* applications.
* How to use this low power mode:
* - Do not use with interruption or DMA since these modes
* have to clear immediately the EOC flag to free the
* IRQ vector sequencer.
* - Do use with polling: 1. Start conversion,
* 2. Later on, when conversion data is needed: poll for end of
* conversion to ensure that conversion is completed and
* retrieve ADC conversion data. This will trig another
* ADC conversion start.
* - ADC low power mode "auto power-off" (feature available on
* this device if parameter LL_ADC_LP_MODE_AUTOOFF is available):
* the ADC automatically powers-off after a conversion and
* automatically wakes up when a new conversion is triggered
* (with startup time between trigger and start of sampling).
* This feature can be combined with low power mode "auto wait".
* @note With ADC low power mode "auto wait", the ADC conversion data read
* is corresponding to previous ADC conversion start, independently
* of delay during which ADC was idle.
* Therefore, the ADC conversion data may be outdated: does not
