                                       This feature automatically adapts the frequency of ADC conversions triggers to the speed of the system that reads the data. Moreover, this avoids risk of overrun

                                       Note: In case of overrun set to data preserved and usage with programming model with interruption (HAL_Start_IT()): ADC IRQ handler has to clear 
                                       end of conversion flags, this induces the release of the preserved data. If needed, this data can be saved in function

                                             - Usage with ADC conversion by DMA: Error is reported whatever overrun setting (DMA is expected to process all data from data register). */
