Set ADC continuous conversion mode on ADC group regular, whether ADC conversions are performed in single mode (one conversion per trigger) or in continuous mode (after the first trigger, following conversions launched successively automatically). This parameter can be a value of ADC_LL_EC_REG_CONTINUOUS_MODE Note: It is not possible to enable both ADC group regular continuous mode and discontinuous mode. This feature can be modified afterwards using unitary function LL_ADC_REG_SetContinuousMode().
