  *         (functions with prefix "INJ").
  * @note   The setting of these parameters by function @ref LL_ADC_Init()

  *         ADC instance must be disabled.
  *         This condition is applied to all ADC features, for efficiency
  *         and compatibility over all STM32 families. However, the different
  *         features can be set under different ADC state conditions
  *         (setting possible with ADC enabled without conversion on going,
  *         ADC enabled with conversion on going, ...)
  *         Each feature can be updated afterwards with a unitary function
  *         and potentially with ADC in a different state than disabled,
  *         refer to description of each function for setting
  *         conditioned to ADC state.
  * @note   After using this function, other features must be configured
  *         using LL unitary functions.
  *         The minimum configuration remaining to be done is:
  *          - Set ADC group injected sequencer:
  *            map channel on the selected sequencer rank.
  *            Refer to function @ref LL_ADC_INJ_SetSequencerRanks().
