  65.   *          - Scope channel: InjectedChannel, InjectedRank, InjectedSamplingTime, InjectedOffset
  66.   *          - Scope injected group (affects all channels of injected group): InjectedNbrOfConversion, InjectedDiscontinuousConvMode,

  68.   * @note   The setting of these parameters with function HAL_ADCEx_InjectedConfigChannel() is conditioned to ADC state.
