  *           @ref LL_DAC_ConvertData8RightAligned
  *         or one of the supported autogenerated wave.
  * @note   This function allows configuration of:
  *          - Output mode
  *          - Trigger
  *          - Wave generation
  * @note   The setting of these parameters by function @ref LL_DAC_Init()
  *         is conditioned to DAC state:
  *         DAC channel must be disabled.
  * @param  DACx DAC instance
  * @param  DAC_Channel This parameter can be one of the following values:
  *         @arg @ref LL_DAC_CHANNEL_1
  *         @arg @ref LL_DAC_CHANNEL_2 (1)
  *
  *         (1) On this STM32 series, parameter not available on all instances.
  *             Refer to device datasheet for channels availability.
  * @param  DAC_InitStruct Pointer to a @ref LL_DAC_InitTypeDef structure
  * @retval An ErrorStatus enumeration value:
  *          - SUCCESS: DAC registers are initialized
