                    ##### SDADC specific features #####
  ==============================================================================

  (#) Self calibration.
  (#) Interrupt generation at the end of calibration, regular/injected conversion  
      and in case of overrun events.
  (#) Single and continuous conversion modes.
  (#) External trigger option with configurable polarity for injected conversion.
  (#) Multi mode (synchronized another SDADC with SDADC1).

            interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().

          mode and SDADC1 reference voltage using the HAL_ADC_Init() function.
