==============================================================================
##### SDADC specific features #####
==============================================================================
[..]
(#) 16-bit sigma delta architecture.
(#) 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).
(#) DMA request generation during regular or injected channel conversion.
##### How to use this driver #####
==============================================================================
[..]
*** Initialization ***
======================
[..]
(#) As prerequisite, fill in the HAL_SDADC_MspInit() :
(++) Enable SDADCx clock interface with __SDADCx_CLK_ENABLE().
(++) Configure SDADCx clock divider with HAL_RCCEx_PeriphCLKConfig.
(++) Enable power on SDADC with HAL_PWREx_EnableSDADC().
(++) Enable the clocks for the SDADC GPIOS with __HAL_RCC_GPIOx_CLK_ENABLE().
(++) Configure these SDADC pins in analog mode using HAL_GPIO_Init().
(++) If interrupt mode is used, enable and configure SDADC global
interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
(++) If DMA mode is used, configure DMA with HAL_DMA_Init and link it
with SDADC handle using __HAL_LINKDMA.
(#) Configure the SDADC low power mode, fast conversion mode, slow clock
mode and SDADC1 reference voltage using the HAL_ADC_Init() function.
Note: Common reference voltage. is common to all SDADC instances.
(#) Prepare channel configurations (input mode, common mode, gain and
offset) using HAL_SDADC_PrepareChannelConfig and associate channel
with one configuration using HAL_SDADC_AssociateChannelConfig.
*** Calibration ***
============================================
[..]
(#) Start calibration using HAL_SDADC_StartCalibration or
HAL_SDADC_CalibrationStart_IT.
(#) In polling mode, use HAL_SDADC_PollForCalibEvent to detect the end of
calibration.

the end of calibration.
