                        ##### How to use this driver #####
  ==============================================================================
  [..]
    This driver implements a high level communication layer for read and write from/to 
    this memory. The needed STM32 hardware resources (SDMMC1 and GPIO) are performed by 
    the user in HAL_SD_MspInit() function (MSP layer).                             
    Basically, the MSP layer configuration should be the same as we provide in the 
    examples.
    You can easily tailor this configuration according to hardware resources.

  [..]
    This driver is a generic layered driver for SDMMC memories which uses the HAL 
    SDMMC driver functions to interface with SD and uSD cards devices. 
    It is used as follows:
 
    (#)Initialize the SDMMC1 low level resources by implementing the HAL_SD_MspInit() API:
        (##) Call the function HAL_RCCEx_PeriphCLKConfig with RCC_PERIPHCLK_SDMMC1 for
        PeriphClockSelection and select SDMMC1 clock source (MSI, main PLL or PLLSAI1)
        (##) Enable the SDMMC1 interface clock using __HAL_RCC_SDMMC1_CLK_ENABLE(); 
        (##) SDMMC pins configuration for SD card
            (+++) Enable the clock for the SDMMC GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();   
            (+++) Configure these SDMMC pins as alternate function pull-up using HAL_GPIO_Init()
                  and according to your pin assignment;
        (##) On STM32L4Rx/STM32L4Sxx devices, no DMA configuration is need, an internal DMA for SDMMC IP is used.
        (##) On other devices, perform DMA configuration if you need to use DMA process (HAL_SD_ReadBlocks_DMA()
             and HAL_SD_WriteBlocks_DMA() APIs).
            (+++) Enable the DMAx interface clock using __HAL_RCC_DMAx_CLK_ENABLE(); 
            (+++) Configure the DMA using the function HAL_DMA_Init() with predeclared and filled. 
        (##) NVIC configuration if you need to use interrupt process when using DMA transfer.
            (+++) Configure the SDMMC and DMA interrupt priorities using functions
                  HAL_NVIC_SetPriority(); DMA priority is superior to SDMMC's priority
            (+++) Enable the NVIC DMA and SDMMC IRQs using function HAL_NVIC_EnableIRQ()
            (+++) SDMMC interrupts are managed using the macros __HAL_SD_ENABLE_IT() 
                  and __HAL_SD_DISABLE_IT() inside the communication process.
            (+++) SDMMC interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
                  and __HAL_SD_CLEAR_IT()
        (##) NVIC configuration if you need to use interrupt process (HAL_SD_ReadBlocks_IT()
             and HAL_SD_WriteBlocks_IT() APIs).
            (+++) Configure the SDMMC interrupt priorities using function
                  HAL_NVIC_SetPriority();
            (+++) Enable the NVIC SDMMC IRQs using function HAL_NVIC_EnableIRQ()
            (+++) SDMMC interrupts are managed using the macros __HAL_SD_ENABLE_IT() 
                  and __HAL_SD_DISABLE_IT() inside the communication process.
            (+++) SDMMC interrupts pending bits are managed using the macros __HAL_SD_GET_IT()
                  and __HAL_SD_CLEAR_IT()
    (#) At this stage, you can perform SD read/write/erase operations after SD card initialization  

         
  *** SD Card Initialization and configuration ***
  ================================================    
  [..]
    To initialize the SD Card, use the HAL_SD_Init() function.  It Initializes 
    SDMMC IP(STM32 side) and the SD Card, and put it into StandBy State (Ready for data transfer). 
    This function provide the following operations:
  
    (#) Initialize the SDMMC peripheral interface with defaullt configuration.
        The initialization process is done at 400KHz. You can change or adapt 
        this frequency by adjusting the "ClockDiv" field. 
        The SD Card frequency (SDMMC_CK) is computed as follows:

           SDMMC_CK = SDMMCCLK / (ClockDiv + 2)

        In initialization mode and according to the SD Card standard, 
          make sure that the SDMMC_CK frequency doesn't exceed 400KHz.
  
        This phase of initialization is done through SDMMC_Init() and 
        SDMMC_PowerState_ON() SDMMC low level APIs.
        
    (#) Initialize the SD card. The API used is HAL_SD_InitCard().
        This phase allows the card initialization and identification 
        and check the SD Card type (Standard Capacity or High Capacity)
        The initialization flow is compatible with SD standard.

        This API (HAL_SD_InitCard()) could be used also to reinitialize the card in case 
        of plug-off plug-in.
  
    (#) Configure the SD Card Data transfer frequency. By Default, the card transfer 
        frequency is set to 24MHz. You can change or adapt this frequency by adjusting 
        the "ClockDiv" field.
        In transfer mode and according to the SD Card standard, make sure that the 
        SDMMC_CK frequency doesn't exceed 25MHz and 50MHz in High-speed mode switch.
        To be able to use a frequency higher than 24MHz, you should use the SDMMC 
        peripheral in bypass mode. Refer to the corresponding reference manual 
        for more details.
  
    (#) Select the corresponding SD Card according to the address read with the step 2.
    
    (#) Configure the SD Card in wide bus mode: 4-bits data.

  [..] 
    (+) You can read from SD card in polling mode by using function HAL_SD_ReadBlocks(). 
        This function allows the read of 512 bytes blocks.
        You can choose either one block read operation or multiple block read operation 
        by adjusting the "NumberOfBlocks" parameter.
        After this, you have to ensure that the transfer is done correctly. The check is done
        through HAL_SD_GetCardState() function for SD card state.

    (+) You can read from SD card in DMA mode by using function HAL_SD_ReadBlocks_DMA().
        This function allows the read of 512 bytes blocks.
        You can choose either one block read operation or multiple block read operation 
        by adjusting the "NumberOfBlocks" parameter.
        After this, you have to ensure that the transfer is done correctly. The check is done
        through HAL_SD_GetCardState() function for SD card state.
        You could also check the DMA transfer process through the SD Rx interrupt event.

    (+) You can read from SD card in Interrupt mode by using function HAL_SD_ReadBlocks_IT().
        This function allows the read of 512 bytes blocks.
        You can choose either one block read operation or multiple block read operation

  *** SD card status ***
  ====================== 
  [..]
    (+) The SD Status contains status bits that are related to the SD Memory 
        Card proprietary features. To get SD card status use the HAL_SD_GetCardStatus().

  *** SD card information ***

    (@) You can refer to the SD HAL driver header file for more useful macros 
      
  *** Callback registration ***
  =============================================
  [..]
    The compilation define USE_HAL_SD_REGISTER_CALLBACKS when set to 1
    allows the user to configure dynamically the driver callbacks.

    Use Functions @ref HAL_SD_RegisterCallback() to register a user callback,
    it allows to register following callbacks:
      (+) TxCpltCallback : callback when a transmission transfer is completed.
      (+) RxCpltCallback : callback when a reception transfer is completed.
      (+) ErrorCallback : callback when error occurs.
      (+) AbortCpltCallback : callback when abort is completed.
      (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed.
      (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed.
      (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed.
      (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed.
      (+) MspInitCallback    : SD MspInit.
      (+) MspDeInitCallback  : SD MspDeInit.
    This function takes as parameters the HAL peripheral handle, the Callback ID
    and a pointer to the user callback function.
    For specific callbacks TransceiverCallback use dedicated register callbacks:   
    respectively @ref HAL_SD_RegisterTransceiverCallback().

    Use function @ref HAL_SD_UnRegisterCallback() to reset a callback to the default
    weak (surcharged) function. It allows to reset following callbacks:
      (+) TxCpltCallback : callback when a transmission transfer is completed.
      (+) RxCpltCallback : callback when a reception transfer is completed.
      (+) ErrorCallback : callback when error occurs.
      (+) AbortCpltCallback : callback when abort is completed.
      (+) Read_DMADblBuf0CpltCallback : callback when the DMA reception of first buffer is completed.
      (+) Read_DMADblBuf1CpltCallback : callback when the DMA reception of second buffer is completed.
      (+) Write_DMADblBuf0CpltCallback : callback when the DMA transmission of first buffer is completed.
      (+) Write_DMADblBuf1CpltCallback : callback when the DMA transmission of second buffer is completed.
      (+) MspInitCallback    : SD MspInit.
      (+) MspDeInitCallback  : SD MspDeInit.
    This function) takes as parameters the HAL peripheral handle and the Callback ID.
    For specific callbacks TransceiverCallback use dedicated unregister callbacks:       
    respectively @ref HAL_SD_UnRegisterTransceiverCallback().

    By default, after the @ref HAL_SD_Init and if the state is HAL_SD_STATE_RESET
    all callbacks are reset to the corresponding legacy weak (surcharged) functions.
    Exception done for MspInit and MspDeInit callbacks that are respectively
    reset to the legacy weak (surcharged) functions in the @ref HAL_SD_Init 
    and @ref  HAL_SD_DeInit only when these callbacks are null (not registered beforehand).
    If not, MspInit or MspDeInit are not null, the @ref HAL_SD_Init and @ref HAL_SD_DeInit
    keep and use the user MspInit/MspDeInit callbacks (registered beforehand)

    Callbacks can be registered/unregistered in READY state only.
    Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
    in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
    during the Init/DeInit.
    In that case first register the MspInit/MspDeInit user callbacks
    using @ref HAL_SD_RegisterCallback before calling @ref HAL_SD_DeInit 
    or @ref HAL_SD_Init function.

    When The compilation define USE_HAL_SD_REGISTER_CALLBACKS is set to 0 or
    not defined, the callback registering feature is not available 
    and weak (surcharged) callbacks are used.
