                        ##### 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 (SDIO 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 SDIO memories which uses the HAL
    SDIO driver functions to interface with SD and uSD cards devices.
    It is used as follows:

    (#)Initialize the SDIO low level resources by implement the HAL_SD_MspInit() API:
        (##) Enable the SDIO interface clock using __HAL_RCC_SDIO_CLK_ENABLE();
        (##) SDIO pins configuration for SD card
            (+++) Enable the clock for the SDIO GPIOs using the functions __HAL_RCC_GPIOx_CLK_ENABLE();
            (+++) Configure these SDIO pins as alternate function pull-up using HAL_GPIO_Init()
                  and according to your pin assignment;
        (##) 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 SDIO and DMA interrupt priorities using functions
                  HAL_NVIC_SetPriority(); DMA priority is superior to SDIO's priority
            (+++) Enable the NVIC DMA and SDIO IRQs using function HAL_NVIC_EnableIRQ()
            (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
                  and __HAL_SD_DISABLE_IT() inside the communication process.
            (+++) SDIO 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 SDIO interrupt priorities using function
                  HAL_NVIC_SetPriority();
            (+++) Enable the NVIC SDIO IRQs using function HAL_NVIC_EnableIRQ()
            (+++) SDIO interrupts are managed using the macros __HAL_SD_ENABLE_IT()
                  and __HAL_SD_DISABLE_IT() inside the communication process.
            (+++) SDIO 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
    SDIO 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 SDIO 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 (SDIO_CK) is computed as follows:

           SDIO_CK = SDIOCLK / (ClockDiv + 2)

        In initialization mode and according to the SD Card standard,
        make sure that the SDIO_CK frequency doesn't exceed 400KHz.

        This phase of initialization is done through SDIO_Init() and
        SDIO_PowerState_ON() SDIO 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
        SDIO_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 SDIO
        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.

  *** SD Card Read operation ***
  ==============================
  [..]
    (+) 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
        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 IT transfer process through the SD Rx interrupt event.

  *** SD Card Write operation ***
  ===============================
  [..]
    (+) You can write to SD card in polling mode by using function HAL_SD_WriteBlocks().
        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 write to SD card in DMA mode by using function HAL_SD_WriteBlocks_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 Tx interrupt event.

    (+) You can write to SD card in Interrupt mode by using function HAL_SD_WriteBlocks_IT().
        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 IT transfer process through the SD Tx interrupt event.

  *** 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 ***
  ===========================
  [..]
    (+) To get SD card information, you can use the function HAL_SD_GetCardInfo().
        It returns useful information about the SD card such as block size, card type,
        block number ...

  ============================
  [..]
    (+) The HAL_SD_GetCardCSD() API allows to get the parameters of the CSD register.
