  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================  
  (#) This driver is used to drive the micro SD external card mounted on STM3210E-EVAL 
     evaluation board.
     
  (#) This driver does not need a specific component driver for the micro SD device
     to be included with.

  (#) Initialization steps:
       (++) Initialize the micro SD card using the BSP_SD_Init() function. This 
            function includes the MSP layer hardware resources initialization and the
            SDIO interface configuration to interface with the external micro SD. It 
            also includes the micro SD initialization sequence.
       (++) To check the SD card presence you can use the function BSP_SD_IsDetected() which 
            returns the detection status 
       (++) If SD presence detection interrupt mode is desired, you must configure the 
            SD detection interrupt mode by calling the function BSP_SD_ITConfig(). The interrupt 
            is generated as an external interrupt whenever the micro SD card is 
            plugged/unplugged in/from the evaluation board. The SD detection interrupt
            is handeled by calling the function BSP_SD_DetectIT() which is called in the IRQ
            handler file, the user callback is implemented in the function BSP_SD_DetectCallback().
       (++) The function BSP_SD_GetCardInfo() is used to get the micro SD card information 
            which is stored in the structure "HAL_SD_CardInfoTypedef".
  
  (#) Micro SD card operations
       (++) The micro SD card can be accessed with read/write block(s) operations once 
            it is reay for access. The access cand be performed whether using the polling 
            mode by calling the functions BSP_SD_ReadBlocks()/BSP_SD_WriteBlocks(), or by DMA 
            transfer using the functions BSP_SD_ReadBlocks_DMA()/BSP_SD_WriteBlocks_DMA()
       (++) The DMA transfer complete is used with interrupt mode. Once the SD transfer
            is complete, the SD interrupt is handeled using the function BSP_SD_IRQHandler(),
            the DMA Tx/Rx transfer complete are handeled using the functions
            BSP_SD_DMA_Tx_IRQHandler()/BSP_SD_DMA_Rx_IRQHandler(). The corresponding user callbacks 
            are implemented by the user at application level. 
       (++) The SD erase block(s) is performed using the function BSP_SD_Erase() with specifying
            the number of blocks to erase.
       (++) The SD runtime status is returned when calling the function BSP_SD_GetStatus().
