                     ##### How to use this driver #####
  ==============================================================================  
  [..] 
   (#) This driver is used to drive the IS61WV102416BLL-10M SRAM external memory mounted
       on STM32L476G-EVAL evaluation board.

   (#) This driver does not need a specific component driver for the SRAM device
       to be included with.

   (#) Initialization steps:
       (++) Initialize the SRAM external memory using the BSP_SRAM_Init() function. This 
            function includes the MSP layer hardware resources initialization and the
            FMC controller configuration to interface with the external SRAM memory.
  
   (#) SRAM read/write operations
       (++) SRAM external memory can be accessed with read/write operations once it is
            initialized.
            Read/write operation can be performed with AHB access using the functions
            BSP_SRAM_ReadData()/BSP_SRAM_WriteData(), or by DMA transfer using the functions
            BSP_SRAM_ReadData_DMA()/BSP_SRAM_WriteData_DMA().
       (++) The AHB access is performed with 16-bit width transaction, the DMA transfer
            configuration is fixed at single (no burst) halfword transfer 
            (see the SRAM_MspInit() static function).
       (++) User can implement his own functions for read/write access with his desired 
            configurations.
       (++) If interrupt mode is used for DMA transfer, the function BSP_SRAM_DMA_IRQHandler()
            is called in IRQ handler file, to serve the generated interrupt once the DMA 
            transfer is complete.
