  ==============================================================================
                          ##### How to use this driver #####
  ==============================================================================  
  [..]
    This driver is a generic layered driver which contains a set of APIs used to 
    control SRAM memories. It uses the FMC layer functions to interface 
    with SRAM devices.  
    The following sequence should be followed to configure the FMC to interface
    with SRAM/PSRAM memories: 
      
   (#) Declare a SRAM_HandleTypeDef handle structure, for example:
          SRAM_HandleTypeDef  hsram; and: 
          
       (++) Fill the SRAM_HandleTypeDef handle "Init" field with the allowed 
            values of the structure member.
            
       (++) Fill the SRAM_HandleTypeDef handle "Instance" field with a predefined 
            base register instance for NOR or SRAM device 
                         
       (++) Fill the SRAM_HandleTypeDef handle "Extended" field with a predefined
            base register instance for NOR or SRAM extended mode 
             
   (#) Declare two FMC_NORSRAM_TimingTypeDef structures, for both normal and extended 
       mode timings; for example:
          FMC_NORSRAM_TimingTypeDef  Timing and FMC_NORSRAM_TimingTypeDef  ExTiming;
      and fill its fields with the allowed values of the structure member.
      
   (#) Initialize the SRAM Controller by calling the function HAL_SRAM_Init(). This function
       performs the following sequence:
          
       (##) MSP hardware layer configuration using the function HAL_SRAM_MspInit()
       (##) Control register configuration using the FMC NORSRAM interface function 
            FMC_NORSRAM_Init()
       (##) Timing register configuration using the FMC NORSRAM interface function 
            FMC_NORSRAM_Timing_Init()
       (##) Extended mode Timing register configuration using the FMC NORSRAM interface function 
            FMC_NORSRAM_Extended_Timing_Init()
       (##) Enable the SRAM device using the macro __FMC_NORSRAM_ENABLE()    

   (#) At this stage you can perform read/write accesses from/to the memory connected 
       to the NOR/SRAM Bank. You can perform either polling or DMA transfer using the
       following APIs:
       (++) HAL_SRAM_Read()/HAL_SRAM_Write() for polling read/write access
       (++) HAL_SRAM_Read_DMA()/HAL_SRAM_Write_DMA() for DMA read/write transfer
       
   (#) You can also control the SRAM device by calling the control APIs HAL_SRAM_WriteOperation_Enable()/
       HAL_SRAM_WriteOperation_Disable() to respectively enable/disable the SRAM write operation  
       
   (#) You can continuously monitor the SRAM device HAL state by calling the function
       HAL_SRAM_GetState()
