  *          functionalities of the Flexible Static Memory Controller (FSMC) peripheral memories:

  =============================================================================
                        ##### FSMC peripheral features #####
  =============================================================================
    [..] The Flexible static memory controller (FSMC) includes following memory controllers:
         (+) The NOR/PSRAM memory controller
         (+) The PC Card memory controller
         (+) The NAND memory controller
             (PC Card and NAND controllers available only on STM32F101xE, STM32F103xE, STM32F101xG and STM32F103xG)

    [..] The FSMC functional block makes the interface with synchronous and asynchronous static
         memories and 16-bit PC memory cards. Its main purposes are:
         (+) to translate AHB transactions into the appropriate external device protocol.
         (+) to meet the access time requirements of the external memory devices.

    [..] All external memories share the addresses, data and control signals with the controller.
         Each external device is accessed by means of a unique Chip Select. The FSMC performs
         only one access at a time to an external device.
         The main features of the FSMC controller are the following:
          (+) Interface with static-memory mapped devices including:
             (++) Static random access memory (SRAM).
             (++) NOR Flash memory.
             (++) PSRAM (4 memory banks).
             (++) 16-bit PC Card compatible devices
             (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
                data
          (+) Independent Chip Select control for each memory bank
          (+) Independent configuration for each memory bank

  ==============================================================================

  [..]
    This driver contains a set of APIs to interface with the FSMC NORSRAM banks in order
    to run the NORSRAM external devices.

    (+) FSMC NORSRAM bank reset using the function FSMC_NORSRAM_DeInit()
    (+) FSMC NORSRAM bank control configuration using the function FSMC_NORSRAM_Init()
    (+) FSMC NORSRAM bank timing configuration using the function FSMC_NORSRAM_Timing_Init()
    (+) FSMC NORSRAM bank extended timing configuration using the function
        FSMC_NORSRAM_Extended_Timing_Init()
    (+) FSMC NORSRAM bank enable/disable write operation using the functions
        FSMC_NORSRAM_WriteOperation_Enable()/FSMC_NORSRAM_WriteOperation_Disable()
