  *          This file provides firmware functions to manage the following
  *          functionalities of the Flexible Static Memory Controller (FSMC) peripheral memories:
  *           + Initialization/de-initialization functions
  *           + Peripheral Control functions
  *           + Peripheral State functions

  =============================================================================
                        ##### 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.
