  * @brief   FSMC Low Layer HAL module driver.

  *

  *          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

  *

  @verbatim

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

                        ##### 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
