* @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 two memory controllers:
(+) The NOR/PSRAM memory controller
(+) The NAND/PC Card memory controller
[..] The FSMC functional block makes the interface with synchronous and asynchronous static
memories, SDRAM 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).
(++) Read-only memory (ROM).
(++) NOR Flash memory/OneNAND 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.
