5 * @brief FSMC Low Layer HAL module driver.
6 *
7 * This file provides firmware functions to manage the following
8 * functionalities of the Flexible Static Memory Controller (FSMC) peripheral memories:
9 * + Initialization/de-initialization functions
10 * + Peripheral Control functions
11 * + Peripheral State functions
12 *
13 @verbatim
14 ==============================================================================
15 ##### FSMC peripheral features #####
16 ==============================================================================
17 [..] The Flexible static memory controller (FSMC) includes two memory controllers:
18 (+) The NOR/PSRAM memory controller
19 (+) The NAND/PC Card memory controller
20
21 [..] The FSMC functional block makes the interface with synchronous and asynchronous static
22 memories, SDRAM memories, and 16-bit PC memory cards. Its main purposes are:
23 (+) to translate AHB transactions into the appropriate external device protocol.
24 (+) to meet the access time requirements of the external memory devices.
25
26 [..] All external memories share the addresses, data and control signals with the controller.
27 Each external device is accessed by means of a unique Chip Select. The FSMC performs
28 only one access at a time to an external device.
29 The main features of the FSMC controller are the following:
30 (+) Interface with static-memory mapped devices including:
31 (++) Static random access memory (SRAM).
32 (++) Read-only memory (ROM).
33 (++) NOR Flash memory/OneNAND Flash memory.
34 (++) PSRAM (4 memory banks).
35 (++) 16-bit PC Card compatible devices.
36 (++) Two banks of NAND Flash memory with ECC hardware to check up to 8 Kbytes of
37 data.
38 (+) Independent Chip Select control for each memory bank.
39 (+) Independent configuration for each memory bank.
