* @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 | |

##### 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. | |
