| * @brief FMC Low Layer HAL module driver. |
| * |
| * This file provides firmware functions to manage the following |
| * functionalities of the Flexible Memory Controller (FMC) peripheral memories: |
| * + Initialization/de-initialization functions |
| * + Peripheral Control functions |
| * + Peripheral State functions |
| * |
| @verbatim |
| ============================================================================== |
| ##### FMC peripheral features ##### |
| ============================================================================== |
| [..] The Flexible memory controller (FMC) includes following memory controllers: |
| (+) The NOR/PSRAM memory controller |
| (+) The NAND/PC Card memory controller |
| |
| [..] The FMC 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 FMC performs |
| only one access at a time to an external device. |
| The main features of the FMC 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 |
