| * @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. |
