/** ****************************************************************************** * @file stm32f4xx_ll_fsmc.c * @author MCD Application Team * @version V1.5.2 * @date 22-September-2016 * @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. @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2016 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
