/** ****************************************************************************** * @file stm32f4xx_hal_nor.c * @author MCD Application Team * @version V1.2.0 * @date 26-December-2014 * @brief NOR HAL module driver. * This file provides a generic firmware to drive NOR memories mounted * as external device. * @verbatim ============================================================================== ##### How to use this driver ##### ============================================================================== [..] This driver is a generic layered driver which contains a set of APIs used to control NOR flash memories. It uses the FMC/FSMC layer functions to interface with NOR devices. This driver is used as follows: (+) NOR flash memory configuration sequence using the function HAL_NOR_Init() with control and timing parameters for both normal and extended mode. (+) Read NOR flash memory manufacturer code and device IDs using the function HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef structure declared by the function caller. (+) Access NOR flash memory by read/write data unit operations using the functions HAL_NOR_Read(), HAL_NOR_Program(). (+) Perform NOR flash erase block/chip operations using the functions HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip(). (+) Read the NOR flash CFI (common flash interface) IDs using the function HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef structure declared by the function caller. (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/ HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation (+) You can monitor the NOR device HAL state by calling the function HAL_NOR_GetState() [..] (@) This driver is a set of generic APIs which handle standard NOR flash operations. If a NOR flash device contains different operations and/or implementations, it should be implemented separately. *** NOR HAL driver macros list *** ============================================= [..] Below the list of most used macros in NOR HAL driver. (+) NOR_WRITE : NOR memory write data to specified address @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2014 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.
