- * @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
