+ * 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
