  22.                      ##### How to use this driver #####
  23.   ==============================================================================
  24.     [..]
  25.       This driver is a generic layered driver which contains a set of APIs used to
  26.       control NOR flash memories. It uses the FSMC layer functions to interface
  27.       with NOR devices. This driver is used as follows:
  28.  
  29.       (+) NOR flash memory configuration sequence using the function HAL_NOR_Init()
  30.           with control and timing parameters for both normal and extended mode.
  31.  
  32.       (+) Read NOR flash memory manufacturer code and device IDs using the function
  33.           HAL_NOR_Read_ID(). The read information is stored in the NOR_ID_TypeDef
  34.           structure declared by the function caller.
  35.  
  36.       (+) Access NOR flash memory by read/write data unit operations using the functions
  37.           HAL_NOR_Read(), HAL_NOR_Program().
  38.  
  39.       (+) Perform NOR flash erase block/chip operations using the functions
  40.           HAL_NOR_Erase_Block() and HAL_NOR_Erase_Chip().
  41.  
  42.       (+) Read the NOR flash CFI (common flash interface) IDs using the function
  43.           HAL_NOR_Read_CFI(). The read information is stored in the NOR_CFI_TypeDef
  44.           structure declared by the function caller.
  45.  
  46.       (+) You can also control the NOR device by calling the control APIs HAL_NOR_WriteOperation_Enable()/
  47.           HAL_NOR_WriteOperation_Disable() to respectively enable/disable the NOR write operation
  48.  
  49.       (+) You can monitor the NOR device HAL state by calling the function
  50.           HAL_NOR_GetState()
  51.     [..]
  52.      (@) This driver is a set of generic APIs which handle standard NOR flash operations.
  53.          If a NOR flash device contains different operations and/or implementations,
  54.          it should be implemented separately.
  55.  
  56.      *** NOR HAL driver macros list ***
  57.      =============================================
  58.      [..]
  59.        Below the list of most used macros in NOR HAL driver.
  60.  
  61.       (+) NOR_WRITE : NOR memory write data to specified address
  62.  
  63.     *** Callback registration ***
  64.     =============================================
  65.     [..]
  66.       The compilation define  USE_HAL_NOR_REGISTER_CALLBACKS when set to 1
  67.       allows the user to configure dynamically the driver callbacks.
  68.  
  69.       Use Functions HAL_NOR_RegisterCallback() to register a user callback,
  70.       it allows to register following callbacks:
  71.         (+) MspInitCallback    : NOR MspInit.
  72.         (+) MspDeInitCallback  : NOR MspDeInit.
  73.       This function takes as parameters the HAL peripheral handle, the Callback ID
  74.       and a pointer to the user callback function.
  75.  
  76.       Use function HAL_NOR_UnRegisterCallback() to reset a callback to the default
  77.       weak (overridden) function. It allows to reset following callbacks:
  78.         (+) MspInitCallback    : NOR MspInit.
  79.         (+) MspDeInitCallback  : NOR MspDeInit.
  80.       This function) takes as parameters the HAL peripheral handle and the Callback ID.
  81.  
  82.       By default, after the HAL_NOR_Init and if the state is HAL_NOR_STATE_RESET
  83.       all callbacks are reset to the corresponding legacy weak (overridden) functions.
  84.       Exception done for MspInit and MspDeInit callbacks that are respectively
  85.       reset to the legacy weak (overridden) functions in the HAL_NOR_Init
  86.       and  HAL_NOR_DeInit only when these callbacks are null (not registered beforehand).
  87.       If not, MspInit or MspDeInit are not null, the HAL_NOR_Init and HAL_NOR_DeInit
  88.       keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
  89.  
  90.       Callbacks can be registered/unregistered in READY state only.
  91.       Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
  92.       in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
  93.       during the Init/DeInit.
  94.       In that case first register the MspInit/MspDeInit user callbacks
  95.       using HAL_NOR_RegisterCallback before calling HAL_NOR_DeInit
  96.       or HAL_NOR_Init function.
  97.  
  98.       When The compilation define USE_HAL_NOR_REGISTER_CALLBACKS is set to 0 or
  99.       not defined, the callback registering feature is not available
  100.       and weak (overridden) callbacks are used.
