  21.  ===============================================================================
  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 PCCARD/compact flash memories. It uses the FSMC layer functions
  27.      to interface with PCCARD devices. This driver is used for:
  28.  
  29.     (+) PCCARD/Compact Flash memory configuration sequence using the function
  30.         HAL_PCCARD_Init()/HAL_CF_Init() with control and timing parameters for
  31.         both common and attribute spaces.
  32.  
  33.     (+) Read PCCARD/Compact Flash memory maker and device IDs using the function
  34.         HAL_PCCARD_Read_ID()/HAL_CF_Read_ID(). The read information is stored in
  35.         the CompactFlash_ID structure declared by the function caller.
  36.  
  37.     (+) Access PCCARD/Compact Flash memory by read/write operations using the functions
  38.         HAL_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() -
  39.         HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
  40.  
  41.     (+) Perform PCCARD/Compact Flash Reset chip operation using the function
  42.         HAL_PCCARD_Reset()/HAL_CF_Reset.
  43.  
  44.     (+) Perform PCCARD/Compact Flash erase sector operation using the function
  45.         HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector.
  46.  
  47.     (+) Read the PCCARD/Compact Flash status operation using the function
  48.         HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus().
  49.  
  50.     (+) You can monitor the PCCARD/Compact Flash  device HAL state by calling
  51.         the function HAL_PCCARD_GetState()/HAL_CF_GetState()
  52.  
  53.    [..]
  54.      (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
  55.          operations. If a PCCARD/Compact Flash device contains different operations
  56.          and/or implementations, it should be implemented separately.
  57.  
  58.       *** Callback registration ***
  59.     =============================================
  60.     [..]
  61.       The compilation define  USE_HAL_PCCARD_REGISTER_CALLBACKS when set to 1
  62.       allows the user to configure dynamically the driver callbacks.
  63.  
  64.       Use Functions HAL_PCCARD_RegisterCallback() to register a user callback,
  65.       it allows to register following callbacks:
  66.         (+) MspInitCallback    : PCCARD MspInit.
  67.         (+) MspDeInitCallback  : PCCARD MspDeInit.
  68.       This function takes as parameters the HAL peripheral handle, the Callback ID
  69.       and a pointer to the user callback function.
  70.  
  71.       Use function HAL_PCCARD_UnRegisterCallback() to reset a callback to the default
  72.       weak (surcharged) function. It allows to reset following callbacks:
  73.         (+) MspInitCallback    : PCCARD MspInit.
  74.         (+) MspDeInitCallback  : PCCARD MspDeInit.
  75.       This function) takes as parameters the HAL peripheral handle and the Callback ID.
  76.  
  77.       By default, after the HAL_PCCARD_Init and if the state is HAL_PCCARD_STATE_RESET
  78.       all callbacks are reset to the corresponding legacy weak (surcharged) functions.
  79.       Exception done for MspInit and MspDeInit callbacks that are respectively
  80.       reset to the legacy weak (surcharged) functions in the HAL_PCCARD_Init
  81.       and  HAL_PCCARD_DeInit only when these callbacks are null (not registered beforehand).
  82.       If not, MspInit or MspDeInit are not null, the HAL_PCCARD_Init and HAL_PCCARD_DeInit
  83.       keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
  84.  
  85.       Callbacks can be registered/unregistered in READY state only.
  86.       Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
  87.       in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
  88.       during the Init/DeInit.
  89.       In that case first register the MspInit/MspDeInit user callbacks
  90.       using HAL_PCCARD_RegisterCallback before calling HAL_PCCARD_DeInit
  91.       or HAL_PCCARD_Init function.
  92.  
  93.       When The compilation define USE_HAL_PCCARD_REGISTER_CALLBACKS is set to 0 or
  94.       not defined, the callback registering feature is not available
  95.       and weak (surcharged) callbacks are used.
