+                        ##### How to use this driver #####
+ ===============================================================================
+    [..]
+    The MDIOS HAL driver can be used as follow:
+
+    (#) Declare a MDIOS_HandleTypeDef handle structure.
+
+    (#) Initialize the MDIOS low level resources by implementing the HAL_MDIOS_MspInit() API:
+        (##) Enable the MDIOS interface clock.
+        (##) MDIOS pins configuration:
+            (+++) Enable clocks for the MDIOS GPIOs.
+            (+++) Configure the MDIOS pins as alternate function.
+        (##) NVIC configuration if you need to use interrupt process:
+            (+++) Configure the MDIOS interrupt priority.
+            (+++) Enable the NVIC MDIOS IRQ handle.
+
+    (#) Program the Port Address and the Preamble Check in the Init structure.
+
+    (#) Initialize the MDIOS registers by calling the HAL_MDIOS_Init() API.
+
+    (#) Perform direct slave read/write operations using the following APIs:
+        (##) Read the value of a DINn register: HAL_MDIOS_ReadReg()
+        (##) Write a value to a DOUTn register: HAL_MDIOS_WriteReg()
+
+    (#) Get the Master read/write operations flags using the following APIs:
+        (##) Bit map of DOUTn registers read by Master: HAL_MDIOS_GetReadRegAddress()
+        (##) Bit map of DINn registers written by Master : HAL_MDIOS_GetWrittenRegAddress()
+
+    (#) Clear the read/write flags using the following APIs:
+        (##) Clear read flags of a set of registers: HAL_MDIOS_ClearReadRegAddress()
+        (##) Clear write flags of a set of registers: HAL_MDIOS_ClearWriteRegAddress()
+
+    (#) Enable interrupts on events using HAL_MDIOS_EnableEvents(), when called
+        the MDIOS will generate an interrupt in the following cases:
+        (##) a DINn register written by the Master
+        (##) a DOUTn register read by the Master
+        (##) an error occur
+
+        (@) A callback is executed for each genereted interrupt, so the driver provide the following
+            HAL_MDIOS_WriteCpltCallback(), HAL_MDIOS_ReadCpltCallback() and HAL_MDIOS_ErrorCallback()
+        (@) HAL_MDIOS_IRQHandler() must be called from the MDIOS IRQ Handler, to handle the interrupt
+            and execute the previous callbacks
+
+    (#) Reset the MDIOS peripheral and all related ressources by calling the HAL_MDIOS_DeInit() API.
+        (##) HAL_MDIOS_MspDeInit() must be implemented to reset low level ressources
+            (GPIO, Clocks, NVIC configuration ...)
+
+  *** Callback registration ***
+  =============================================
+
+  The compilation define  USE_HAL_MDIOS_REGISTER_CALLBACKS when set to 1
+  allows the user to configure dynamically the driver callbacks.
+  Use Function @ref HAL_MDIOS_RegisterCallback() to register an interrupt callback.
+
+  Function @ref HAL_MDIOS_RegisterCallback() allows to register following callbacks:
+    (+) WriteCpltCallback  : Write Complete Callback.
+    (+) ReadCpltCallback   : Read Complete Callback.
+    (+) ErrorCallback      : Error Callback.
+    (+) WakeUpCallback     : Wake UP Callback
+    (+) MspInitCallback    : MspInit Callback.
+    (+) MspDeInitCallback  : MspDeInit Callback.
+
+  This function takes as parameters the HAL peripheral handle, the Callback ID
+  and a pointer to the user callback function.
+
+  Use function @ref HAL_MDIOS_UnRegisterCallback() to reset a callback to the default
+  weak function.
+  @ref HAL_MDIOS_UnRegisterCallback takes as parameters the HAL peripheral handle,
+  and the Callback ID.
+  This function allows to reset following callbacks:
+    (+) WriteCpltCallback  : Write Complete Callback.
+    (+) ReadCpltCallback   : Read Complete Callback.
+    (+) ErrorCallback      : Error Callback.
+    (+) WakeUpCallback     : Wake UP Callback
+    (+) MspInitCallback    : MspInit Callback.
+    (+) MspDeInitCallback  : MspDeInit Callback.
+
+  By default, after the HAL_MDIOS_Init and when the state is HAL_MDIOS_STATE_RESET
+  all callbacks are set to the corresponding weak functions:
+  examples @ref HAL_MDIOS_WriteCpltCallback(), @ref HAL_MDIOS_ReadCpltCallback().
+  Exception done for MspInit and MspDeInit functions that are
+  reset to the legacy weak function in the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit only when
+  these callbacks are null (not registered beforehand).
+  if not, MspInit or MspDeInit are not null, the HAL_MDIOS_Init/ @ref HAL_MDIOS_DeInit
+  keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+  Callbacks can be registered/unregistered in HAL_MDIOS_STATE_READY state only.
+  Exception done MspInit/MspDeInit that can be registered/unregistered
+  in HAL_MDIOS_STATE_READY or HAL_MDIOS_STATE_RESET state,
+  thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+  In that case first register the MspInit/MspDeInit user callbacks
+  using @ref HAL_MDIOS_RegisterCallback() before calling @ref HAL_MDIOS_DeInit
+  or HAL_MDIOS_Init function.
+
+  When The compilation define USE_HAL_MDIOS_REGISTER_CALLBACKS is set to 0 or
+  not defined, the callback registration feature is not available and all callbacks
+  are set to the corresponding weak functions.
