  ==============================================================================
    [..]
      (#) Initialize the FDCAN peripheral using HAL_FDCAN_Init function.

      (#) If needed , configure the reception filters and optional features using
          the following configuration functions:
            (++) HAL_FDCAN_ConfigClockCalibration
            (++) HAL_FDCAN_ConfigFilter
            (++) HAL_FDCAN_ConfigGlobalFilter
            (++) HAL_FDCAN_ConfigExtendedIdMask
            (++) HAL_FDCAN_ConfigRxFifoOverwrite
            (++) HAL_FDCAN_ConfigFifoWatermark
            (++) HAL_FDCAN_ConfigRamWatchdog
            (++) HAL_FDCAN_ConfigTimestampCounter
            (++) HAL_FDCAN_EnableTimestampCounter
            (++) HAL_FDCAN_DisableTimestampCounter
            (++) HAL_FDCAN_ConfigTimeoutCounter
            (++) HAL_FDCAN_EnableTimeoutCounter
            (++) HAL_FDCAN_DisableTimeoutCounter
            (++) HAL_FDCAN_ConfigTxDelayCompensation
            (++) HAL_FDCAN_EnableTxDelayCompensation
            (++) HAL_FDCAN_DisableTxDelayCompensation
            (++) HAL_FDCAN_EnableISOMode
            (++) HAL_FDCAN_DisableISOMode
            (++) HAL_FDCAN_EnableEdgeFiltering
            (++) HAL_FDCAN_DisableEdgeFiltering
            (++) HAL_FDCAN_TT_ConfigOperation
            (++) HAL_FDCAN_TT_ConfigReferenceMessage
            (++) HAL_FDCAN_TT_ConfigTrigger

      (#) Start the FDCAN module using HAL_FDCAN_Start function. At this level
          the node is active on the bus: it can send and receive messages.

      (#) The following Tx control functions can only be called when the FDCAN
          module is started:
            (++) HAL_FDCAN_AddMessageToTxFifoQ
            (++) HAL_FDCAN_EnableTxBufferRequest
            (++) HAL_FDCAN_AbortTxRequest

      (#) After having submitted a Tx request in Tx Fifo or Queue, it is possible to
          get Tx buffer location used to place the Tx request thanks to
          HAL_FDCAN_GetLatestTxFifoQRequestBuffer API.
          It is then possible to abort later on the corresponding Tx Request using
          HAL_FDCAN_AbortTxRequest API.

      (#) When a message is received into the FDCAN message RAM, it can be
          retrieved using the HAL_FDCAN_GetRxMessage function.

      (#) Calling the HAL_FDCAN_Stop function stops the FDCAN module by entering
          it to initialization mode and re-enabling access to configuration
          registers through the configuration functions listed here above.

      (#) All other control functions can be called any time after initialization
          phase, no matter if the FDCAN module is started or stoped.

      *** Polling mode operation ***
      ==============================

    [..]
        (#) Reception and transmission states can be monitored via the following
            functions:
              (++) HAL_FDCAN_IsRxBufferMessageAvailable
              (++) HAL_FDCAN_IsTxBufferMessagePending
              (++) HAL_FDCAN_GetRxFifoFillLevel
              (++) HAL_FDCAN_GetTxFifoFreeLevel

      *** Interrupt mode operation ***
      ================================
      [..]
        (#) There are two interrupt lines: line 0 and 1.
            By default, all interrupts are assigned to line 0. Interrupt lines
            can be configured using HAL_FDCAN_ConfigInterruptLines function.

        (#) Notifications are activated using HAL_FDCAN_ActivateNotification
            function. Then, the process can be controlled through one of the
            available user callbacks: HAL_FDCAN_xxxCallback.

  *** Callback registration ***
  =============================================

  The compilation define USE_HAL_FDCAN_REGISTER_CALLBACKS when set to 1
  allows the user to configure dynamically the driver callbacks.
  Use Function @ref HAL_FDCAN_RegisterCallback() or HAL_FDCAN_RegisterXXXCallback()
  to register an interrupt callback.

  Function @ref HAL_FDCAN_RegisterCallback() allows to register following callbacks:
    (+) TxFifoEmptyCallback          : Tx Fifo Empty Callback.
    (+) RxBufferNewMessageCallback   : Rx Buffer New Message Callback.
    (+) HighPriorityMessageCallback  : High Priority Message Callback.
    (+) TimestampWraparoundCallback  : Timestamp Wraparound Callback.
    (+) TimeoutOccurredCallback      : Timeout Occurred Callback.
    (+) ErrorCallback                : Error Callback.
    (+) MspInitCallback              : FDCAN MspInit.
    (+) MspDeInitCallback            : FDCAN MspDeInit.
  This function takes as parameters the HAL peripheral handle, the Callback ID
  and a pointer to the user callback function.

  For specific callbacks ClockCalibrationCallback, TxEventFifoCallback, RxFifo0Callback, RxFifo1Callback,
  TxBufferCompleteCallback, TxBufferAbortCallback, ErrorStatusCallback, TT_ScheduleSyncCallback, TT_TimeMarkCallback,
  TT_StopWatchCallback and TT_GlobalTimeCallback, use dedicated register callbacks :
  respectively @ref HAL_FDCAN_RegisterClockCalibrationCallback(), @ref HAL_FDCAN_RegisterTxEventFifoCallback(),
  @ref HAL_FDCAN_RegisterRxFifo0Callback(), @ref HAL_FDCAN_RegisterRxFifo1Callback(),
  @ref HAL_FDCAN_RegisterTxBufferCompleCallback(), @ref HAL_FDCAN_RegisterTxBufferAbortCallback(),
  @ref HAL_FDCAN_RegisterErrorStatusCallback(), @ref HAL_FDCAN_TT_RegisterScheduleSyncCallback(),
  @ref HAL_FDCAN_TT_RegisterTimeMarkCallback(), @ref HAL_FDCAN_TT_RegisterStopWatchCallback() and
  @ref HAL_FDCAN_TT_RegisterGlobalTimeCallback().

  Use function @ref HAL_FDCAN_UnRegisterCallback() to reset a callback to the default
  weak function.
  @ref HAL_FDCAN_UnRegisterCallback takes as parameters the HAL peripheral handle,
  and the Callback ID.
  This function allows to reset following callbacks:
    (+) TxFifoEmptyCallback          : Tx Fifo Empty Callback.
    (+) RxBufferNewMessageCallback   : Rx Buffer New Message Callback.
    (+) HighPriorityMessageCallback  : High Priority Message Callback.
    (+) TimestampWraparoundCallback  : Timestamp Wraparound Callback.
    (+) TimeoutOccurredCallback      : Timeout Occurred Callback.
    (+) ErrorCallback                : Error Callback.
    (+) MspInitCallback              : FDCAN MspInit.
    (+) MspDeInitCallback            : FDCAN MspDeInit.

  For specific callbacks ClockCalibrationCallback, TxEventFifoCallback, RxFifo0Callback,
  RxFifo1Callback, TxBufferCompleteCallback, TxBufferAbortCallback, TT_ScheduleSyncCallback,
  TT_TimeMarkCallback, TT_StopWatchCallback and TT_GlobalTimeCallback, use dedicated
  register callbacks : respectively @ref HAL_FDCAN_UnRegisterClockCalibrationCallback(),
  @ref HAL_FDCAN_UnRegisterTxEventFifoCallback(), @ref HAL_FDCAN_UnRegisterRxFifo0Callback(),
  @ref HAL_FDCAN_UnRegisterRxFifo1Callback(), @ref HAL_FDCAN_UnRegisterTxBufferCompleCallback(),
  @ref HAL_FDCAN_UnRegisterTxBufferAbortCallback(), @ref HAL_FDCAN_UnRegisterErrorStatusCallback(),
  @ref HAL_FDCAN_TT_UnRegisterScheduleSyncCallback(), @ref HAL_FDCAN_TT_UnRegisterTimeMarkCallback(),
  @ref HAL_FDCAN_TT_UnRegisterStopWatchCallback() and @ref HAL_FDCAN_TT_UnRegisterGlobalTimeCallback().

  By default, after the @ref HAL_FDCAN_Init() and when the state is HAL_FDCAN_STATE_RESET,
  all callbacks are set to the corresponding weak functions:
  examples @ref HAL_FDCAN_ErrorCallback().
  Exception done for MspInit and MspDeInit functions that are
  reset to the legacy weak function in the @ref HAL_FDCAN_Init()/ @ref HAL_FDCAN_DeInit() only when
  these callbacks are null (not registered beforehand).
  if not, MspInit or MspDeInit are not null, the @ref HAL_FDCAN_Init()/ @ref HAL_FDCAN_DeInit()
  keep and use the user MspInit/MspDeInit callbacks (registered beforehand)

  Callbacks can be registered/unregistered in HAL_FDCAN_STATE_READY state only.
  Exception done MspInit/MspDeInit that can be registered/unregistered
  in HAL_FDCAN_STATE_READY or HAL_FDCAN_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_FDCAN_RegisterCallback() before calling @ref HAL_FDCAN_DeInit()
  or @ref HAL_FDCAN_Init() function.

  When The compilation define USE_HAL_FDCAN_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.
