  ==============================================================================
                        ##### How to use this driver #####
  ==============================================================================
    [..]
    The FMPI2C HAL driver can be used as follows:

    (#) Declare a FMPI2C_HandleTypeDef handle structure, for example:
        FMPI2C_HandleTypeDef  hfmpi2c;

    (#)Initialize the FMPI2C low level resources by implementing the @ref HAL_FMPI2C_MspInit() API:
        (##) Enable the FMPI2Cx interface clock
        (##) FMPI2C pins configuration
            (+++) Enable the clock for the FMPI2C GPIOs
            (+++) Configure FMPI2C pins as alternate function open-drain
        (##) NVIC configuration if you need to use interrupt process
            (+++) Configure the FMPI2Cx interrupt priority
            (+++) Enable the NVIC FMPI2C IRQ Channel
        (##) DMA Configuration if you need to use DMA process
            (+++) Declare a DMA_HandleTypeDef handle structure for the transmit or receive stream
            (+++) Enable the DMAx interface clock using
            (+++) Configure the DMA handle parameters
            (+++) Configure the DMA Tx or Rx stream
            (+++) Associate the initialized DMA handle to the hfmpi2c DMA Tx or Rx handle
            (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on
                  the DMA Tx or Rx stream

    (#) Configure the Communication Clock Timing, Own Address1, Master Addressing mode, Dual Addressing mode,
        Own Address2, Own Address2 Mask, General call and Nostretch mode in the hfmpi2c Init structure.

    (#) Initialize the FMPI2C registers by calling the @ref HAL_FMPI2C_Init(), configures also the low level Hardware
        (GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_FMPI2C_MspInit(&hfmpi2c) API.

    (#) To check if target device is ready for communication, use the function @ref HAL_FMPI2C_IsDeviceReady()

    (#) For FMPI2C IO and IO MEM operations, three operation modes are available within this driver :

           This action will inform Master to generate a Stop condition to discard the communication.


    *** Interrupt mode or DMA mode IO sequential operation ***
    ==========================================================
    [..]
      (@) These interfaces allow to manage a sequential transfer with a repeated start condition
          when a direction change during transfer
    [..]
      (+) A specific option field manage the different steps of a sequential transfer
      (+) Option field values are defined through @ref FMPI2C_XFEROPTIONS and are listed below:
      (++) FMPI2C_FIRST_AND_LAST_FRAME: No sequential usage, functional is same as associated interfaces in no sequential mode
      (++) FMPI2C_FIRST_FRAME: Sequential usage, this option allow to manage a sequence with start condition, address
                            and data to transfer without a final stop condition
      (++) FMPI2C_FIRST_AND_NEXT_FRAME: Sequential usage (Master only), this option allow to manage a sequence with start condition, address
                            and data to transfer without a final stop condition, an then permit a call the same master sequential interface
                            several times (like @ref HAL_FMPI2C_Master_Seq_Transmit_IT() then @ref HAL_FMPI2C_Master_Seq_Transmit_IT()

                            if no direction change and without a final stop condition in both cases
      (++) FMPI2C_LAST_FRAME: Sequential usage, this option allow to manage a sequance with a restart condition, address
                            and with new data to transfer if the direction change or manage only the new data to transfer
                            if no direction change and with a final stop condition in both cases
      (++) FMPI2C_LAST_FRAME_NO_STOP: Sequential usage (Master only), this option allow to manage a restart condition after several call of the same master sequential
                            interface several times (link with option FMPI2C_FIRST_AND_NEXT_FRAME).
                            Usage can, transfer several bytes one by one using HAL_FMPI2C_Master_Seq_Transmit_IT(option FMPI2C_FIRST_AND_NEXT_FRAME then FMPI2C_NEXT_FRAME)

                            Then usage of this option FMPI2C_LAST_FRAME_NO_STOP at the last Transmit or Receive sequence permit to call the opposite interface Receive or Transmit
                              without stopping the communication and so generate a restart condition.
      (++) FMPI2C_OTHER_FRAME: Sequential usage (Master only), this option allow to manage a restart condition after each call of the same master sequential
                            interface.
                            Usage can, transfer several bytes one by one with a restart with slave address between each bytes using HAL_FMPI2C_Master_Seq_Transmit_IT(option FMPI2C_FIRST_FRAME then FMPI2C_OTHER_FRAME)

     *** FMPI2C HAL driver macros list ***
     ==================================
     [..]
       Below the list of most used macros in FMPI2C HAL driver.

      (+) @ref __HAL_FMPI2C_ENABLE: Enable the FMPI2C peripheral
      (+) @ref __HAL_FMPI2C_DISABLE: Disable the FMPI2C peripheral
      (+) @ref __HAL_FMPI2C_GENERATE_NACK: Generate a Non-Acknowledge FMPI2C peripheral in Slave mode
      (+) @ref __HAL_FMPI2C_GET_FLAG: Check whether the specified FMPI2C flag is set or not
      (+) @ref __HAL_FMPI2C_CLEAR_FLAG: Clear the specified FMPI2C pending flag
      (+) @ref __HAL_FMPI2C_ENABLE_IT: Enable the specified FMPI2C interrupt
      (+) @ref __HAL_FMPI2C_DISABLE_IT: Disable the specified FMPI2C interrupt

     *** Callback registration ***
     =============================================
    [..]
     The compilation flag USE_HAL_FMPI2C_REGISTER_CALLBACKS when set to 1
     allows the user to configure dynamically the driver callbacks.
     Use Functions @ref HAL_FMPI2C_RegisterCallback() or @ref HAL_FMPI2C_RegisterAddrCallback()
     to register an interrupt callback.
    [..]
     Function @ref HAL_FMPI2C_RegisterCallback() allows to register following callbacks:
       (+) MasterTxCpltCallback : callback for Master transmission end of transfer.
       (+) MasterRxCpltCallback : callback for Master reception end of transfer.
       (+) SlaveTxCpltCallback  : callback for Slave transmission end of transfer.
       (+) SlaveRxCpltCallback  : callback for Slave reception end of transfer.
       (+) ListenCpltCallback   : callback for end of listen mode.
       (+) MemTxCpltCallback    : callback for Memory transmission end of transfer.
       (+) MemRxCpltCallback    : callback for Memory reception end of transfer.
       (+) ErrorCallback        : callback for error detection.
       (+) AbortCpltCallback    : callback for abort completion process.
       (+) MspInitCallback      : callback for Msp Init.
       (+) MspDeInitCallback    : callback for Msp DeInit.
     This function takes as parameters the HAL peripheral handle, the Callback ID
     and a pointer to the user callback function.
    [..]
     For specific callback AddrCallback use dedicated register callbacks : @ref HAL_FMPI2C_RegisterAddrCallback().
    [..]
     Use function @ref HAL_FMPI2C_UnRegisterCallback to reset a callback to the default
     weak function.
     @ref HAL_FMPI2C_UnRegisterCallback takes as parameters the HAL peripheral handle,
     and the Callback ID.
     This function allows to reset following callbacks:
       (+) MasterTxCpltCallback : callback for Master transmission end of transfer.
       (+) MasterRxCpltCallback : callback for Master reception end of transfer.
       (+) SlaveTxCpltCallback  : callback for Slave transmission end of transfer.
       (+) SlaveRxCpltCallback  : callback for Slave reception end of transfer.
       (+) ListenCpltCallback   : callback for end of listen mode.
       (+) MemTxCpltCallback    : callback for Memory transmission end of transfer.
       (+) MemRxCpltCallback    : callback for Memory reception end of transfer.
       (+) ErrorCallback        : callback for error detection.
       (+) AbortCpltCallback    : callback for abort completion process.
       (+) MspInitCallback      : callback for Msp Init.
       (+) MspDeInitCallback    : callback for Msp DeInit.
    [..]
     For callback AddrCallback use dedicated register callbacks : @ref HAL_FMPI2C_UnRegisterAddrCallback().
    [..]
     By default, after the @ref HAL_FMPI2C_Init() and when the state is @ref HAL_FMPI2C_STATE_RESET
     all callbacks are set to the corresponding weak functions:
     examples @ref HAL_FMPI2C_MasterTxCpltCallback(), @ref HAL_FMPI2C_MasterRxCpltCallback().
     Exception done for MspInit and MspDeInit functions that are
     reset to the legacy weak functions in the @ref HAL_FMPI2C_Init()/ @ref HAL_FMPI2C_DeInit() only when
     these callbacks are null (not registered beforehand).
     If MspInit or MspDeInit are not null, the @ref HAL_FMPI2C_Init()/ @ref HAL_FMPI2C_DeInit()
     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
    [..]
     Callbacks can be registered/unregistered in @ref HAL_FMPI2C_STATE_READY state only.
     Exception done MspInit/MspDeInit functions that can be registered/unregistered
     in @ref HAL_FMPI2C_STATE_READY or @ref HAL_FMPI2C_STATE_RESET state,
     thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
     Then, the user first registers the MspInit/MspDeInit user callbacks
     using @ref HAL_FMPI2C_RegisterCallback() before calling @ref HAL_FMPI2C_DeInit()
     or @ref HAL_FMPI2C_Init() function.
    [..]
     When the compilation flag USE_HAL_FMPI2C_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.

          all related peripherals resources (CLOCK, GPIO, DMA, IT and NVIC ).

      (+) Call the function HAL_FMPI2C_Init() to configure the selected device with
          the selected configuration:
        (++) Clock Timing
        (++) Own Address 1
        (++) Addressing mode (Master, Slave)

        (++) Own Address 2
        (++) Own Address 2 Mask
        (++) General call mode

      (+) Call the function HAL_FMPI2C_DeInit() to restore the default configuration
          of the selected FMPI2Cx peripheral.

    [..]
    This subsection provides a set of functions allowing to manage the FMPI2C data
    transfers.

    (#) There are two modes of transfer:
       (++) Blocking mode : The communication is performed in the polling mode.
            The status of all data processing is returned by the same function
            after finishing transfer.
       (++) No-Blocking mode : The communication is performed using Interrupts
            or DMA. These functions return the status of the transfer startup.
            The end of the data processing will be indicated through the
            dedicated FMPI2C IRQ when using Interrupt mode or the DMA IRQ when
            using DMA mode.

    (#) Blocking mode functions are :
        (++) HAL_FMPI2C_Master_Transmit()
        (++) HAL_FMPI2C_Master_Receive()
        (++) HAL_FMPI2C_Slave_Transmit()

        (++) HAL_FMPI2C_Mem_Write()
        (++) HAL_FMPI2C_Mem_Read()
        (++) HAL_FMPI2C_IsDeviceReady()

    (#) No-Blocking mode functions with Interrupt are :
        (++) HAL_FMPI2C_Master_Transmit_IT()
        (++) HAL_FMPI2C_Master_Receive_IT()
        (++) HAL_FMPI2C_Slave_Transmit_IT()
        (++) HAL_FMPI2C_Slave_Receive_IT()
        (++) HAL_FMPI2C_Mem_Write_IT()
        (++) HAL_FMPI2C_Mem_Read_IT()
        (++) HAL_FMPI2C_Master_Seq_Transmit_IT()

        (++) HAL_FMPI2C_Slave_Seq_Transmit_IT()
        (++) HAL_FMPI2C_Slave_Seq_Receive_IT()
        (++) HAL_FMPI2C_EnableListen_IT()
        (++) HAL_FMPI2C_DisableListen_IT()
        (++) HAL_FMPI2C_Master_Abort_IT()

    (#) No-Blocking mode functions with DMA are :
        (++) HAL_FMPI2C_Master_Transmit_DMA()
        (++) HAL_FMPI2C_Master_Receive_DMA()
        (++) HAL_FMPI2C_Slave_Transmit_DMA()
        (++) HAL_FMPI2C_Slave_Receive_DMA()
        (++) HAL_FMPI2C_Mem_Write_DMA()
        (++) HAL_FMPI2C_Mem_Read_DMA()
        (++) HAL_FMPI2C_Master_Seq_Transmit_DMA()
        (++) HAL_FMPI2C_Master_Seq_Receive_DMA()
        (++) HAL_FMPI2C_Slave_Seq_Transmit_DMA()
        (++) HAL_FMPI2C_Slave_Seq_Receive_DMA()

    (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
        (++) HAL_FMPI2C_MasterTxCpltCallback()
        (++) HAL_FMPI2C_MasterRxCpltCallback()
        (++) HAL_FMPI2C_SlaveTxCpltCallback()
