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

    (#) Declare a SWPMI_HandleTypeDef handle structure (eg. SWPMI_HandleTypeDef hswpmi).

    (#) Initialize the SWPMI low level resources by implementing the HAL_SWPMI_MspInit() API:
        (##) Enable the SWPMIx interface clock with __HAL_RCC_SWPMIx_CLK_ENABLE().
        (##) SWPMI IO configuration:
            (+++) Enable the clock for the SWPMI GPIO.
            (+++) Configure these SWPMI pins as alternate function pull-up.
        (##) NVIC configuration if you need to use interrupt process (HAL_SWPMI_Transmit_IT()
             and HAL_SWPMI_Receive_IT() APIs):
            (+++) Configure the SWPMIx interrupt priority with HAL_NVIC_SetPriority().
            (+++) Enable the NVIC SWPMI IRQ handle with HAL_NVIC_EnableIRQ().

        (##) DMA Configuration if you need to use DMA process (HAL_SWPMI_Transmit_DMA()
             and HAL_SWPMI_Receive_DMA() APIs):
            (+++) Declare a DMA handle structure for the Tx/Rx streams.
            (+++) Enable the DMAx interface clock.
            (+++) Configure the declared DMA handle structure with the required
                  Tx/Rx parameters.
            (+++) Configure the DMA Tx/Rx streams and requests.
            (+++) Associate the initialized DMA handle to the SWPMI DMA Tx/Rx handle.
            (+++) Configure the priority and enable the NVIC for the transfer complete
                  interrupt on the DMA Tx/Rx streams.

    (#) Program the Bite Rate, Tx Buffering mode, Rx Buffering mode in the Init structure.

    (#) Enable the SWPMI peripheral by calling the HAL_SWPMI_Init() function.

  [..]
    Three operation modes are available within this driver :

    *** Polling mode IO operation ***
    =================================
    [..]
      (+) Send an amount of data in blocking mode using HAL_SWPMI_Transmit()
      (+) Receive an amount of data in blocking mode using HAL_SWPMI_Receive()

    *** Interrupt mode IO operation ***
    ===================================
    [..]
      (+) Send an amount of data in non-blocking mode using HAL_SWPMI_Transmit_IT()
      (+) At transmission end of transfer HAL_SWPMI_TxCpltCallback() is executed and user can
          add his own code by customization of function pointer HAL_SWPMI_TxCpltCallback()

      (+) In case of flag error, HAL_SWPMI_ErrorCallback() function is executed and user can
          add his own code by customization of function pointer HAL_SWPMI_ErrorCallback()

    *** DMA mode IO operation ***
    =============================
    [..]
      (+) Send an amount of data in non-blocking mode (DMA) using HAL_SWPMI_Transmit_DMA()
      (+) At transmission end of transfer HAL_SWPMI_TxCpltCallback() is executed and user can
          add his own code by customization of function pointer HAL_SWPMI_TxCpltCallback()
      (+) Receive an amount of data in non-blocking mode (DMA) using HAL_SWPMI_Receive_DMA()
      (+) At reception end of transfer HAL_SWPMI_RxCpltCallback() is executed and user can
          add his own code by customization of function pointer HAL_SWPMI_RxCpltCallback()
      (+) In case of flag error, HAL_SWPMI_ErrorCallback() function is executed and user can
          add his own code by customization of function pointer HAL_SWPMI_ErrorCallback()
      (+) Stop the DMA Transfer using HAL_SWPMI_DMAStop()

    *** SWPMI HAL driver additional function list ***
    ===============================================
    [..]
      Below the list the others API available SWPMI HAL driver :

      (+) HAL_SWPMI_EnableLoopback(): Enable the loopback mode for test purpose only
      (+) HAL_SWPMI_DisableLoopback(): Disable the loopback mode

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

      (+) __HAL_SWPMI_ENABLE(): Enable the SWPMI peripheral
      (+) __HAL_SWPMI_DISABLE(): Disable the SWPMI peripheral
      (+) __HAL_SWPMI_TRANSCEIVER_ENABLE(): Enable the SWPMI peripheral transceiver
      (+) __HAL_SWPMI_TRANSCEIVER_DISABLE(): Disable the SWPMI peripheral transceiver
      (+) __HAL_SWPMI_ENABLE_IT(): Enable the specified SWPMI interrupts
      (+) __HAL_SWPMI_DISABLE_IT(): Disable the specified SWPMI interrupts
      (+) __HAL_SWPMI_GET_IT_SOURCE(): Check if the specified SWPMI interrupt source is
          enabled or disabled
      (+) __HAL_SWPMI_GET_FLAG(): Check whether the specified SWPMI flag is set or not

    *** Callback registration ***
    =============================
    [..]
      The compilation define USE_HAL_SWPMI_REGISTER_CALLBACKS when set to 1
      allows the user to configure dynamically the driver callbacks.
    [..]
      Use function HAL_SWPMI_RegisterCallback() to register a user callback. It allows
      to register the following callbacks:
      (+) RxCpltCallback     : SWPMI receive complete.
      (+) RxHalfCpltCallback : SWPMI receive half complete.
      (+) TxCpltCallback     : SWPMI transmit complete.
      (+) TxHalfCpltCallback : SWPMI transmit half complete.
      (+) ErrorCallback      : SWPMI error.
      (+) MspInitCallback    : SWPMI MspInit.
      (+) MspDeInitCallback  : SWPMI MspDeInit.
    [..]
    This function takes as parameters the HAL peripheral handle, the callback ID
    and a pointer to the user callback function.
    [..]
    Use function HAL_SWPMI_UnRegisterCallback() to reset a callback to the default
    weak (surcharged) function.
    HAL_SWPMI_UnRegisterCallback() takes as parameters the HAL peripheral handle,
    and the callback ID.
    This function allows to reset following callbacks:
      (+) RxCpltCallback     : SWPMI receive complete.
      (+) RxHalfCpltCallback : SWPMI receive half complete.
      (+) TxCpltCallback     : SWPMI transmit complete.
      (+) TxHalfCpltCallback : SWPMI transmit half complete.
      (+) ErrorCallback      : SWPMI error.
      (+) MspInitCallback    : SWPMI MspInit.
      (+) MspDeInitCallback  : SWPMI MspDeInit.
    [..]
    By default, after the HAL_SWPMI_Init and if the state is HAL_SWPMI_STATE_RESET
    all callbacks are reset to the corresponding legacy weak (surcharged) functions:
    examples HAL_SWPMI_RxCpltCallback(), HAL_SWPMI_ErrorCallback().
    Exception done for MspInit and MspDeInit callbacks that are respectively
    reset to the legacy weak (surcharged) functions in the HAL_SWPMI_Init
    and HAL_SWPMI_DeInit only when these callbacks are null (not registered beforehand).
    If not, MspInit or MspDeInit are not null, the HAL_SWPMI_Init and HAL_SWPMI_DeInit
    keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
    [..]
    Callbacks can be registered/unregistered in READY state only.
    Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
    in READY or 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 HAL_SWPMI_RegisterCallback before calling @ref HAL_SWPMI_DeInit
    or HAL_SWPMI_Init function.
    [..]
    When the compilation define USE_HAL_SWPMI_REGISTER_CALLBACKS is set to 0 or
    not defined, the callback registering feature is not available
    and weak (surcharged) callbacks are used.

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

    (#) There are two modes of transfer:
       (++) Blocking mode: The communication is performed in polling mode.
            The HAL status of all data processing is returned by the same function
            after finishing transfer.
       (++) Non-Blocking mode: The communication is performed using Interrupts
           or DMA. The end of the data processing will be indicated through the
           dedicated SWPMI Interrupt handler (HAL_SWPMI_IRQHandler()) when using Interrupt mode or
           the selected DMA stream interrupt handler when using DMA mode.
           The HAL_SWPMI_TxCpltCallback(), HAL_SWPMI_RxCpltCallback() user callbacks
           will be executed respectively at the end of the transmit or receive process.
           The HAL_SWPMI_ErrorCallback() user callback will be executed when a communication error is detected.

    (#) Blocking mode API's are:
        (++) HAL_SWPMI_Transmit()
        (++) HAL_SWPMI_Receive()

    (#) Non-Blocking mode API's with Interrupt are:
        (++) HAL_SWPMI_Transmit_IT()
        (++) HAL_SWPMI_Receive_IT()
        (++) HAL_SWPMI_IRQHandler()

    (#) Non-Blocking mode API's with DMA are:
        (++) HAL_SWPMI_Transmit_DMA()
        (++) HAL_SWPMI_Receive_DMA()
        (++) HAL_SWPMI_DMAPause()
        (++) HAL_SWPMI_DMAResume()
        (++) HAL_SWPMI_DMAStop()

    (#) A set of Transfer Complete Callbacks are provided in Non-Blocking mode:
        (++) HAL_SWPMI_TxHalfCpltCallback()
        (++) HAL_SWPMI_TxCpltCallback()
        (++) HAL_SWPMI_RxHalfCpltCallback()
        (++) HAL_SWPMI_RxCpltCallback()
        (++) HAL_SWPMI_ErrorCallback()

    (#) The capability to launch the above IO operations in loopback mode for
        user application verification:
        (++) HAL_SWPMI_EnableLoopback()
        (++) HAL_SWPMI_DisableLoopback()
