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

    (#) Declare a PSSI_HandleTypeDef handle structure, for example:
        PSSI_HandleTypeDef  hpssi;

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

    (#) Configure the Communication Bus Width,  Control Signals, Input Polarity and Output Polarity
         in the hpssi Init structure.

    (#) Initialize the PSSI registers by calling the @ref HAL_PSSI_Init(), configure also the low level Hardware
        (GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_PSSI_MspInit(&hpssi) API.

    (#) For PSSI IO operations, two operation modes are available within this driver :

    *** Polling mode IO operation ***
    =================================
    [..]
      (+) Transmit an amount of data by byte in blocking mode using @ref HAL_PSSI_Transmit()
      (+) Receive an amount of data by byte in blocking mode using @ref HAL_PSSI_Receive()

    *** DMA mode IO operation ***
    ==============================
    [..]
      (+) Transmit an amount of data in non-blocking mode (DMA) using
          @ref HAL_PSSI_Transmit_DMA()
      (+) At transmission end of transfer, @ref HAL_PSSI_TxCpltCallback() is executed and user can
           add his own code by customization of function pointer @ref HAL_PSSI_TxCpltCallback()
      (+) Receive an amount of data in non-blocking mode (DMA) using
          @ref HAL_PSSI_Receive_DMA()
      (+) At reception end of transfer, @ref HAL_PSSI_RxCpltCallback() is executed and user can
           add his own code by customization of function pointer @ref HAL_PSSI_RxCpltCallback()
      (+) In case of transfer Error, @ref HAL_PSSI_ErrorCallback() function is executed and user can
           add his own code by customization of function pointer @ref HAL_PSSI_ErrorCallback()
      (+) Abort a  PSSI process communication with Interrupt using @ref HAL_PSSI_Abort_IT()
      (+) End of abort process, @ref HAL_PSSI_AbortCpltCallback() is executed and user can
           add his own code by customization of function pointer @ref HAL_PSSI_AbortCpltCallback()

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

      (+) @ref HAL_PSSI_ENABLE     : Enable the PSSI peripheral
      (+) @ref HAL_PSSI_DISABLE    : Disable the PSSI peripheral
      (+) @ref HAL_PSSI_GET_FLAG   : Check whether the specified PSSI flag is set or not
      (+) @ref HAL_PSSI_CLEAR_FLAG : Clear the specified PSSI pending flag
      (+) @ref HAL_PSSI_ENABLE_IT  : Enable the specified PSSI interrupt
      (+) @ref HAL_PSSI_DISABLE_IT : Disable the specified PSSI interrupt

     *** Callback registration ***
     =============================================
     Use Functions @ref HAL_PSSI_RegisterCallback() or @ref HAL_PSSI_RegisterAddrCallback()
     to register an interrupt callback.

     Function @ref HAL_PSSI_RegisterCallback() allows to register following callbacks:
       (+) TxCpltCallback       : callback for transmission end of transfer.
       (+) RxCpltCallback       : callback for 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.


     Use function @ref HAL_PSSI_UnRegisterCallback to reset a callback to the default
     weak function.
     @ref HAL_PSSI_UnRegisterCallback takes as parameters the HAL peripheral handle,
     and the Callback ID.
     This function allows to reset following callbacks:
       (+) TxCpltCallback       : callback for transmission end of transfer.
       (+) RxCpltCallback       : callback for 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.


     By default, after the @ref HAL_PSSI_Init() and when the state is @ref HAL_PSSI_STATE_RESET
     all callbacks are set to the corresponding weak functions:
     examples @ref HAL_PSSI_TxCpltCallback(), @ref HAL_PSSI_RxCpltCallback().
     Exception done for MspInit and MspDeInit functions that are
     reset to the legacy weak functions in the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit() only when
     these callbacks are null (not registered beforehand).
     If MspInit or MspDeInit are not null, the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit()
     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.

     Callbacks can be registered/unregistered in @ref HAL_PSSI_STATE_READY state only.
     Exception done MspInit/MspDeInit functions that can be registered/unregistered
     in @ref HAL_PSSI_STATE_READY or @ref HAL_PSSI_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_PSSI_RegisterCallback() before calling @ref HAL_PSSI_DeInit()
     or @ref HAL_PSSI_Init() function.

    [..]
    This subsection provides a set of functions allowing to manage the PSSI 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 DMA.
            These functions return the status of the transfer startup.
            The end of the data processing will be indicated through the
            dedicated  the DMA IRQ .

    (#) Blocking mode functions are :
        (++) HAL_PSSI_Transmit()
        (++) HAL_PSSI_Receive()

    (#) No-Blocking mode functions with DMA are :
        (++) HAL_PSSI_Transmit_DMA()
        (++) HAL_PSSI_Receive_DMA()

    (#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
        (++) HAL_PSSI_TxCpltCallback()
        (++) HAL_PSSI_RxCpltCallback()
        (++) HAL_PSSI_ErrorCallback()
        (++) HAL_PSSI_AbortCpltCallback()
