Data transfers functions.

 ===============================================================================
    [..]
    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()
