## Detailed Description

Data transfers functions.

      ==============================================================================
                          ##### IO operation functions #####
     ===============================================================================
     [..]
        This subsection provides a set of functions allowing to manage the QSPI
        data transfers.

        [..] The QSPI supports master and slave mode:

        (#) 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.
           (++) No-Blocking mode: The communication is performed using Interrupts.
                or DMA, These APIs return the HAL status.
                The end of the data processing will be indicated through the
                dedicated QSPI IRQ when using Interrupt mode or the DMA IRQ when
                using DMA mode.
                The hal_qspi_tx_cplt_callback(), hal_qspi_rx_cplt_callback() and hal_qspi_txrx_cplt_callback() user callbacks
                will be executed respectively at the end of the transmit or Receive process.
                The hal_qspi_error_callback() user callback will be executed when a communication error is detected

        (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA)
            exist for 1 Line (simplex) and 2 Lines (full duplex) modes.
