        [..]
        This subsection provides a set of functions allowing to control the XQSPI.
         (+) hal_xqspi_get_state()API can be helpful to check in run-time the state of the XQSPI peripheral.
         (+) hal_xqspi_get_error() check in run-time Errors occurring during communication.
         (+) hal_xqspi_set_retry() set the repeat times during internal process.
         (+) hal_xqspi_set_tx_fifo_threshold() set the TX FIFO Threshold.
         (+) hal_xqspi_set_rx_fifo_threshold() set the RX FIFO Threshold.
         (+) hal_xqspi_get_tx_fifo_threshold() get the TX FIFO Threshold.
         (+) hal_xqspi_get_rx_fifo_threshold() get the RX FIFO Threshold.
