587 This subsection provides a set of functions allowing to manage the I2S
588 data transfers.
589
590 [..] The I2S supports master and slave mode:
591
592 (#) There are two modes of transfer:
593 (++) Blocking mode: The communication is performed in polling mode.
594 The HAL status of all data processing is returned by the same function
595 after finishing transfer.
596 (++) No-Blocking mode: The communication is performed using Interrupts
597 or DMA, These APIs return the HAL status.
598 The end of the data processing will be indicated through the
599 dedicated I2S IRQ when using Interrupt mode or the DMA IRQ when
600 using DMA mode.
601 The hal_i2s_tx_cplt_callback(), hal_i2s_rx_cplt_callback() and hal_i2s_tx_rx_cplt_callback() user callbacks
602 will be executed respectively at the end of the transmit or Receive process
603 The hal_i2s_error_callback() user callback will be executed when a communication error is detected.
604
605 (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA)
606 exist for 1-Line (simplex) and 2-Line (full duplex) modes.
