626 This subsection provides a set of functions allowing to manage the I2S
627 data transfers.
628
629 [..] The I2S supports master and slave mode:
630
631 (#) There are two modes of transfer:
632 (++) Blocking mode: The communication is performed in polling mode.
633 The HAL status of all data processing is returned by the same function
634 after finishing transfer.
635 (++) No-Blocking mode: The communication is performed using Interrupts
636 or DMA, These APIs return the HAL status.
637 The end of the data processing will be indicated through the
638 dedicated I2S IRQ when using Interrupt mode or the DMA IRQ when
639 using DMA mode.
640 The hal_i2s_tx_cplt_callback(), hal_i2s_rx_cplt_callback() and hal_i2s_tx_rx_cplt_callback() user callbacks
641 will be executed respectively at the end of the transmit or Receive process
642 The hal_i2s_error_callback() user callback will be executed when a communication error is detected.
643
644 (#) APIs provided for these 2 transfer modes (Blocking mode or Non blocking mode using either Interrupt or DMA)
645 exist for 1-Line (simplex) and 2-Line (full duplex) modes.
