Initialization and Configuration functions.
===============================================================================
##### Initialization and de-initialization functions #####
===============================================================================
[..] This subsection provides a set of functions allowing to initialize and
de-initialize the SAIx peripheral:
(+) User must implement HAL_SAI_MspInit() function in which he configures
all related peripherals resources (CLOCK, GPIO, DMA, IT and NVIC ).
(+) Call the function HAL_SAI_Init() to configure the selected device with
the selected configuration:
(++) Mode (Master/slave TX/RX)
(++) Protocol
(++) Data Size
(++) MCLK Output
(++) Audio frequency
(++) FIFO Threshold
(++) Frame Config
(++) Slot Config
(+) Call the function HAL_SAI_DeInit() to restore the default configuration
of the selected SAI peripheral.
◆ HAL_SAI_DeInit()
