Initialization and Configuration functions.
===============================================================================
##### Initialization and Configuration functions #####
===============================================================================
[..] This section provides a set of functions allowing to initialize the SPI Direction,
SPI Mode, SPI Data Size, SPI Polarity, SPI Phase, SPI NSS Management, SPI Baud
Rate Prescaler, SPI First Bit and SPI CRC Polynomial.
[..] The SPI_Init() function follows the SPI configuration procedures for Master mode
and Slave mode (details for these procedures are available in reference manual).
[..] When the Software NSS management (SPI_InitStruct->SPI_NSS = SPI_NSS_Soft) is selected,
use the following function to manage the NSS bit:
void SPI_NSSInternalSoftwareConfig(SPI_TypeDef* SPIx, uint16_t SPI_NSSInternalSoft);
[..] In Master mode, when the Hardware NSS management (SPI_InitStruct->SPI_NSS = SPI_NSS_Hard)
is selected, use the follwoing function to enable the NSS output feature.
void SPI_SSOutputCmd(SPI_TypeDef* SPIx, FunctionalState NewState);
[..] The NSS pulse mode can be managed by the SPI TI mode when enabling it using the following function:
void SPI_TIModeCmd(SPI_TypeDef* SPIx, FunctionalState NewState);
And it can be managed by software in the SPI Motorola mode using this function:
void SPI_NSSPulseModeCmd(SPI_TypeDef* SPIx, FunctionalState NewState);
[..] This section provides also functions to initialize the I2S Mode, Standard,
Data Format, MCLK Output, Audio frequency and Polarity.
[..] The I2S_Init() function follows the I2S configuration procedures for Master mode
and Slave mode.

Enables or disables the specified SPI peripheral (in I2S mode).
- Parameters
-
