Function Name
void I2S_Cmd ( SPI_TypeDef * SPIx, FunctionalState
NewState)
Function Description
Enables or disables the specified SPI peripheral (in I2S mode).
Parameters
 SPIx:To : select the SPIx peripheral, where x can be: 2 or 3
in I2S mode or I2Sxext for I2S full duplex mode.
 NewState : new state of the SPIx peripheral. This parameter
can be: ENABLE or DISABLE.
Return values
 None.
Notes
 None.
20.2.7.9 SPI_DataSizeConfig
Function Name
void SPI_DataSizeConfig ( SPI_TypeDef * SPIx, uint16_t
SPI_DataSize)
Function Description
Configures the data size for the selected SPI.
Parameters
 SPIx : where x can be 1, 2 or 3 to select the SPI peripheral.
 SPI_DataSize : specifies the SPI data size. For the SPIx
peripheral this parameter can be one of the following values:
 SPI_DataSize_4b : Set data size to 4 bits
 SPI_DataSize_5b : Set data size to 5 bits
 SPI_DataSize_6b : Set data size to 6 bits
 SPI_DataSize_7b : Set data size to 7 bits
 SPI_DataSize_8b : Set data size to 8 bits
 SPI_DataSize_9b : Set data size to 9 bits
 SPI_DataSize_10b : Set data size to 10 bits
 SPI_DataSize_11b : Set data size to 11 bits
 SPI_DataSize_12b : Set data size to 12 bits
 SPI_DataSize_13b : Set data size to 13 bits
 SPI_DataSize_14b : Set data size to 14 bits
 SPI_DataSize_15b : Set data size to 15 bits
 SPI_DataSize_16b : Set data size to 16 bits
Return values
 None.
Notes
 None.
