Data Fields
uint32_t	BaudRate	Specifies the BaudRate prescaler value which will be used to configure the transmit and receive SCK clock. This parameter can be a value of Baud Rate Prescaler. Note The communication clock is derived from the master clock. The slave clock does not need to be set. This feature can be modified afterwards using unitary function LL_SPI_SetBaudRatePrescaler().
uint32_t	BitOrder	Specifies whether data transfers start from MSB or LSB bit. This parameter can be a value of Transmission Bit Order. This feature can be modified afterwards using unitary function LL_SPI_SetTransferBitOrder().
uint32_t	ClockPhase	Specifies the clock active edge for the bit capture. This parameter can be a value of Clock Phase. This feature can be modified afterwards using unitary function LL_SPI_SetClockPhase().
uint32_t	ClockPolarity	Specifies the serial clock steady state. This parameter can be a value of Clock Polarity. This feature can be modified afterwards using unitary function LL_SPI_SetClockPolarity().
uint32_t	CRCCalculation	Specifies if the CRC calculation is enabled or not. This parameter can be a value of CRC Calculation. This feature can be modified afterwards using unitary functions LL_SPI_EnableCRC() and LL_SPI_DisableCRC().
uint32_t	CRCPoly	Specifies the polynomial used for the CRC calculation. This parameter must be a number between Min_Data = 0x00 and Max_Data = 0xFFFF. This feature can be modified afterwards using unitary function LL_SPI_SetCRCPolynomial().
uint32_t	DataWidth	Specifies the SPI data width. This parameter can be a value of Datawidth. This feature can be modified afterwards using unitary function LL_SPI_SetDataWidth().
uint32_t	Mode	Specifies the SPI mode (Master/Slave). This parameter can be a value of Operation Mode. This feature can be modified afterwards using unitary function LL_SPI_SetMode().
uint32_t	NSS	Specifies whether the NSS signal is managed by hardware (NSS pin) or by software using the SSI bit. This parameter can be a value of Slave Select Pin Mode. This feature can be modified afterwards using unitary function LL_SPI_SetNSSMode().
uint32_t	TransferDirection	Specifies the SPI unidirectional or bidirectional data mode. This parameter can be a value of Transfer Mode. This feature can be modified afterwards using unitary function LL_SPI_SetTransferDirection().
