405/584
 Specifies the clock active edge for the bit capture. This parameter can be a value
of SPI_Clock_Phase
 uint16_t SPI_InitTypeDef::SPI_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
SPI_Slave_Select_management
 uint16_t SPI_InitTypeDef::SPI_BaudRatePrescaler
 Specifies the Baud Rate prescaler value which will be used to configure the
transmit and receive SCK clock. This parameter can be a value of
SPI_BaudRate_Prescaler.
 uint16_t SPI_InitTypeDef::SPI_FirstBit
 Specifies whether data transfers start from MSB or LSB bit. This parameter can
be a value of SPI_MSB_LSB_transmission
 uint16_t SPI_InitTypeDef::SPI_CRCPolynomial
 Specifies the polynomial used for the CRC calculation.
