uint32_t SPI_InitTypeDef::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

Note:: The communication clock is derived from the master clock. The slave clock does not need to be set.
