Bits7–0: SCR7–SCR0: SPI Clock Rate
These bits determine the frequency of the SCK output when the SPI module is configured for master

mode operation. The SCK clock frequency is a divided down version of the system clock,
and is given in the following equations:
fSCK = 0.5 x fSYSCLK / (SPI0CKR + 1), for 0 < SPI0CKR < 255,
The SPI0DAT register is used to transmit and receive SPI data. Writing data to SPI0DAT
places the data immediately into the shift register and initiates a transfer when in Master
Mode. A read of SPI0DAT returns the contents of the receive buffer.
