SCR[7:0]  
SPI0 Clock Rate.  
These bits determine the frequency of the SCK output when the SPI0 module is  
configured for master mode operation. The SCK clock frequency is a divided ver-  
sion of the system clock, and is given in the following equation, where SYSCLK is  
the system clock frequency and SPI0CKR is the 8-bit value held in the SPI0CKR  
register.  
SYSCLK  
fSCK = ----------------------------------------------------------  
2  SPI0CKR[7:0] + 1

Example: If SYSCLK = 2 MHz and SPI0CKR = 0x04,  
2000000  
fSCK = -------------------------

fSCK = 200kHz

7:0 SPI0DAT[7:0] SPI0 Transmit and Receive Data.  
Function  
The SPI0DAT register is used to transmit and receive SPI0 data. Writing data to  
SPI0DAT places the data into the transmit buffer and initiates a transfer when in  
Master Mode. A read of SPI0DAT returns the contents of the receive buffer.
