Hi John,

the SPI module sends the SCLK clock to AD7714 and synchronizes this way the
transfer of 16-bit data. So you can use

unsigned char SPI(unsigned char TX_Data)
(
   SSPBUF = TX_Data; // start clock and send data
   while(BF == 0)    // wait until new data ready
         ;
   return(SSPBUF);   // return new 8-bit data
)

main()
{
   Data_1 = SPI(0xFF);
   Data_2 = SPI(0xFF);
}
