Hi, Darren. 
 The evaluation software emulates the SPI protocol through the use of the SPORT. The evaluation board's communication line is designed physically to connect to the SPORT pins of the EVAL-SDP-CB1Z. 
 
 As you have mentioned you are using the EVAL-SDP-CS1Z. The SDP that you are using only have SPI, I2C/TWI, and GPIOs. It does not use SPORT. 
 
 As indicated in the last paragraph on the first page of the UG-459 : 
 
 This evaluation board requires the EVAL-SDP-CB1Z board (SDP-B controller board), which is available for order on the Analog Devices website at www.analog.com. 
 
 You would be able to use the evaluation board if you would use the EVAL-SDP-CB1Z .
