where can I get timing diagram, data structure and operational info on the Connect ME 9210 SPI port?

I am trying to interface it to an FPGA but I am not having any luck finding info in the SPI other then pinout.

NS9210 HRM here:  
[http://ftp1.digi.com/support/documentation/90000846\_K.pdf](http://ftp1.digi.com/support/documentation/90000846_K.pdf)  
has hardware infprmation about SPI.  
timing should match standard SPI specification. Are you able to see SPI transactions on a scope? What seems to be the problem?
