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

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:

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?
