How do I know status of the LMFC SYNC LOGIC into the datpath MUX?

See diagram below. On page 70 of the datasheet, it states that there is logic "FROM LMFC SYNC" that enables the data into the datapath. How do I know the value that goes in to the mux? Is there a register I read? A combination of registers? Is there somewhere in the datasheet that explains this but I have missed it?

 

I'm searching for reasons why my DAC is not outputting any RF even though it seems the part is correctly configured and I am transmitting data from the FPGA.
