What should ADAU1966 TDM16 waveform look like exactly??

I am trying to use TDM16 input mode on ADAU1966 and having no luck.

The datasheet does not give a complete waveform for what the device expects.  In fact, figure 15 seems to indicate it might even require 1 LRCLK pulse per slot (which make no sense at all).

Can someone please point me to a reference that shows the expected input waveform??

Specifically, I am trying to use TDM16 input with DLRCLK mode (internal PLL).  I also have an external BCLK available if needed, but would rather not use it.  Neither way works right now....
