ADAU1442 Flexible TDM6 Configuration with ASRC

I am trying to get the following configuration to work, but failing.  Am I trying to do something impossible?

 

 

  • Serial I/O 0 : TDM6 - 6 channel - 16 bit per channel - (Flexible TDM Mode) ADAU1442 is slave.  clock slaved to external device
  • Serial I/O 1: Unused
  • Serial I/O 2: TDM2 - 24 bit per channel - ADAU1442 is the master at 48KHz
  • Serial I/O 3: TDM2 - 24 bit per channel - ADAU1442 is the master at 48KHz
  • Serial I/O 4: TDM2 - 24 bit per channel - ADAU1442 is the master at 48KHz
  • Serial I/O 5: TDM2 - 24 bit per channel - ADAU1442 is the master at 48KHz

 

1) Is it possible to have flexible TDM combined with ASRC?

2) Is it possible to have 16bit TDM6 as your flexible TDM?

 

If 1 and 2 are both possible, I would really appreciate a walkthrough for this configuration, similar to http://ez.analog.com/message/56822#56822, as I have been spinning my wheels for days on this issue.
