ADV7180 Force Free run without having had any valid video input

Have a customer board with 7180 on it.  I don't have connector cable to get analog video input.  I would like to force ADV7180 into NTSC (J is fine) mode with free running output (i.e. force blue screen).  

It should just need

Set reg 0x0 to 0x40

Set reg 0xC to 0x37 (or 0x35)

I am in 656 mode and verified on another board if valid video is input then these registers settings work.  So my main question is for a test mode like this what other registers do I need to modify?

Thank you
