ADV7511 embedd sync register settings for different video rates

I am working on a project that uses ADV7511 to support many different incoming video rates.

   

It has proven that the rates supported by separate sync (0x15[3:0] = 0001) are working.

   

Now that I need to support other rates with embedded sync (0x15[3:0] = 0010).

 

I am able to use register 0x30 ~ 0x3A, with embedded sync to support 720p@60Hz, which is supported by separate sync, so I know embedded sync should work for me.

   

I found this file [ bt656-ADV7842_7511-hdmi.txt ] on the forum, but it does not satisfy my need.

   

I need register settings for other rates, for example: NTSC@59.94Hz, PAL@50Hz, 720p@24/25/29.97/30/50/59.94/60Hz, 1035i@50/59.94/60Hz... and other more popular rates.

   

My question is: is there info out there that I can use set up register 0x30 ~ 0x3A for these rates, just like those in [ bt656-ADV7842_7511-hdmi.txt ]

   

Thanks for any help.
