I'm Japanese. I'm sorry for my poor English.

I'm evaluating ADV7800.

 

I adjust sample phase. (IO Map, 0x19, [4:0])

And I found that 0xCD and 0xCE in CP change according to sample phase. (IO Map, 0x19, [4:0])

by same source, same picture, same resolution.

 

I think that when sample phase matches with input analog RGB, the data will be small.

 

But there were no explanations of 0xCD and 0xCE in CP.

 

If I watched 0xCD and 0xCE in CP, could I detect phase gap in analog RGB input?

Are'nt phase gap and 0xCD and 0xCE in CP  relate?
