Hi !

 

I want to ask about Limited Range.

I want to see the data limit changes by changing OP_656_RANGE.res.JPG

I used the "6-1e Port A, 720p,1080i Any Color Space In (YCrCb 444 24bit from ADV761x) Through HDMI Out 444 YCrCb VIC[4,5,19,20]:"

And changed OP_656_Range.

I proved Data15 to Data0(16bits).

 

At OP_656_RANGE = 1'b1 "limited"

At OP_656_RANGE = 1'b0 "Full"

The resister setting and the waveform look like the opposite.

I checked read the resister and checked I confirmed that I was set surely.

Also I input few types of the picture and checked that the prove point is correct.

 

Is the Software manual is wrong or something wrong about my Eval-Board or tool or something?

Or my measuring is wrong?

 

Best regards.

Kawa
