What do you recommend setting 0xDE of ADV7513 ?

Please give me answer.

In the ADV7513_programming_Guide Page 165

0xDE  R/W
[7:4] 0001**** Fixed Must be set to Default for proper operation

[3] ****0*** TMDS Clock Inversion TMDS Clock Inversion
   
0 = Normal TMDS Clock
1 = Inverted TMDS Clock

[2:1] *****000 Fixed Must be set to Default for proper operation


I think that best setting is 0x10 of 0xDE.

Is it true?

[7:4] 0001**** Fixed Must be set to Default for proper operation

[3]     ****0*** TMDS Clock Inversion TMDS Clock Inversion

 

Why is [7:4] bit changed?

And why is [3]bit changed? Why is TMDS Clock inverse?

Must TMDS Clock set Inversion?


Best regard.
