[ADV7611] How to output no Hsync/Vsync signals from the pin in the BT.656 (Embedded Sync) 8bit output mode.

I have a question about ADV7611.


When we use ADV7611 as BT.656 (Embedded Sync) 8bit output mode, the IC which receives the 8bit BT.656 does not have to get the Hsync/Vsync from the HS pin/VS pin of the ADV7611.
Even if I set the registers of ADV7611 as the 8bit BT.656 (Embedded Sync) mode (OP_FORMAT_SEL[7:0] = 0x00, 8-bit SDR ITU-656 mode), I can see the Hsync/Vsync signals from the HS pin/VS pin of the ADV7611.


 Is there a method or register setting that ADV7611 does not output the Hsync/Vsync signals from HS/VS pin in the   BT.656 (Embedded Sync) 8bit output mode?
 Is this possible?


If this is possible, it's useful for debugging our customer's board. I'll try it.


Thank you!
Best regards.
