Checking for vblank on the ADV7623

All,

 

I assume I need to check for vblank before updating OSD tboxes because we occasionally get flicker in the text when updating (once per second.)  Does anyone know what register we check to see if we are in vblank?  I can just pull for the info so I don't need to use an interrupt if that helps.

 

I just can't find it in the docs.

 

Thank you!
