ADV7611 Free Run Mode

Hi,

Is there any way to program a custom free run pixel clock frequency, HS width, VS width, front porch, back porch... other than the format dictated by the PRIM_MODE[3:0] and VID_STD[5:0] settings?

I have the ADV7611 outputs connect to 800x480 display. I want to display some known color when there is no input signal. The prefered PCLK is 33.26 MHZ. The HS ~ 128 PCLKs. The VS ~ 5 Lines. The front and back porch are also programmable. I couldn't find any of this infomation in the UG-180. Please help. Thanks
