Regarding simultaenous operation mode of ADV7604

Hi,

 

We are using ADV7604 and we are providing input using DVI-I connector on which at a time RGB (DVI-A) data or HDMI (DVI-D) signals can be available. We don't this in prior that which signals are going to come.

 

We wants to configure ADV7604 in such a way that it can detect both of the signals and do the auto-detection of provided input signal e.g. height, width, front porch, back porch...

 

Is there any possibility to have such intelligent configuration on ADV7604? I went through the data sheet and it appears that it can be configured only either of following modes,

 

PRIM_MODE[3:0] R/W

Selects the primary mode of operation of the decoder. To be used with VID_STD[5:0].

0000 - Reserved

0001 - Component Video (YPbPr/RGB)

0010 - RGB Graphics mode

0011 - Reserved

0100 - Reserved

0101 - HDMI-Comp

0110 - HDMI-GR

0111 - 1111 - Reserved

 

Thanks,

Ronak
