Trying to get analog RGB acticated

[spikespiegel]

I'm trying to activate the analog rgb video signal from the IC TDA9381, but I don't know how to do that. When I checked the datasheet, this is what I found:



This looks like data from the microcontroller, but I don't how to edit this.

This is the TV IC's datasheet:

This is the IC:


Pins 46, 47 and 48 are for the analog RGB, Pin 45 (INSSW2) is the fast blanking line.

I need some guidance, cause I not even have any idea as to where to start from.

This is from a CRT TV, I didn't buy its controller yet, but maybe this could be achieved from the Service Menu?
