TPD12S520: TPD12S520:HPD with pull-up registor

Part Number: TPD12S520

Dear support team;

There is the following schematic in datasheet.

I designed by same schematic,Soc detected always HPD.

Becase there are pull-up registors with HDP line.(red circle)

Could you tell me why these registors need?

Best Regards,
