TPS65982: GPIO event for EN pin of HD3SS460

Hi Team,

My customer considers to use TPS65982 with HD3SS460 for DP alternate mode application.
I am studying which GPIO event should be assigned for EN pin of HD3SS460.

I believe either ATTACHED_H(PLUG_EVENT ) or DP_OR_USB3_H can be assigned.

Is my understanding correct?
if the answer is yes, which event is recommended?

Best Regards,
Yaita
