TPS65982: Is there a way i can read a particular register and confirm that TPS65982 has been negotiated for any of the PDO?

I am using TPS65982 in my design, and my system requirement is that, i need to read status from TPS65982 and check if the 15V or 20V PDO has been contracted, based on this i need to take some decision in the system.

Which register will tell me whether the 15V/20V profile is negotiated.
