UCD90160 - Reading from memory

Other Parts Discussed in Thread: UCD90160

I'm working on our test procedure to test a board with the UCD90160 component, and I'm trying to figure out if there is a way to interrogate this component about what program is loaded in it?

 

I have a connection to this component via the PMBus, and am trying to find commands to talk to it. I have not had any luck finding documentation about supported commands...can you help?

 

Would there be any commands to toggle the GPO, read the MON status or any other commands that could improve test coverage of this component?
