I don't even remember if the C72 is a chip. Might have been a C74? To further complicate, iirc the C-series is customer specific version with limited data released on it.

ALTHOUGH Nexus is a trace interface, basically Ethernet 10G trimmed down to communicate to a micro directly. And there is pretty much no information on it outside the ultra expensive tools you need to buy.

EDIT: LOL downvotes for Nexus and an obscure STM chip :D Oh Hackernews... be less Reddit.
