What to do with unused H7 USB power pins?

RMcCa · ‎2019-10-20

I am laying a board for the first time with a an STM32H745ZIT and I'm wondering how I should connect the 2 unused USB power supply pins? I can't find anything in the data sheets, but I'm guessing I can leave them unconnected or maybe ground the input pin?

Thanks.

AN4938 wasn't specific either

In that these pins aren't available on the LQFP100 package, I would assume they can safely be left unconnected. But hopefully an ST employee will confirm this.
