Unused 3.3V VIO pins
I am REALLY boxed into a corner on a controller design using the P2. I cant increase the size of the board as it is a hard limit, and I cant stack anything. I’ve spent the day on my 4th reroute and came to the realization that there are several groups of pins that are unneeded. Can I get by without having to supply 3.3V power to these unused groups? If 3.3Visnt needed, do I have to ground them or can I float them (preferred, saves traces and space)?
