I have floating GPIOs pins on a UCD90160 design.
If I do not set these IO in the pin assignments - what does the IC do with that pin?
Is there a weak pullup/down internally that gets set? Or should I set them in the GUI to something (i.e. output) and assign no logic to them? Is it safe to leave them floating?
I know the datasheet recommends to GND these pins but we did not do that to existing HW.
FYI - design is working fine with them floating and not enabled, but I have to close an action item so I prefer someone points to the reference in the documentation (if possible)
