I'm having trouble seeing where the datasheet actually says the GPIO pins are 5V tolerant.

EDIT: okay, section 14.8.2.1 mentions two types of digital pins: "Standard Digital" and "Fault Tolerant Digital", and the FT Digital pins might be 5V tolerant, it looks like.



Page 13: "GPIOs are 5 V-tolerant (powered), and 3.3 V-failsafe (unpowered)"


Yep, I edited a few minutes ago to mention a reference I found in the datasheet. It's cool, but the reality seems a little more nuanced than that quote would indicate, since that only appears to work for GPIO-only pins, not just pins being used as GPIO. (So, if a pin supports analog input, for example, it will not be 5V tolerant.)
