Afaik the internal pull-up/-down resistors aren't strong enough to stay outside of the problematic input voltage range and external ≤ 8kΩ resistors to 3.3V aren't acceptable unless you don't care about power consumption and your signal is still usable like that. It's a really annoying problem to have. I'm still waiting for a hardware revision that fixes the source of the problem instead of nasty workarounds. |
