Does the code modification also add/modify what happen to the adjacent "offending" input pins?!?
Or you've been lucky OR...well... let's apply this rule
Sometimes, you don't wanna know why... and stay happy
Keep it simple... Look forward

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Re: Weird problem with logic level on pin.
Have you looked at the transitions with a scope?
Is there any undershoot?
The non-filtered version would be more likely to catch short lived pulses just under the threshold.

Re: Weird problem with logic level on pin.
No I have not scoped it but it's got to be something like that. I'm just a bit surprised that it "never" (that I know of) missed it before and now it didn't see it at all. I spent quite some time staring at the code before I even bothered to put the meter on it since I "was sure" that the hardware was OK.
I'll scope it next time I work on that project.
Thanks!
