I have read some conflicting sources about what pins have internal pullup resistors available for the Attiny85 microcontroller. Can all I/O pins work with INPUT_PULLUP, or just some of them? And if so, which ones?
Thanks!

Check the datasheet, probably just search for "internal" or "pullup" enter image description here I believe there are little more pins/ports as portB, so they should all have internal pull ups.
