Teensy 4.x H/W Quadrature Encoder Library

When doing this bridge between pin 0 and pin 2, should I add in any passive components, such as a diode or something to make sure there is no noise or reverse voltage going back to pin 0? or is this overkill?

Someone with more hardware knowledge will have to answer this one.

Know this is probably overkill but this might help. Let us know what you come up - I am interested as well
