If your Encoder can be pressed and there is a button inside, use the Input or Latching Input functionality mentioned above.
Encoders have 2 signals, which must be connected to 2 pins. There are three options.
Best Performance: Both signals connect to interrupt pins.
Good Performance: First signal connects to an interrupt pin, second to a non-interrupt pin.
Low Performance: Both signals connect to non-interrupt pins, details below.
