    Answer:

    Leaving unused input pins open may cause permanent damage from a malfunction or latch-up. Take measures for unused pins such as pulling up or pulling down the voltage with resistors of 2 kilo ohms or higher.

    If there are any unused input/output pins, set them to the output state and then open them, or set them to the input state and handle them in the same way as input pins.
