    Question:

    What is the side effect when the input cut off function is not released?

     

    Answer:

    The initial setting of the GPORTEN register, which is related to the input cut off function is "disable input". Even if it is not released, the external signal input such as a port input or an external interrupt cannot be transmitted to the internal circuit. Therefore, the disable input must be released for detecting an external signal.
