    + The KPP is designed to interface with a keypad matrix with 2-point contact
    + or 3-point contact keys. The KPP is designed to simplify the software task
    + of scanning a keypad matrix. The KPP is capable of detecting, debouncing,
    + and decoding one or multiple keys pressed simultaneously on a keypad.
