0016 The KPP is designed to interface with a keypad matrix with 2-point contact
0017 or 3-point contact keys. The KPP is designed to simplify the software task
0018 of scanning a keypad matrix. The KPP is capable of detecting, debouncing,
0019 and decoding one or multiple keys pressed simultaneously on a keypad.
