16
  The KPP is designed to interface with a keypad matrix with 2-point contact

17
  or 3-point contact keys. The KPP is designed to simplify the software task

18
  of scanning a keypad matrix. The KPP is capable of detecting, debouncing,

19
  and decoding one or multiple keys pressed simultaneously on a keypad.
