| 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. |
