| description: | |
| 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. |
