| 15 | (RW) Number of empty (no contact) frames ignored before |
| 16 | acknowledging the end of activity (deactivating touch). |

| 18 | When the last finger is removed from the device, it sends a |
| 19 | number of empty frames. By holding off on deactivation for a few |
| 20 | frames false erroneous disconnects can be tolerated, where the |
| 21 | sensor may mistakenly not detect a finger that is still present. |
