| Description: |
| (RW) Number of empty (no contact) frames ignored before |
| acknowledging the end of activity (deactivating touch). |
| |
| When the last finger is removed from the device, it sends a |
| number of empty frames. By holding off on deactivation for a few |
| frames false erroneous disconnects can be tolerated, where the |
| sensor may mistakenly not detect a finger that is still present. |
