14Description:
15 (RW) Number of empty (no contact) frames ignored before
16 acknowledging the end of activity (deactivating touch).
17
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.
