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.
