6 (RW) Number of contact frames ignored before acknowledging the
7 start of activity (activating touch).

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.
