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

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