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.
