The host can selectively disable touch reporting from touchkeys that do not correspond to touch
targets by programming a touchkey type to be "dead." This simplifies touch report decoding for
the host because the TCS does not generate any touch reports from dead touchkeys.
However, if the Touchkey Type command is incorrectly sent with the dead parameter, especially
if it is applied to the entire touch panel, touch reporting may appear to be defective or Touch
Lockout Mode may seem to be set because no touch reports occur. If it is suspected that the TCS
is not generating touch reports due to dead touchkeys (rather than the other common touch-
related problems described in this appendix), the host could do any of the following steps. They
are listed in order of minimal loss of data or programming:
•
Use the Touchkey Type command to set all touchkey types to auto-repeat (the default type).
•
Use the Initialize Screen command to reinitialize the Displayed Screen.
•
Issue a Soft Reset command.
