[Function]
S When the status of a touch switch changes because it has been touched or re-
leased, notifies the change of status to the host.
S Normally, one command notifies the change in status of one allocated bit only,
but when multiple bits in the same word change simultaneously, those changes
are all notified together with one command.
Reference:
When the screen is switched after pressing a “momentary” key, this command
goes OFF. The change is also notified to the host.
