Notifying that a Touch Switch Has Been Pressed
When “On” is set for “Bit In” when setting the screen attribute with the support tool,
the “touch switch pressed” status is sent to the Host in the bit information.
If “Off” is set for “Bit In”, the address corresponding to the touch switch is sent to the
Host in a 3-digit hexadecimal value when the touch switch is pressed.
The commands used for this report are described below.
