In normal operation, the AR1100 automatically returns
‘touch reports’ in response to a touch – no ‘prompting’
is required from the host. The following command set
can be used to configure the parameters used to
‘fine-tune’ the operation. To prevent touch reports from
interfering with these commands, it is recommended
that TOUCH_DISABLE be executed prior to any other
command(s) and the TOUCH_ENABLE command be
used as the last step to return the AR1100 to normal
operation.
