Self-Power Down Mode – The self-power down mode is enabled by default. The option is used
to conserve power. If disabled, the TSC will always be on and will consume more power.
External Filter – The external filter is enabled by default. When enabled, the touch panel data
is first sent through the external filter before an A/D conversion is done. This option should be
used in noisy environments.
Calibration Tab
The driver supports five point calibration only. When a calibration is done, the driver will show
the raw A/D value of the calibration points that are stored in the TSC.
The Refresh button will cause the driver to retrieve the stored calibration data on the TSC to
refresh the display.
The Calibrate button will cause the driver to use the stored calibration data on the TSC to align
the mouse pointer with the touch on the panel.
