Memory Map and Registers Description
4.2.3.6 Y coordinate stabilization time
This 16-bit value holds the number needed in micro-seconds for the signals required for a Y coordinate scanning to stabilize.
The value is calculated automatically as part of the calibration process but can be written through serial communication to
simplify factory configuration of devices.

4.2.3.7 Z coordinate stabilization time
This 16-bit value holds the number needed in micro-seconds for the signals required for the pressure coordinate scanning to
stabilize. The value is calculated automatically as part of the calibration process, but can be written through serial
communication to simplify factory configuration of devices.

4.2.3.8 Display horizontal resolution
Determines the resolution for the X coordinates. It is important to configure this value properly before a calibration is executed.
Values written to this register have no effect until after both horizontal and vertical resolutions have been written. Writes to these
registers reset the device calibration.
