Z-Axis Scaling
Z-axis scaling is typically not required as no Z data is available with resistive
touchscreens. The controller defaults to 0-255, but always returns the HighPoint
value.
Setting or Querying the Invert Axes Flags
Axes may be inverted by using these flags, or preferably, by swapping the
LowPoint and HighPoint scaling values.
IMask is a byte value where the least significant 3 bits specify which axes to invert
as follows:
Bit Axis
0 Invert X Axis
1 Invert Y Axis
2 Invert Z Axis
Scaling and Axis Inversion are disabled by factory default.
