Description
===========
This format represents delta data from a touch controller.
Delta values may range from -128 to 127. Typically the values will vary through
a small range depending on whether the sensor is touched or not. The full value
may be seen if one of the touchscreen nodes has a fault or the line is not
connected.
**Byte Order.**
Each cell is one byte.
