16-bit signed Touch Delta


Description
===========

This format represents delta data from a touch controller.

Delta values may range from -32768 to 32767. 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.
