Position of the touch in ratio engine sensors.
Movement of the touch location as a function of POS1 – POS0, where POS1 is current position
and POS0 is position before.
Delay between current and previous samples in unit of time.
Each bit is 8mS (if MAF is enabled), or 1/4mS (if MAF is not enabled).
0x84-0x86, 0x87-0x89

Position of the touch as calculation output of Ratio Engine 1 and 2 Data is organized
as a "packet" of 3 bytes. The data is backed by 4-level of buffer
