Position: Last position of the touch on the slider
A change in this byte will cause the CHANGE line to trigger.
GPIO1...3: If GPIO1...3 are set as inputs, returns the logic level on the respective pin. If a GPIO
is set as an output, the respective bit in GPIO Read will always report “0".
GPIOs set as inputs are only read once every cycle, i.e. every 16ms.
A change in this byte will cause the CHANGE line to trigger.
This is an 8-bit sub-revision number that follows the code version (e.g. 4.0.0).
Writing any nonzero value into this address will trigger the QT2160 to start a recalibration on all
enabled keys.
