Sensor Status:
Each register hoIds 4 sensor status coded with 4 bits per status, so that together they build
one 16bit number. The sequence defined in the table above is to understand as from most
significant half byte to least significant half byte. Most of the sensors have two status values,
one for the sensor itself and the current measurement value, another one for the buffer, from
which average, min. And max values are evaluated.
