Calib2<7:6>: not implemented, read as '0'
TRIM_TEMP<5:0>: defines the calibration settings of the temperature sensor
The offset of the temperature curve is measured at one temperature (preferably 30deg. C) and permanently stored in the
zenerzap OTP with 6 bit word length.
This information is accessible via the Calib2 register, see Table 23.
