The bit level description for temperature data from TEMP_MSB and TEMP_LSB registers is
presented in Table 10. Temperature data is presented in unsigned format. The LSB bit (bit B5 or t0
in Table 10) weight is ~0.56°C. See section 2.6 for more detailed information of converting the data
to temperature in [°C].
