5.2.1.THERMOMETER AND TEMPERATURE VALUE
The function of the Thermometer is controlled by “ThP” and “ThE” (bit 0 & bit 1 in the register EEPROM Control).

The measured temperature value is stored in the register “Temperature” at address 20h.
The measured temperature is binary coded ranging from -60°C (=0d) to +190°C (=250d).
Example: Temperature of 0°C corresponding to a content of = 60d.
The thermometer has a resolution of 1°C per LSB; the typical accuracy is +/-4°C within the temperature range
-40°C to +125°C. The Thermometer is automatically disabled if status bit “Vlow1” is set = “1”, the result of the last
temperature measurement is frozen in register “Temperature” and the frequency compensation continues working
with this last temperature reading.
The actual temperature value can be read from register “Temperature” at address 20h. The Thermometer has to be
disabled by ThE = “0” to externally write a temperature value into the register “Temperature” at address 20h.
