7.3.1 Digital Temperature Output

The digital output from each temperature measurement conversion is stored in the read-only temperature register. Which is a 12-bit, read-only register that stores the output of the most recent conversion. Two bytes must be read to obtain data. However, only the first 12 MSBs are used to indicate temperature while the remaining 4 LSB are set to zero. Table 7-1 lists the data format for the temperature. Negative numbers are represented in binary two's-complement format. After power-up or reset, the temperature register reads 0°C until the first conversion is complete.
