7.3.2 Temperature Result and Limits

At the end of every conversion or averaging cycle, the device updates the temperature register with the conversion result. The data reading in the result register is in two's complement format, has a data width of 16 bits, and a resolution of 7.8125 m°C. Table 1 shows multiple examples of possible binary data that can be read from the temperature result register and the corresponding hexadecimal and decimal equivalents.

The TMP116 also has alert status flags and alert pin functionality that use the temperature limits stored in the low limit register and high limit register. The alert registers use the same data format as the temperature register.
