Temperature data format
Table 3 shows the relationship between the output digital data and the external temperature.
Temperature data for the temperature, TOS, and THYS registers is represented as a 9-bit,
two’s complement word.
The left-most bit in the output data stream contains temperature polarity information for
each conversion. If the sign bit is '0', the temperature is positive and if the sign bit is '1,' the
temperature is negative.
