3.1.2. Performing a Temperature Measurement
The following steps should be performed in sequence to take a temperature measurement:
6. Set START (D0) and TEMP (D4) in CONFIG (register 0x03) to begin a new conversion, i.e., write CONFIG with
0x11
7. Poll RDY (D0) in STATUS (register 0) until it is low (=0)
8. Read the upper and lower bytes of the temperature value from DATAh and DATAl (registers 0x01 and 0x02),
respectively
Table 12 shows the format of the 14-bit temperature result. This value may be converted to °C using the following
equation:
where TEMP is the measured value returned in DATAh:DATAI.
Table 13shows the 14-bit values that correspond to various measured temperature levels.

The above sequence assumes normal mode, i.e., t_CONV = 35 ms (typical). Conversions may be performed in fast
mode. See section “5.1.3. Fast Conversion Mode”.
