7.5.2 Temperature Register

The temperature register of the TMP102-Q1 device is configured as a 12-bit, read-only register (configuration register EM bit = 0, see the Section 7.4.2 section), or as a 13-bit, read-only register (configuration register EM bit = 1) that stores the output of the most recent conversion. To obtain data as described in Table 7-8 and Table 7-9 read two bytes. Note that byte 1 is the most-significant byte (MSB), followed by byte 2, the least-significant byte. The first 12 bits (13 bits in extended mode) indicate temperature. The LSB does not must be read if that information is not needed.
