SBOS397H August 2007 – December 2018 TMP102
The Temperature Register of the TMP102 is configured as a 12-bit, read-only register (Configuration Register EM bit = 0, see the Extended Mode section), or as a 13-bit, read-only register (Configuration Register EM bit = 1) that stores the output of the most recent conversion. Two bytes must be read to obtain data, and are described in Table 8 and Table 9. Note that byte 1 is the most significant byte, followed by byte 2, the least significant byte. The first 12 bits (13 bits in Extended mode) are used to indicate temperature. The least significant byte does not have to be read if that information is not needed.
