SLOS887E September 2014 – December 2018 TMP112-Q1
The temperature register of the TMP112-Q1 device is configured as a 12-bit read-only register (setting the EM bit to 0 in the configuration register; see the Extended Mode (EM) section), or as a 13-bit read-only register (setting the EM bit to 1 in the configuration register) that stores the output of the most recent conversion. Two bytes must be read to obtain data and are listed in Table 8. Byte 1 is the most significant byte (MSB), followed by byte 2, the least significant byte (LSB). 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.
