Figure 9. Equivalent Internal ESD Circuitry 7.3 Feature Description 7.3.1 Digital Temperature Output The digital output from each temperature measurement conversion is stored in the read-only temperature register. The temperature register of the TMP112 family 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 and Table 9. 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. The data format for temperature is listed in Table 2 and Table 3. One LSB equals 0.0625°C. Negative numbers are represented in binary twos complement format. Following power up or reset, the temperature register reads 0°C until the first conversion is complete. Bit D0 of byte 2 indicates normal mode (EM bit equals 0) or extended mode (EM bit equals 1), and can be used to distinguish between the two temperature register data formats. The unused bits in the temperature register always read 0.
