9.5.1.1 Temperature Register (address = 00h) [default reset = 0000h]

The temperature register of the TMP1075 is a 12-bit, read-only register that stores the result of the most recent conversion (see Figure 9-11). Data is represented in binary two's complement format. The first 12 bits are used to indicate temperature, with all remaining bits equal to zero. The least significant byte does not have to be read if that information is not needed. Following power-up or reset, the temperature register value is 0°C until the first conversion is complete.
