7.5.2 Temperature Register

The Temperature register of the TMP175-Q1 or TMP75-Q1 is a 12-bit, read-only register that stores the output of

the most recent conversion. Two bytes must be read to obtain data and are described in Table 6 and Table 7.

Byte 1 is the most significant byte and is followed by byte 2, the least significant byte. 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 the power-up or reset value, the Temperature register reads 0°C until

the first conversion is complete.

7.5.3 Configuration Register

The Configuration register is an 8-bit read/write register used to store bits that control the operational modes of

the temperature sensor. Read and write operations are performed MSB first. The format of the Configuration

register for the TMP175-Q1 and TMP75-Q1 is shown in Table 8, followed by a breakdown of the register bits.

The power-up or reset value of the Configuration register are all bits equal to 0.
