7.5.1.2 Configuration Register (address = 01h) [default reset = 00FFh (60A0h TMP1075N)]

The configuration register is an 16-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. Figure 7-12 shows the format of the configuration register for the TMP1075, followed by a breakdown of the register bits. The power-up or reset value of the configuration register are all bits equal to 00FFh (TMP1075N: 60A0h). Only single byte writes and reads must be used when pointing to the configuration register for proper operation on the TMP1075N orderable.

Note:

The configuration register supports single-byte read and write over I2C bus to verify software compatibility with other xx75 standard temperature sensors like TMP75 and LM75. When a single byte write is performed, the data byte on the I2C bus updates the register bits 15-8. Similarly when a single byte read is performed, the data bits 15-8 is transferred over the I2C bus.
