ADT75
Temperature Value Register
This 16-bit read only register stores the temperature measured by the internal temperature sensor. The temperature is stored in twos
complement format with the MSB being the temperature sign bit. When reading from this register, the eight MSBs (Bit D15 to Bit D8) are
read first and then the eight LSBs (Bit D7 to Bit D0) are read. The control register settings are the default settings on power up.
