The temperature register is a read-only register that provides the current temperature
detected by the temperature sensor. The LSB for this register is 0.0625°C with a resolu-
tion of 0.0625°C. The most significant bit (MSB) is 128°C in the readout section of this
register.
The upper three bits of the register are used to monitor the trip points that are set in the
previous three registers.
