The upper and lower temperature boundary registers are used to set the maximum and
minimum values of the alarm window. LSB for these registers is 0.25°C. All RFU bits in
the register will always report zero.
The critical temperature register is used to set the maximum temperature above the
alarm window. The LSB for this register is 0.25°C. All RFU bits in the register will always
report zero.
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.
