temperature limits. The temperature hysteresis value is stored in

straight binary format using the four LSBs. Increments are possible

in steps of 1°C from 0°C to 15°C. The value in this register is

the overtemperature limit value. An overtemperature event occurs

when the temperature value stored in the temperature value

register exceeds the value stored in this register. The INT pin is

activated if an overtemperature event occurs. The temperature

is stored in twos complement format with the most significant

bit being the temperature sign bit.

the undertemperature limit value. An undertemperature event

occurs when the temperature value stored in the temperature

value register is less than the value stored in this register. The

INT pin is activated if an undertemperature event occurs. The

temperature is stored in twos complement format with the MSB

being the temperature sign bit.
