Alert Operation Modes
The following table defines the content of the registers TLOW and THIGH. For data transmission, the
MSB byte is transmitted first, followed by the LSB byte. The data format for representing the threshold
temperatures is equal to the temperature register (TVAL). After a power-up, the registers are initialized
with the following default values:
