This register is used to store the unsigned value of the input for the high threshold decoder:

Threshold = (TEMP_H_LIMIT - 63)*0.64°C

If the register value is set to 00h, then the high interrupt is disabled. See Section 7 Interrupt.

This register is used to store the unsigned value of the input for the low threshold decoder:

Threshold = (TEMP_L_LIMIT - 63)*0.64°C

If the register value is set to 00h, then the low interrupt is disabled. See Section 7 Interrupt.
