6.2 TEMP_H_LIMIT (02h) - RW
7 6 5 4 3 2 1 0 THL7 THL6 THL5 THL4 THL3 THL2 THL1 THL0 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.
6.3 TEMP_L_LIMIT (03h) - RW
7 6 5 4 3 2 1 0 TLL7 TLL6 TLL5 TLL4 TLL3 TLL2 TLL1 TLL0 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.
