The temperature trip point registers and the temperature readout register use a
2’s complement format to enable negative numbers. The least significant bit (LSB) is
equal to 0.0625°C or 0.25°C, depending on which register is referenced. For example,
assuming an LSB of 0.0625°C:
• A value of 0x018C equals 24.75°C
• A value of 0x06C0 equals 108°C
• A value of 0x1E74 equals –24.75°C
The upper and lower temperature boundary registers are used to set the minimum and
maximum values of the alarm window. The LSB for these registers is 0.25°C. All RFU bits
in the register will always report 0s.
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 0s.
