The temperature trip point registers and 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. As an example,
assuming an LSB of 0.0625°C:
• A value of 0x018C would equal 24.75°C
• A value of 0x06C0 would equal 108°C
• A value of 0x1E74 would equal –24.75°C
The upper and lower temperature boundary registers are used to set the maximum and
minimum values of the alarm window. LSB for these registers is 0.25°C. All RFU bits in
the register will always report zero.
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 zero.
