Notes:
The temperature trip point registers and temperature readout register use a 2’s comple-
ment 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 would equal 24.75°C
• A value of 0x06C0 would equal 108°C
• A value of 0x1E74 would equal –24.75°C
