Assignments
Table 3. Temperature Register
D15: MSB is the first sign bit.
D2, D1, D0: Flag bits for T
1LSB = 0.0625°C.
Temperature is stored in two’s complement format.
Table 4. Configuration Register
Power-on default = 0h.
D0: 0 = normal operation; 1 = shutdown.
D1: 0 = comparator mode; 1 = interrupt mode.
D2 to D3: 0 = active low; 1 = active high.
D5: 0 = normal SMBus operation; 1 = full I
D7 to D6: Reserved locations, always write zeros.
