The data format for the critical temperature value is in
two’s complement with one LSB = 0.25°C. Critical tem-
The data format is two’s complement with one LSB =
0.125°C. All unused bits are set to zero. The most sig-
nificant bit has a resolution of 128°C. The trip status bits
represent the internal temperature trip detection, and

Below alarm window
0 = Temperature is equal to or above the alarm window lower boundary temperature
1 = Temperature is below the alarm window (temperature < alarm temperature lower boundary minus the hysteresis)
Above alarm window
0 = Temperature is equal to or below the alarm window upper boundary temperature minus the hysteresis
1 = Temperature is above the alarm window (temperature > alarm temperature upper boundary)
Above critical trip
0 = Temperature is below the critical temperature setting minus the hysteresis
1 = Temperature is equal to or above the critical temperature setting (temperature ≥ critical temperature)

ration bits (e.g., event output control, clear event, etc.).
If neither the above alarm window (bit 14) nor the below
alarm window (bit 13) are set (i.e., both are 0), the cur-
rent temperature is within the alarm window.
