Notes
The shutdown mode is a power-saving mode that dis-
ables the temperature sensor.
When enabled, a hysteresis is applied to temperature
movement around the trip points (see Figure 4
(page 18)). As an example, if the hysteresis register
is enabled to a delta of 6°C, the preset trip points will
toggle when the temperature reaches the program-
med value. These values will reset when the tempera-
ture drops below the trip points minus the set
hysteresis level. In this case, this would be critical tem-
perature minus 6°C.
The hysteresis is applied to both the above alarm win-
dow and the below alarm window bits found in the
read-only temperature register (see Table 20
(page 18)). EVENT# is also affected by this register.
