PRODUCTION DATA.
The THERM Hysteresis Register (see Table 15) stores the hysteresis value used for the THERM pin alarm function. This register must be programmed with a value that is less than the Local Temperature High Limit Register value, Remote Temperature High Limit Register value, Local THERM Limit Register value, or Remote THERM Limit Register value; otherwise, the respective temperature comparator does not trip on the measured temperature falling edges. Allowable hysteresis values are l in Table 13. The default hysteresis value is 10°C, whether the device is operating in the standard or extended mode setting.
