7.3.2.4.4 Hysteresis
If a monitored signal is out of range and the alarm is enabled, the corresponding alarm bit is set to 1. However, the alarm condition is cleared only when the conversion result returns either a value lower than the high threshold register setting or higher than the low threshold register setting by the number of codes specified in the hysteresis setting (see Figure 57). The ADC and LT hysteresis registers (address 0xA0 through 0xA4) store the hysteresis value for the external unipolar inputs and internal temperature sensor programmable alarms. The hysteresis is a programmable value between 0 LSB to 127 LSB for the unipolar inputs alarms and 0°C to 31°C for the internal temperature-sensor alarms. The die thermal alarm hysteresis is fixed at 8°C.
