PRODUCTION DATA
The device continuously monitors the analog input channels and temperatures. If any alarms are out of range and the alarm is enabled, the alarm bit is set (1). However, the alarm condition is cleared only when the conversion result returns to a value of at least hys below the value of the high threshold register, or hys above the value of low threshold register. The hysteresis registers store the value for each analog input (CH0, CH1, CH2, and CH3) and temperature (D1, D2, and LT). hys is the value of hysteresis that is programmable: 0 LSB to 127 LSB for analog inputs, and 0°C to +31°C for temperatures. For the THERM-ALR bit, the hysteresis is fixed at 8°C. The hysteresis behavior is shown in Figure 7-16.
