0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
TEMP LO: Low Alarm Status for Temperature measurement.
0 = (Default) Last measurement was equal to or above threshold setting.
1 = Last measurement was below threshold setting.
V CC HI: High Alarm Status for V CC measurement.
0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
V CC LO: Low Alarm Status for V CC measurement. This bit is set when the V CC supply is below the
POA trip point value. It will clear itself when a V CC measurement is completed and the value is above
the low threshold.
0 = Last measurement was equal to or above threshold setting.
1 = (Default) Last measurement was below threshold setting.
MON1 HI: High Alarm Status for MON1 measurement.
0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
MON1 LO: Low Alarm Status for MON1 measurement.
0 = (Default) Last measurement was equal to or above threshold setting.
1 = Last measurement was below threshold setting.
MON2 HI: High Alarm Status for MON2 measurement.
0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
MON2 LO: Low Alarm Status for MON2 measurement.
0 = (Default) Last measurement was equal to or above threshold setting.
1 = Last measurement was below threshold setting.
