BIT 7
TEMP HI: High alarm status for temperature measurement.
0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
BIT 6
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.
BIT 5
VCC HI: High alarm status for VCC measurement.
0 = (Default) Last measurement was equal to or below threshold setting
1 = Last measurement was above threshold setting.
BIT 4
VCC LO: Low alarm status for VCC measurement. This bit is set when the VCC supply is below the POA
trip point value. It clears itself when a VCC 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.
BIT 3
TXB HI: High alarm status for TXB measurement.
0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
BIT 2
TXB LO: Low alarm status for TXB measurement.
0 = (Default) Last measurement was equal to or above threshold setting.
1 = Last measurement was below threshold setting.
BIT 1
TXP HI: High alarm status for TXP measurement.
0 = (Default) Last measurement was equal to or below threshold setting.
1 = Last measurement was above threshold setting.
BIT 0
TXP LO: Low alarm status for TXP measurement.
0 = (Default) Last measurement was equal to or above threshold setting.
1 = Last measurement was below threshold setting.
