LOS HI: High alarm status for RSSI; fast comparison. A TXD event does not clear this alarm.
0 = (default) Last comparison was below threshold setting.
1 = Last comparison was above threshold setting.
BIT 6
LOS LO: Low alarm status for RSSI; fast comparison. A TXD event does not clear this alarm.
0 = (default) Last comparison was above threshold setting.

TEMP HI: High warning 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 warning 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 warning 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 warning 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.
