BIT 7
RSSI HI: High alarm status for RSSI measurement. A TXD event does not clear this alarm.
0 = (default) Last measurement was equal to or below the threshold setting.
1 = Last measurement was above the threshold setting.
BIT 6
RSSI LO: Low alarm status for RSSI measurement. A TXD event does not clear this alarm.
0 = (default) Last measurement was equal to or above the threshold setting.
1 = Last measurement was below the threshold setting.

BIT 0
FLTINT: FAULT interrupt. This bit is the wire-ORed logic of all alarms and warnings wire-ANDed with
their corresponding enable bits. The enable bits are found in Table 01h/05h, Registers F8h–FFh.
