Live Rx Faults are returned as a 32 bit Hexadecimal value. Bit values
are defined as follows:
80000000 = Demodulator IF not locked
40000000 = Demodulator Data Decoder not locked
20000000 = Demodulator RF Synthesizer not locked
10000000 = Demodulator No IQ Activity
08000000 = Interface De-Multiplexers not locked
04000000 = Interface Buffer Fault
02000000 = Interface Buffer about to slip
01000000 = Interface Buffer has overflowed
00800000 = Interface Buffer has underflowed
00400000 = Interface Buffer Clock PLL not locked
00200000 = Interface Buffer Clock Reference Activity
00100000 = Interface Data/AIS
00080000 = Eb/No Threshold exceeded
