This variable is the external fault flags. Unlike the other faults, the fault message and the class of each of these
faults is user definable. It is bit encoded as shown below:
xxx1H - external 1 [512]
xxx2H - external 2 [513]
xxx4H - external 3 [514]
xxx8H - external 4 [515]
xx1xH - external 5 [516]
xx2xH - external 6 [517]
xx4xH - external 7 [518]
xx8xH - external 8 [519]
x1xxH - external 9 [520]
x2xxH - external 10 [521]
x4xxH - external 11 [522]
x8xxH - external 12 [523]
1xxxH - external 13 [524]
2xxxH - external 14 [525]
4xxxH - external 15 [526]
8xxxH - external 16 [527]
Warning Flags A [Warning flags A]
Linear number:
373
Minimum value: 0000 Hex
Maximum value: FFFF Hex
