The ‘fault type’ registers are a bit-field representation of which phases were driven by the
event system, and are the same information used to generate the faulted phase strings in
the soelog. Bit0 is A, Bit1 is B, Bit2 is C. The ‘fault distance’ registers are integer
representations of the per-unit distance, in DIV1000 or DIV100 format pending exact
configuration implementation.
