The t~, tempB, and pelk buffer fields contain the values of the corresponding
index and object table index specify the object. The interpretation of the fault object selector/displacement vary depending on the fault.
The fault code, together with the operator id indicates the nature of the fault. The fault code field has the following format:
XRRXXXXX XXXXXXXX
RR TYPE Faults
10 MA Memory Access Faults.
11TS Test Segment Type or Descriptor Type Faults.
OX FF All other faults.
