The t~, tempB, and pelk buffer fields contain the values of the corresponding on-chip registers at the time of the fault. If the fault is associated with object qualification, the directory

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.
