Elements of the CME Display
Considerations

When a CME is detected during an access attempt to a specific memory location,
the CME interrupt handler is invoked. The memory manager determines if the CME
is a soft CME or a hard CME. In general, a soft CME is one that occurs on the first
access to a specific memory location but does not occur on the second and
subsequent accesses to the same location. A hard CME is one that continues to
occur during consecutive access attempts. However, a soft CME can be
reclassified as a hard CME if it occurs too frequently.

The physical pages are in reverse order, so the newest page number appears first.

The list of soft CME pages clears approximately every 14 days. The list of hard
CME pages never clears.
