1. Because of the nature of the failure, there is no means of activating the FREEZE feature.
2. FREEZE is not activated, though activation is possible with the relevant command.
3. When one side of the MCU cache is blocked, Cnt Ac-S Z pairs in Duplex status are not affected, but Pending pairs are
suspended. Suspending pairs in Pending status provides additional protection against unexpected events caused by cache
failure.
