* When one side of the MCU cache is blocked, duplex Continuous Access Synchronous Z pairs are not affected, but
pending duplex Continuous Access Synchronous Z pairs are suspended. Suspending Continuous Access Synchronous
Z pairs with pending duplex status provides additional protection in the unlikely event of a cache failure.
