When one side of the MCU cache is blocked, duplex TrueCopy for Mainframe pairs are not
affected, but pending duplex TrueCopy for Mainframe pairs are suspended. Suspending TrueCopy
for Mainframe pairs with pending duplex status provides additional protection in the unlikely event
of a cache failure.
