552 depends on PCC
555 The PCC Address Space also referred as PCC Operation Region pertains
556 to the region of PCC subspace that succeeds the PCC signature.
558 The PCC Operation Region works in conjunction with the PCC Table
559 (Platform Communications Channel Table). PCC subspaces that are
560 marked for use as PCC Operation Regions must not be used as PCC
562 MPST. These standard features must always use the PCC Table instead.
