Ah yes. this works:
                 QWordMemory (
                         ResourceProducer, PosDecode, MinFixed, MaxFixed,
                         NonCacheable, ReadWrite,
                         0x0000000000000000,
                         0x0000000ffffffff0,
                         0x0000000fffffffff,
                         0x0000000000000000,
                         0x0000000000000010,
                         ,, _Y02)
