To support potential software polling/reconfiguration for functional reliability, MSMC does not trigger error status for configuration accesses to unimplemented addresses. All reads of unimplemented addresses return data as zero and writes are ignored. This model should support a simple DMA "read, compare, and write-back" model for checking the MSMC configuration state.
