Preliminary
Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
MII Register Receive Data
The MDRX bits represent the data that was read in the previous MII
management transaction.
