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 Data
This field contains the 16-bit data value read from the PHY after a
management read operation or the 16-bit data value to be written to the
PHY before a management write operation.
