This data field contains the write data to be used when sourcing a write MII management frame.
This data field contains the read data resulting from a read MII management frame. RDATA is valid
only when MMCIF is set after a valid read frame operation.
This field must be programmed to 10 to generate a valid read frame operation. See
“Read
Section 11.4.6.3, “Write
BUSY is set is ignored. While programming MCMST, the OP write is ignored if MDCSEL is a 0
value. This field always reads 00.
