0x0000 MII read data
Read data is obtained by reading from this register
after an MII Management read cycle. An MII
Management read cycle is executed by loading the
MII Management Address register, then setting the
READ bit to 1 in the MII Management Command
register (see page 360). Read data is available after the
BUSY bit in the MII Management Indicators register
(see page 363) returns to 0.
