Description
Default
RO Flow control capability of the link partner of external PHY on MII0 1
1: link partner supports flow control,
0: link partner does not support flow control
RO Mac_force[0]
1: MII0’s speed and duplex are forced because IP175C/IP175CH
finds external PHY doesn’t support SMI
0: MII0 polls external PHY through SMI to decide its speed and duplex.
RO MII0_link
1: link ok, 0: un-link
