MAC Mode SMI Managed
In MAC mode SMI managed, the internal PHYs and SMI slave block are accessed via the MII
management pins. The Virtual PHY and PMI are not used in this mode.
The Virtual PHY interface is accessible via the SMI slave or the EEPROM Loader. Refer to
9.2, "SMI Slave Controller," on page 125
