PHY Mode SMI Managed
In PHY mode SMI managed, the internal PHYs, Virtual PHY, and SMI slave block are accessed via
the MII management pins. The PMI is 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
