Ethernet Interface
EMC0MDClk
Management Data Clock. The MDClk is sourced to the
PHY. Management information is transferred
synchronously with respect to this clock (MII, RMII, and
SMII).

EMC0MDIO
Management Data Input/Output is a bidirectional signal
between the Ethernet controller and the PHY. It is used to
transfer control and status information (MII, RMII, and
SMII).
