3.3 Packet Interfaces
3.3.1 MII Interfaces
Data for the MII packet switching is based on Specification IEEE Std 802.3u – 1995. The MII has separate
transmit and receive circuits, and consequently the characteristics are shown in the relevant tables.
All MII signals are 5 V tolerant.
All MII outputs are high impedance while S_RST is low.
