EMAC 2 Interface
LAN 1 Transmit Coding Error. When EM1_TXER is asserted for
one or more EM1_TX_CLK periods while EM1_TX_EN is also
asserted, the LAN 1 EPHY emits one or more symbols that are not
part of the valid data or delimiter set somewhere in the frame being
transmitted. Permissible encoding of EM1_TXER with EM1_TX_EN
and EM1_TXD[3:0] are:
For MII, connect to LAN 1 EPHY TXER pin.
For 7-WS interface, leave open.
