PRODUCTION DATA
The Media Independent Interface is a synchronous 4-bit wide nibble data interface that connects the PHY to the MAC. The MII is fully compliant with IEEE 802.3-2002 clause 22.
The MII signals are summarized in Table 6-1.
FUNCTION | PINS |

Data Signals | TX_D[3:0] |

Transmit and Receive Signals | TX_EN |
RX_DV |
Additionally, the MII interface includes the carrier sense signal (CRS), as well as a collision detect signal (COL). The CRS signal asserts to indicate the reception or transmission of data. The COL signal asserts as an indication of a collision which can occur during half-duplex mode when both transmit and receive operations occur simultaneously.
