6.1.6.5. MII
Name | I/O | Description |
---|---|---|
MII Transmit Interface | ||
mii_tx_d[3:0] | I | MII transmit data bus. |
mii_tx_en | I | Assert this signal to indicate that the data on mii_tx_d[3:0]is valid. |
mii_tx_err | I | Assert this signal to indicate to the PHY device that the frame sent is invalid. |
MII Receive Interface | ||
mii_rx_d[3:0] | O | MII receive data bus. |
mii_rx_dv | O | Asserted to indicate that the data on mii_rx_d[3:0]is valid. The signal stays asserted during frame reception, from the first preamble byte until the last byte of the CRC field is received. |
mii_rx_err | O | Asserted by the PHY to indicate that the current frame contains errors. |
mii_col | O | Collision detection. Asserted by the PCS function to indicate that a collision was detected during frame transmission. |
mii_crs | O | Carrier sense detection. Asserted by the PCS function to indicate that a transmit or receive activity is detected on the Ethernet line. |
