Ports in the following table are available when Clause 74 (BASE-KR FEC) is selected from the Configuration tab.
| Name | Size | I/O | Description |
|---|---|---|---|
| ctl_fec_tx_enable_* | 1 | I | Asserted to enable the clause 74 FEC encoding on the transmitted data. |
| ctl_fec_rx_enable_* | 1 | I | Asserted to enable the clause 74 FEC decoding of the received data. |
| ctl_fec_enable_error_to_pcs_* | 1 | I | Clause 74 FEC enable error to pcs. |
| stat_fec_inc_correct_count_* | 4 | O | This signal will be asserted roughly every 32 words, while the ctl_rx_fec_enable is asserted, if the FEC decoder detected and corrected a bit errors in the corresponding frame. |
| stat_fec_inc_cant_correct_count_* | 4 | O | This signal will be asserted roughly every 32 words, while the ctl_rx_fec_enable is asserted, if the FEC decoder detected bit |
| stat_fec_lock_error_* | 4 | O | stat_fec_lock_error_* is asserted if the FEC decoder has been unable to detect the frame boundary after about 5 ms. It is cleared when the frame boundary is detected. |
| stat_fec_rx_lock_* | 4 | O | This signal is asserted while the ctl_fec_rx_enable is asserted when the FEC decoder detects the frame boundary. |
