6.1.3.2. Status LED Control Signals

Table 75.  Status LED Interface Signals
Name I/O Description
led_link O When asserted, this signal indicates a successful link synchronization.
led_panel_link O When asserted, this signal indicates the following behavior:
Mode Signal Behavior
1000 Base-X without auto negotiation Similar to led_link
SGMII mode without auto negotiation Similar to led_link
1000 Base-X with auto negotiation Similar to led_an
SGMII mode with MAC mode auto negotiation Similar to led_an and partner_ability [15]
SGMII mode with PHY mode auto negotiation Similar to led_an and dev_ability [15]
led_crs O When asserted, this signal indicates some activities on the transmit and receive paths. When deasserted, it indicates no traffic on the paths.
led_col O When asserted, this signal indicates that a collision was detected during frame transmission. This signal is always deasserted when the PCS function operates in standard 1000BASE-X mode or in full-duplex mode when SGMII is enabled.
led_an O Auto-negotiation status. The PCS function asserts this signal when an auto-negotiation completes.
led_char_err O 10-bit character error. Asserted for one tbi_rx_clk cycle when an erroneous 10-bit character is detected.
led_disp_err O 10-bit running disparity error. Asserted for one tbi_rx_clk cycle when a disparity error is detected. A running disparity error indicates that more than the previous and perhaps the current received group had an error.
