8.3 LED Signals
Table 21 lists the signals used for the LEDs. The LED signals are active high. All LEDs should be
green.
Table 21: LED Signals
Condition Name Direction Description
LED_LINK_ACT[0] OUTPUT Link/activity LED for
ethernet port 0
2 or 3 communication
ports
LED_LINK_ACT[1] OUTPUT Link/activity LED for
ethernet port 1
3 communication ports LED_LINK_ACT[2] OUTPUT Link/activity LED for
Ethernet port 2
RUN_LED enabled LED_RUN OUTPUT RUN LED for device status
Always 0 if RUN LED is
deactivated.
RUN_LED enabled and
Extended RUN/ERR
LED enabled
LED_ERR OUTPUT ERR LED for device
status.
LED_STATE_RUN OUTPUT Connect to RUN pin of
dual-color STATE LED,
connect LED_ERR to ERR
pin of STATE LED
NOTE: The application ERR LED and STATE LED can alternatively be controlled by a µController if required.
