LED3 Mode
This field specifies the control source for the LED3 output. An initial value of 0101b
selects the 1 Gb/s link indication.

LED3 Invert
This field specifies the polarity/inversion of the LED source prior to output or blink
control.
0b = Do not invert LED source.
1b = Invert LED source.
LED3_BLINK
31
0b¹
LED3 Blink
This field specifies whether or not to apply blink logic to the (inverted) LED control
source prior to the LED output.
0b = Do not blink LED output.
1b = Blink LED output.
1. These bits are read from the EEPROM.
The following mapping is used to specify the LED control source (MODE) for each LED output.

Asserted when any speed link is established and maintained.
Asserted when a 10 Gb/s link is established and maintained.
Asserted when link is established and packets are being transmitted or
received.
Asserted when link is established and packets are being transmitted or received
that passed MAC filtering.
Asserted when link is established and there is no transmit or receive activity.
Asserted when a 1 Gb/s link is established and maintained.
Reserved
Always asserted.
Always de-asserted.
Note: The dynamic LED modes (FILTER_ACTIVITY, LINK/ACTIVITY, and MAC_ACTIVITY) should be
used with LED Blink mode enabled.
