2.0 Register Block (Continued)
5 reduced LED enable 0, RW Reduced LED Mode Enable: This bit enables the reduced LED
(RLED) mode that is different from the normal five-LED mode. In
the RLED Mode, 10M Link LED is changed to link LED or Link
and activity combined LED.
When reg 0x13.5 is enabled:
Reg 0x1A.0 = 1 - 10M Link LED displays 10/100/1000 Link
Reg 0x1A.0 = 0 - 10M LED displays 10/100/1000 Link and ACT
Note: In Link mode, the LED is steady on. In Link/ACT mode,
LED is steady on when link is achieved, and LED blinks when
there is link and activity.
4 led_on_crc 0, RW
3 led_on_ie 0, RW
2 an_fallback_an 0, RW
