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.
Speed Change: Asserted when the speed of a link changes.
Link Change: Asserted when a link is established or broken.
Duplex Change: Asserted when the duplex mode of a link
changes.
MDIX Change: Asserted when the MDIX status changes, i.e. a
pair swap occured.
Polarity Change: Asserted when the polarity of any channel
changes.
Parallel Detection Fault: Asserted when a parallel detectin fault
has been detected.
Master / Slave Error: Asserted when the Master / Slave config-
uration in 1000BASE-T mode could not be resolved.
No HCD: Asserted when Auto-Negotiation could not determine a
Highest Common Denominator.
No Link after Auto-Negotiation: Asserted when Auto-Negotia-
tion has been completed successfully and no link could be estab-
lished.
Jabber Change: Asserted in 10BASE-T mode when a Jabber
condition has occured or has been cleared.
Next Page Received: Asserted when a Next Page has been re-
ceived.
Auto-negotiation complete: Asserted when Auto-Negotiation
has been completed.
Remote Fault Change: Asserted when the remote fault status
changes.
