Enhanced LED Behavior, Address 17E (0x11) (continued)
Note
LED control. If set to 0, then the LED features in 16E and 17E are not relevant. If set to
1, then the LED features in register 27 are not relevant.
CRC Good Counter
Register 31E makes it possible to read the contents of the CRC good counter; the
number of CRC routines that have executed successfully. The following table lists the
possible readouts.

Description
This is a sticky bit.
1 = Enhanced LED method (controlled by MII
register 16E and 17E).
0 = Simple LED method (controlled by MII
register 27).
This is a sticky bit.
0 = Combine enabled (Link/Activity, Duplex/
Collision).
1 = Disable Combination (Link only, Duplex
only).
This is a sticky bit.
0 = Combine enabled (Link/Activity, Duplex/
Collision).
1 = Disable Combination (Link only, Duplex
only).
This is a sticky bit.
0 = Combine enabled (Link/Activity, Duplex/
Collision).
1 = Disable Combination (Link only, Duplex
only).
This is a sticky bit.
0 = Combine enabled (Link/Activity, Duplex/
Collision).
1 = Disable Combination (Link only, Duplex
only).
Description
This is a self-clearing bit.
1 = Packet received since last read.
This is a self-clearing bit.
Counter containing the number of packets
with valid CRCs. This counter does not stop
counting and will roll over.
