Datasheet
To detect the correct technology, the two register fields should be ANDed together to obtain the
highest common denominator. This value should then be used to map into a priority resolution
table used by the MAC driver to use the appropriate technology.
The following is an outline of the Auto-Negotiation process:
1. Receive 3 consecutive, matching code words
2. Set Acknowledge bit in transmit code word
3. Receive 3 consecutive, matching code words with Acknowledge bit set
4. Transmit 6 to 8 more code words with Acknowledge bit set
5. Determine operating mode via the priority table
6. Receive FLP from the link partner and record FLP in the MII register

Parallel Detect and Auto-Negotiation
The 82555 automatically determines the speed of the link either by using Parallel Detect or Auto-
Negotiation. Upon a reset, a link status fail, or a negotiate/renegotiate command, the 82555 inserts
a long delay during which no link pulses are transmitted. This period, known as Force_Fail, insures
that the 82555’s link partner has gone into a Link Fail state before Auto-Negotiation or Parallel
Detection begins. Thus, both sides (the 82555 and the 82555’s link partner) will perform Auto-
