Auto Negotiation
The KSZ8862M conforms to the auto negotiation protocol as described by the 802.3 committee to allow the channel to
operate at 10Base-T or 100Base-TX on port 2 only.
Auto negotiation allows unshielded twisted pair (UTP) link partners to select the best common mode of operation. In auto
negotiation, the link partners advertise capabilities across the link to each other. If auto negotiation is not supported or the
link partner to the KSZ8862M is forced to bypass auto negotiation, the mode is set by observing the signal at the receiver.
This is known as parallel mode because while the transmitter is sending auto negotiation advertisements, the receiver is
listening for advertisements or a fixed signal protocol.
The link setup is shown in the following flow diagram (Figure 6).
