MDIO RA 4—Auto-Negotiation Advertisement Register

Figure 4-4 shows the format for the auto-negotiation (AN) advertisement register,
MDIO RA 4, in the MC92603.

NOTE

The ‘Ack’ bit is set when three consecutive matching
configuration registers are received. The auto-negotiation state
is complete when three consecutive matching configuration
registers are received with the ‘Ack’ bit set. The transmitter
will continue sending auto-negotiation sequences once the
auto-negotiation sequence is complete for at least 10 ms.

Table 4-4 lists the corresponding field descriptions for the AN advertisement register.
