7.7 Register 5: Auto-Negotiation Link Partner Ability Register
Table 7-12 lists the bits for the Auto-Negotiation Link Partner Ability Register. An STA uses this register to
determine the capabilities being advertised by the remote link partner. During the auto-negotiation process,
the ICS1893BF advertises (that is, exchanges) the capability data with its remote link partner using a
pre-defined Link Code Word. The value of the Link Control Word received from its remote link partner
establishes the value of the bits in this register.
Note:
1. For an explanation of acronyms used in Table 7-12, see Chapter 1, “Abbreviations and Acronyms”.
2. The values in this register are valid only when the auto-negotiation process is complete, as indicated by
bit 1.5 or bit 17.4.
As per the IEEE Std 802.3u, during any write operation to any bit in this register, the STA must write the default value
to all Reserved bits.
7.7.1 Next Page (bit 5.15)
If bit 5.15 is logic:
Zero, then the remote link partner is indicating that this is the last page being transmitted.
One, then the remote link partner is indicating that additional pages follow.
