determine the capabilities being advertised by the remote link partner. During the auto-negotiation process,
the ICS1893 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
2. The values in this register are valid only when the auto-negotiation process is complete, as indicated by
Table 8-12.
† As per the IEEE Std 802.3u, during any write operation to any bit in this register, the STA must write the default value
