7.6 Register 4: Auto-Negotiation Register

Table 7-11 lists the bits for the Auto-Negotiation Register. An STA uses this register to select the

ICS1893BF capabilities that it wants to advertise to its remote link partner. During the auto-negotiation

process, the ICS1893BF advertises (that is, exchanges) capability data with its remote link partner by using

a pre-defined Link Code Word. The Link Code Word is embedded in the Fast Link Pulses exchanged

between PHYs when the ICS1893BF has its Auto-Negotiation sublayer enabled. The value of the Link

Control Word is established based on the value of the bits in this register.

Note: For an explanation of acronyms used in Table 7-5, see Chapter 1, “Abbreviations and Acronyms”.

† 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.

7.6.1 Next Page (bit 4.15)

This bit indicates whether the ICS1893BF uses the Next Page Mode functions during the auto-negotiation

process. If bit 4.15 is logic:

• Zero, then the ICS1893BF indicates to its remote link partner that these features are disabled. (Although

the default value of this bit is logic zero, the ICS1893BF does support the Next Page function.)

• One, then the ICS1893BF advertises to its remote link partner that this feature is enabled.
