7.6 Register 4: Auto-Negotiation Register
7.6.1 Next Page (bit 4.15)
ICS1893CK-40, Rev. C, 06/02/09
Table 7-11
ICS1893CK-40 capabilities that it wants to advertise to its remote link partner. During the auto-negotiation
process, the ICS1893CK-40 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 ICS1893CK-40 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:
Table 7-11. Auto-Negotiation Advertisement Register (register 4 [0x04])
† As per the IEEE Std 802.3u, during any write operation to any bit in this register, the STA must write the default value
This bit indicates whether the ICS1893CK-40 uses the Next Page Mode functions during the
auto-negotiation process. If bit 4.15 is logic:

Zero, then the ICS1893CK-40 indicates to its remote link partner that these features are disabled.
(Although the default value of this bit is logic zero, the ICS1893CK-40 does support the Next Page
function.)
One, then the ICS1893CK-40 advertises to its remote link partner that this feature is enabled.
