8.6 Register 4: Auto-Negotiation Register

8.6.2 IEEE Reserved Bit (bit 4.14)
ICS1893AF, Rev D 10/26/04
Table 8-11
ICS1893AF capabilities that it wants to advertise to its remote link partner. During the auto-negotiation
process, the ICS1893AF 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 ICS1893AF 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 8-11. 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 ICS1893AF uses the Next Page Mode functions during the auto-negotiation
process. If bit 4.15 is logic:
•
•
The ISO/IEC specification reserves this bit for future use. However, the ISO/IEC Standard also defines bit
4.14 as the Acknowledge bit.

Zero, then the ICS1893AF indicates to its remote link partner that these features are disabled. (Although
the default value of this bit is logic zero, the ICS1893AF does support the Next Page function.)
One, then the ICS1893AF advertises to its remote link partner that this feature is enabled.
