8.7.2
Acknowledge (bit 5.14)
The ISO/IEC specification defines bit 5.14 as the Acknowledge bit. When this bit is a:
Zero, it indicates that the remote link partner has not received the ICS1892 Link Control Word.
One, it indicates to the ICS1892 / STA that the remote link partner has acknowledged reception of the
ICS1892 Link Control Word.
8.7.3
Remote Fault (bit 5.13)
The ISO/IEC specification defines bit 5.13 as the Remote Fault bit. This bit is set based on the Link Control
Word received from the remote link partner. When this bit is a logic:
Zero, it indicates that the remote link partner does not have a Link Fault.
One, it indicates to the ICS1892 / STA that the remote link partner detects a Link Fault.
8.7.4
Technology Ability Field (bits 5.12:5)
The Technology Ability Field (TAF) bits (bits 5.12:5), determine the specific abilities that the remote link
partner is advertising. These bits are set based upon the Link Code Word received from the remote link
partner during the auto-negotiation process. The ISO/IEC specification defines the TAF technologies in
Annex 28B.
The ISO/IEC specification reserves bits 5.12:10 for future use. When each of these reserved bits is:
Read by an STA, the ICS1892 returns a logic zero.
Written to by an STA, the STA must use the default value specified in this data sheet.
ICS uses some of these reserved bits to invoke auxiliary functions. To ensure proper operation of the
ICS1892, an STA must maintain the default value of these bits. Therefore, ICS recommends that an STA
always write the default value of any reserved bits during all management register write operations.
To ensure proper operation of the ICS1892, an STA must maintain the default value of these bits.
Therefore, ICS recommends that an STA always write the default value of any reserved bits during all
management register write operations.
8.7.5
Selector Field (bits 5.4:0)
The Selector Field bits indicate the technology or encoding that the remote link partner is using for the
Auto-Negotiation message. The ICS1892 supports only IEEE Std 802.3, represented by a value of 00001b
in bits 5.4:0. The ISO/IEC standard defines the Selector Field technologies in Annex 28A. Presently, the
IEEE standard defines the following two valid codes:
00001b (IEEE Std 802.3)
00010b (IEEE Std 802.9)
