The ISO/IEC specification defines bit 5.14 as the Acknowledge bit. When this bit is a:
•
•
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:
•
•
Note:
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:
•
•
IDT uses some reserved bits to invoke auxiliary functions. To ensure proper operation of the ICS1893CF,
an STA must maintain the default value of these bits. Therefore, IDT recommends that an STA always write
the default value of any reserved bits during all management register write operations.
The Selector Field bits indicate the technology or encoding that the remote link partner is using for the
Auto-Negotiation message. The ICS1893CF 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:
•
•
Zero, it indicates that the remote link partner has not received the ICS1893CF Link Control Word.
One, it indicates to the ICS1893CF / STA that the remote link partner has acknowledged reception of the
ICS1893CF Link Control Word.
Zero, it indicates that the remote link partner detects a Link Fault.
One, it indicates to the ICS1893CF / STA that the remote link partner detects a Link Fault.
Read by an STA, the ICS1893CF returns a logic zero.
Written to by an STA, the STA must use the default value specified in this data sheet.
00001b (IEEE Std 802.3)
00010b (IEEE Std 802.9)
