8.3.9
Remote Fault (bit 1.4)
An STA reads bit 1.4 to determine if a Remote Fault exists. The ICS1893AF sets bit 1.4 based on the
Remote Fault bit received from its remote link partner. The ICS1893AF receives the Remote Fault bit as
part of the Link Code Word exchanged during the auto-negotiation process. If the ICS1893AF receives a
Link Code Word from its remote link partner and the Remote Fault bit is set to:
Zero, then the ICS1893AF sets bit 1.4 to logic zero.
One, then the ICS1893AF sets bit 1.4 to logic one. In this case, the remote link partner is reporting the
detection of a fault, which typically occurs when the remote link partner is having a problem with its
receive channel.
Bit 1.4 is a latching high status bit. (For more information on latching high and latching low bits, see Section
Note:
The ICS1893AF has two versions of the Remote Fault bit.
One version of the Remote Fault bit is a latching high version. An STA can access this version
through either Management Register 1 (bit 1.4) or 17 (bit 17.1). This bit 1.4/17.1 is cleared when
an STA reads either of these registers. (Bit 1.4 is identical to bit 17.1 in that they are the same
internal bit.)
Another version of the Remote Fault bit is updated whenever the ICS1893AF receives a new
Link Control Word. An STA can access this version through Management Register 5 (bit 5.13),
which like bits 1.4/17.1, also reports the status of the Remote Fault bit received from the remote
link partner. However, bit 5.13 is not a latching high bit.
The operation of both bit 1.4/17.1 and bit 5.13 are in compliance with the IEEE Std 802.3u.
8.3.10
Auto-Negotiation Ability (bit 1.3)
The STA reads bit 1.3 to determine if the ICS1893AF can support the auto-negotiation process. If the
ICS1893AF:
Cannot support the auto-negotiation process, it clears bit 1.3 to logic zero.
Can support the auto-negotiation process, it sets bit 1.3 to logic one. (For the ICS1893AF, the default
value of bit 1.3 is logic one.)
