ICS1893AF Data Sheet - Release

8.8.2

Parallel Detection Fault (bit 6.4)

The ICS1893AF sets this bit to a logic one if a parallel detection fault is encountered. A parallel detection

fault occurs when the ICS1893AF cannot disseminate the technology being used by its remote link partner.

Bit 6.4 is a latching high (LH) status bit. (For more information on latching high and latching low bits, see

Section 8.1.4.1, “Latching High Bits” and Section 8.1.4.2, “Latching Low Bits”.)

8.8.3

Link Partner Next Page Able (bit 6.3)

Bit 6.3 is a status bit that reports the capabilities of the remote link partner to support the Next Page

features of the auto-negotiation process. The ICS1893AF sets this bit to a logic one if the remote link

partner sets the Next Page bit in its Link Control Word.

8.8.4

Next Page Able (bit 6.2)

Bit 6.2 is a status bit that reports the capabilities of the ICS1893AF to support the Next Page features of the

auto-negotiation process. The ICS1893AF sets this bit to a logic one to indicate that it can support these

features.

8.8.5

Page Received (bit 6.1)

The ICS1893AF sets its Page Received bit to a logic one whenever a new Link Control Word is received

and stored in its Auto-Negotiation link partner ability register. The Page Received bit is cleared to logic zero

on a read of the Auto-Negotiation Expansion Register.

Bit 6.1 is a latching high (LH) status bit. (For more information on latching high and latching low bits, see

Section 8.1.4.1, “Latching High Bits” and Section 8.1.4.2, “Latching Low Bits”.)

8.8.6

Link Partner Auto-Negotiation Able (bit 6.0)

If the ICS1893AF:

• Does not receive Fast Link Pulse bursts from its remote link partner, then this bit remains a logic zero.

• Receives valid FLP bursts from its remote link partner (thereby indicating that it can participate in the

auto-negotiation process), then the ICS1893AF sets this bit to a logic one.
