Bit

Bit Name

Default

Description

0, RO

Next Page Indication:

0 = Link Partner does not desire Next Page Transfer.

1 = Link Partner desires Next Page Transfer.

ACK

0, RO

Acknowledge:

1 = Link Partner acknowledges reception of the ability data word.

0 = Not acknowledged.

The Device’s Auto-Negotiation state machine will automatically

control this bit based on the incoming FLP bursts. Software

should not attempt to write to this bit.
