The local device’s remote fault condition is encoded in bits 2 and 3 of the base page. Values are shown in
the following table. The default value is 00. Indicate a fault by setting a non-zero remote fault encoding and
re-negotiating.
Reserved, should be cleared.
The local device’s PAUSE capability is encoded in bits 7 and 8, and the decodes are shown in the following
table. For priority resolution information consult
Half-duplex capability.
0 Designates local device as not capable of half-duplex operation.
1 Designates local device as capable of half-duplex operation.
Full-duplex capability.
0 Designates the local device as not capable of full-duplex operation.
1 Designates the local device as capable of full-duplex operation.
Reserved, should be cleared.
