AN Advertisement Register
Mnemonic: AN_ADV
Address: 58H
–
59H
The AN advertisement register contains the advertised ability of the local device. If another value
than the default value is written into this register, then Auto-Negotiation should be restarted by
setting bit GMII_CTL<RESAN>. In GPCS mode when Auto-Negotiation is not disabled, the
ASM_DIR and PAUSE bits contain the desired flow-control mode of operation. The actual
flow-control mode will be figured during the Auto-Negotiation process and will be reported in the
GPCS status register GPCS_STT.

Bit Description
Next page.
When set, indicates a request for next page exchange.
RESERVED
Remote fault.
The remote fault bits are used to notify the link partner about a fault that had occurred.
These bits are cleared after successful page exchanging. The table below specifies the
remote fault encoding.

Asymmetric PAUSE connection is desired.
When set, results in independent enabling/disabling of the flow-control receive and transmit.
When reset, results in symmetric enabling/disabling of the flow-control receive and transmit.
PAUSE function.
When set, indicates that the local device is capable and intends to stop upon reception of
flow-control packets as defined in IEEE 802.3x.
When reset, indicates that the local device is not capable or does not intend to stop upon
reception of a flow-control packet.
half-duplex ability.
This bit is fixed at a value of 0.
full-duplex ability.
This bit is fixed at a value of 1.
