3.3:0 - Vendor Revision Number
The current Revision Number of this IC is ‘0001’.
25.3.5 Register 4 (04h) – Auto-Negotiation Advertisement Register
25.3.5.1 Clause 28 View
This register controls the advertised abilities of the local (not remote) PHY. The state of this register is latched when the Auto-
Negotiation state machine enters the ABILITY_DETECT state. Thus, any writes to this register prior to completion of Auto-
Negotiation as indicated by MII Register
Auto-Negotiation. Once Auto-Negotiation has completed, this register value may be read via the SMI to determine the highest
common denominator technology.
4.15 – Auto-Negotiation Additional Next-Page Transmission Request
The VSC8211 supports additional Next-Page transmission through MII Register bit 4.15. See description of MII
for more details on Next-Page exchanges. This bit is only supported on copper media.
4.14, 4.12 – Reserved
4.13 – Transmit Remote Fault
This bit is used by the local MAC to communicate a fault condition to the link partner during auto-negotiation. This bit does not
have any effect on the local PHY operation. This bit is automatically cleared following a successful negotiation with the Link
Partner. Note that IEEE Clause-37 provides for two remote fault bits, while Clause-28 provides only a single remote fault bit.
This discrepancy is handled in MII Extended Register bits
Mapping
4.11 – Advertise Asymmetric Pause Capability
This bit is used by the local MAC to communicate Asymmetric Pause Capability to the link partner during auto-negotiation. This
has no effect on PHY operation. Changing this bit in Clause-28 view will also change bit 4.8 in Clause-37 view.
4.10 – Advertise Symmetric Pause Capability
This bit is used by the local MAC to communicate Symmetric Pause Capability to the link partner during autonegotiation. This
has no effect on PHY operation. Changing this bit in Clause-28 view will also change bit 4.9 in Clause-37 view.
