MF Preamble Suppression
This bit indicates whether the Virtual PHY accepts management frames with
the preamble suppressed.
0: Management frames with preamble suppressed not accepted
1: Management frames with preamble suppressed accepted
Auto-Negotiation Complete
This bit indicates the status of the Auto-Negotiation process.
0: Auto-Negotiation process not completed
1: Auto-Negotiation process completed
Remote Fault
This bit indicates if a remote fault condition has been detected.
0: No remote fault condition detected
1: Remote fault condition detected
Auto-Negotiation Ability
This bit indicates the status of the Virtual PHY’s auto-negotiation.
0: Virtual PHY is unable to perform auto-negotiation
1: Virtual PHY is able to perform auto-negotiation
Link Status
This bit indicates the status of the link.
0: Link is down
1: Link is up
Jabber Detect
This bit indicates the status of the jabber condition.
0: No jabber condition detected
1: Jabber condition detected
Extended Capability
This bit indicates whether extended register capability is supported.
0: Basic register set capabilities only
1: Extended register set capabilities
Note 13.19 The reserved bits 31-16 are used to pad the register to 32-bits so that each register is on
Note 13.20 The Virtual PHY supports 100BASE-X (half and full duplex) and 10BASE-T (half and full
Note 13.21 The Virtual PHY does not support Register 15 or 1000 Mb/s operation. Thus this bit is
