Default
100BASE-T4. This protocol is not supported. This register
bit is always set to 0b.
0b = Not 100BASE-T4 capable.
1b = 100BASE-TX full duplex capable.
0b = Not 100BASE-TX full duplex capable.
1b = 100BASE-TX half duplex capable.
0b = Not 100BASE-TX half duplex capable.
1b = 10BASE-T full duplex capable.
0b = Not 10BASE-T full duplex capable.
1b = 10BASE-T half duplex capable.
0b = Not 10BASE-T half duplex capable.
Not able to perform 100BASE-T2.
Not able to perform 100BASE-T2.
Extended status information in the register Extended
Status (0xF).
Must always be set to 0b.
1b = PHY accepts management frames with preamble
suppressed.
This bit is set after auto-negotiation completes.
1b = Auto-negotiation process complete.
0b = Auto-negotiation process not complete.
This bit indicates that a remote fault has been detected.
Once set, it remains set until it is cleared by reading
register 1 via the management interface or by PHY reset.
1b = Remote fault condition detected.
0b = Remote fault condition not detected.
1b = PHY able to perform auto-negotiation.
0b = PHY not able to perform auto-negotiation.
This bit indicates that a valid link has been established.
Once cleared, due to link failure, this bit remains cleared
until register 1 is read via the management interface.
1b = Link is up.
0b = Link is down.
1b = Jabber condition detected.
0 = Jabber condition not detected.
Indicates that the PHY provides an extended set of
capabilities that might be accessed through the extended
register set. For a PHY that incorporates a GMII/RGMII,
the extended register set consists of all management
registers except registers 0, 1, and 15.
1b = Extended register capabilities.
