DESCRIPTION
8 Page
Received
0,RO
Link Code Word Page Received:
1 = A new Link Code Word Page has been received. This bit is a duplicate of Page Received (bit 1)
in the ANER register and it is cleared on read of the ANER register (0x0006).
0 = Link Code Word Page has not been received.
This bit will not be cleared upon a read of the PHYSTS register.
7 MII Interrupt 0,RO
MII Interrupt Pending:
1 = Indicates that an internal interrupt is pending. Interrupt source can be determined by reading the
MISR Register (0x0012). Reading the MISR will clear this Interrupt bit indication.
0 = No interrupt pending
6 Remote Fault 0,RO
Remote Fault:
1 = Remote Fault condition detected. Fault criteria: notification from Link Partner of Remote Fault
via Auto-Negotiation. Cleared on read of BMSR register (0x0001) or by reset.
0 = No remote fault condition detected
5 Jabber Detect 0,RO
Jabber Detect:
1 = Jabber condition detected. This bit has meaning only in 10 Mb/s mode. This bit is a duplicate of
the Jabber Detect bit in the BMSR register (0x0001).
0 = No Jabber
This bit will not be cleared upon a read of the PHYSTS register.
4 Auto-Neg
Status
0,RO
Auto-Negotiation Status:
1 = Auto-Negotiation complete
0 = Auto-Negotiation not complete
3 MII Loopback 0,RO
Status
MII Loopback:
1 = Loopback active (enabled)
0 = Normal operation
2 Duplex Status 0,RO
Duplex Status:
1 = Full duplex mode
0 = Half duplex mode
This bit indicates duplex status and is determined from Auto-Negotiation or Forced Modes. Therefore, it
is only valid if Auto-Negotiation is enabled and complete and there is a valid link or if Auto-Negotiation
is disabled and there is a valid link.
1 Speed Status 0,RO
Speed Status:
1 = 10 Mb/s mode
0 = 100 Mb/s mode
This bit indicates the status of the speed and is determined from Auto-Negotiation or Forced Modes.
Speed Status is only valid if Auto-Negotiation is enabled and complete and there is a valid link or if
Auto-Negotiation is disabled and there is a valid link.
0 Link Status 0,RO
Link Status:
1 = Valid link established (for either 10 or 100 Mb/s operation). This bit is a duplicate of the Link
Status bit in the BMSR register (0x0001).
0 = Link not established
This bit will not be cleared upon a read of the PHYSTS register.
