Table 14. PHY Status Register (PHYSTS) Address 10h
Bit Bit Name Default Description
15 Receive Error Latch 0, RO/L Receive Error Latch:
1 = Receive error event has occurred since last read of RXER-
CNT
0 = No receive error event has occurred
14 CIM Latch 0, RO/L Carrier Integrity Monitor Latch:
1 = Carrier Integrity Monitor has found an isolate event since last
read of DCR
0 = No Carrier Integrity Monitor isolate event has occurred
13 False Carrier Sense
Latch
0, RO/L False Carrier Sense Latch:
1 = False Carrier event has occurred since last read of FCSCR
0 = No False Carrier event has occurred
12 Reserved 0, RO Reserved: Write ignored, read as 0.
11 Device Ready 0, RO Device Ready:
This bit signifies that the device is now ready to transmit data.
1 = Device Ready
0 = Device not Ready
10 Page Received 0, RO/L Link Code Word Page Received:
This bit is set when a new Link Code Word Page has been re-
ceived. Cleared on read of the ANER register.
9 Auto-Negotiation En-
abled
Strap, RO Auto-Negotiation Enabled:
1 = Auto-Negotiation Enabled.
0 = Auto-Negotiation Disabled.
8 MII Interrupt 0, RO/L MII Interrupt Pending:
Indicates that an internal interrupt is pending and is cleared by the
current read. A read of this bit will clear the bit in the MIPGSR
(12h) also.
7 Remote Fault 0, RO/L Remote Fault:
1 = Remote Fault condition detected (cleared on read of BMSR
register or by a chip reset). Fault criteria is Far end Fault Isolation
or notification from Link Partner of Remote Fault.
0 = No remote fault condition detected
6 Jabber Detect 0, RO/L Jabber Detect:
1 = Jabber condition detected
0 = No Jabber
This bit is implemented with a latching function so that the occur-
rence of a jabber condition causes it to become set until it is
cleared by a read to the BMSR register by the management inter-
face or by a Device reset. This bit only has meaning in 10 Mb/s
mode.
5 NWAY Complete 0, RO Auto-Negotiation Complete:
1 = Auto-Negotiation complete
0 = Auto-Negotiation not complete
4 Reset Status 0, RO Reset Status:
0 = Normal operation
1 = Reset in progress
