8.3 PHY ID Identifier Register #1 (PHYID1) - 02
The PHY Identifier Registers #1 and #2 work together in a single identifier of the DM9000. The Identifier consists
of a concatenation of the Organizationally Unique Identifier (OUI), a vendor's model number, and a model
revision number. DAVICOM Semiconductor's IEEE assigned OUI is 00606E
8.4 PHY Identifier Register #2 (PHYID2) - 03

0,
0 = Link is not established
The link status bit is implemented with a latching function, so that the
occurrence of a link failure condition causes the link status bit to be,
and remain cleared until it is read via the management interface
Jabber Detect
1 = Jabber condition detected
0 = No jabber
This bit is implemented with a latching function. Jabber conditions
will set this bit unless it is cleared by a read to this register through a
management interface or a PHY reset. This bit works only in 10Mbps
mode
Extended Capability
1 = Extended register capable
0 = Basic register capable only
OUI Most Significant Bits
Bit 3 to 18 of the OUI (00606E) are mapped to bit 15 to 0 of this
register respectively. The most significant two bits of the OUI are
ignored (the IEEE standard refers to these as bit 1 and 2)
OUI Least Significant Bits
Bit 19 to 24 of the OUI (00606E) are mapped to bit 15 to 10 of this
register respectively
Vendor Model Number
Six bits of vendor model number mapped to bit 9 to 4 (most
significant bit to bit 9)
Model Revision Number
Four bits of vendor model revision number mapped to bit 3 to 0
(most significant bit to bit 3)
