8.3 PHY ID Identifier Register #1 (PHYID1) – 02H
The PHY Identifier Registers #1 and #2 work together in a single identifier of the DM9332. 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 ID Identifier Register #2 (PHYID2) – 03H

10/100Mbps Ethernet Fiber/Twisted Pair Single Chip Media Converter
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 cleared 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 DM9332 reset. This bit works only in
10Mbps mode
Extended Capability
1 = Extended register capable
0 = Basic register capable only
OUI Most Significant Bits
This register stores bit 3 to 18 of the OUI (00606E) 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
Five bits of vendor model number mapped to bit 9 to 4 (most
significant bit to bit 9)
Model Revision Number
Five bits of vendor model revision number mapped to bit 3 to 0
(most significant bit to bit 4)
