Extended Capability
1 = Extended register capable
capability
0 = Basic register capable only
8.3 PHY ID Identifier Register #1 (PHYID1) - 02
The PHY Identifier Registers #1 and #2 work together in a single identifier of the DM9008C. 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.
Bit
2.15-2.0
Bit Name
OUI_MSB
Default
<0181h>
Description
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)
8.4 PHY ID Identifier Register #2 (PHYID2) - 03
Bit
Bit Name
3.15-3.10 OUI_LSB
3.9-3.4 VNDR_MDL
3.3-3.0 MDL_REV
Default
<101110>,
RO/P
<001011>,
RO/P
<0000>,
RO/P
Description
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)
8.5 Auto-negotiation Advertisement Register (ANAR) - 04
This register contains the advertised abilities of this DM9008C device as they will be transmitted to its link partner
during Auto-negotiation.
Bit
Bit Name
4.15

Default
0,RO/P
0,RO
0, RW
Description
Next page Indication
0 = No next page available
1 = Next page available
The DM9008C has no next page, so this bit is permanently set to 0
Acknowledge
1 = Link partner ability data reception acknowledged
0 = Not acknowledged
The DM9008C's auto-negotiation state machine will automatically
control this bit in the outgoing FLP bursts and set it at the
appropriate time during the auto-negotiation process. Software
should not attempt to write to this bit.
Remote Fault
1 = Local device senses a fault condition
0 = No fault detected
