6.4 PHY ID Identifier Register 1 (042h, 062h)
The PHY Identifier Registers #1 and #2 work together in a single identifier of the DM8603. 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.
6.5 PHY ID Identifier Register 2 (043h, 063h)

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)
