8.1.3 PHY Identifier Register 1 (PHYIDR1)
The PHY Identifier Registers 1 and 2 together form a unique identifier for the TLK10x. The identifier
consists of a concatenation of the Organizationally Unique Identifier (OUI), the vendor's model number
and the model revision number. A PHY may return a value of zero in each of the 32 bits of the PHY
Identifier if desired. The PHY Identifier is intended to support network management. The Texas
Instruments IEEE-assigned OUI is 080028h, implemented as Reg 0x2 [15:0] = OUI[21:6] = 2000(h) and
Reg 0x3 [15:10] = OUI[5:0] = A(h).

DESCRIPTION
OUI[21:6] = 2000(h): The most significant two bits of the OUI are ignored (the IEEE
standard refers to these as bits 1 and 2).

DESCRIPTION
Vendor Model Number:
The six bits of vendor model number are mapped from bits 9 to 4 (most significant bit to bit 9).
Model Revision Number:
Four bits of the vendor model revision number are mapped from bits 3 to 0 (most significant bit to
bit 3). This field is incremented for all major device changes.
