8.1.3 PHY Identifier Register #1 (PHYIDR1)
The PHY Identifier Registers #1 and #2 together form a unique identifier for the TLK110. 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.

DESCRIPTION
OUI Most Significant Bits: Bits 3 to 18 of the OUI (080028h) are stored in bits 15 to 0 of
this register. The most significant two bits of the OUI are ignored (the IEEE standard refers
to these as bits 1 and 2).

OUI Least Significant Bits:
DESCRIPTION
Bits 19 to 24 of the OUI (080028h) are mapped from bits 15 to 10 of this register respectively.
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.
