Ethernet PHY Identifier Register 2 - MR3 (EPHYID2)
The Ethernet PHY Identifier 1 and 2 (EPHYIDn) registers together form a unique identifier. 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 0x080028. This OUI field is broken into two fields in the EPHYID1 and EPHYID2 register. The most significant OUI field, OUIMSB in the EPHYID1 register, is equal to 0x0002 (the two most significant bits of the OUI are ignored). The least significant OUI field, OUILSB in the EPHYID2 register, is equal to 0x28.
EPHYID2 is shown in Figure 15-92 and described in Table 15-104.
