Status Register: Register 1
Identification Registers: Registers 2 and 3
The 32-bit ID register provides a mechanism for software to determine which PHY is present. The
contents of these registers differ depending on the PHY. There are three values encoded in registers
2 and 3 that uniquely identify the PHY device:
The OUI is a 24-bit manufacturer identification number. Only the least significant 22 bits of the
OUI are stored in the registers. The two most significant bits, bits 23:22, are fixed at 0. Bits 21:6 of
the OUI are stored in register 2 while the remaining bits of the OUI, bits 5:0, are stored in bits
15:10 of register 3. (The Intel manufacturer OUI number is “00AA00h.”)
The model number is a 6-bit value assigned by the manufacturer identifying the PHY model. It is
stored in bits 9:4 of register 3. (The Intel PHY model number is “010101.”)
