7.4 Register 2: PHY Identifier Register

Table 7-7 lists the bits for PHY Identifier Register (Register 2), which is one of two PHY Identifier Registers

that are part of a set defined by the ISO/IEC specification. As a set, the PHY Identifier Registers (Registers

2 and 3) include a unique, 32-bit PHY Identifier composed from the following:

• Organizationally Unique Identifier (OUI), discussed in this section

• Manufacturer’s PHY Model Number, discussed in Section 7.5, “Register 3: PHY Identifier Register”

• Manufacturer’s PHY Revision Number, discussed in Section 7.5, “Register 3: PHY Identifier Register”

All of the bits in the two PHY Identifier Registers are Command Override Write bits. An STA can read them

at any time without condition. However, an STA can modify these register bits only when the Command
