IEEE-Assigned Organizationally Unique Identifier (OUI)
For each manufacturing organization, the IEEE assigns an 3-octet OUI. For Integrated Circuit Systems,
Inc. the IEEE-assigned 3-octet OUI is 00A0BEh.
The binary representation of an OUI is formed by expressing each octet as a sequence of eight bits, from
least significant to most significant, and from left to right. Table 7-8 provides the ISO/IEC-defined mapping
of the OUI (in IEEE Std. 802-1990 format) to Management Registers 2 and 3.
7.5 Register 3: PHY Identifier Register
Table 7-9 lists the bits for PHY Identifier Register (Register 3), which is one of two PHY Identifier Registers
that are part of a set defined by the ISO/IEC specification. This register stores the following:
Manufacturer’s PHY Model Number
Manufacturer’s PHY Revision Number
All 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
Register Override bit (bit 16.15) is enabled with a logic one.
Note: For an explanation of acronyms used in Table 7-5, see Chapter 1, “Abbreviations and Acronyms”.
