Register 3: PHY Identifier Register
Table 8-9 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 8-5, see Chapter 1, “Abbreviations and Acronyms”.
8.5.1
OUI bits 19-24 (bits 3.15:10)
The most-significant 6 bits of register 3 (that is, bits 3.15:10) include OUI bits 19 through 24. OUI bit 19 is
stored in bit 3.15, while OUI bit 24 is stored in bit 3.10.
