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:
•
•
•
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
Register Override bit (bit 16.15) is enabled with a logic one.
