that are part of a set defined by the ISO/IEC specification. This register stores the following:
•
•
•
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:
Table 8-9.
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.
