ICS1893AF Data Sheet - Release  
Chapter 8 Management Register Set  
8.4 Register 2: PHY Identifier Register  
Table 8-7 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 8.5, “Register 3: PHY Identifier Register”  
Manufacturer’s PHY Revision Number, discussed in Section 8.5, “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  
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”.
