8.5

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:

• Part of the OUI [see the text in Section 8.4, “Register 2: PHY Identifier Register”]

• Manufacturer’s PHY Model Number

• Manufacturer’s PHY Revision Number

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

Note:

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.

8.5.2

Manufacturer's Model Number (bits 3.9:4)

The model number for the ICS1892 is 3 (decimal). It is stored in bit 3.9:4 as 00011b.
