ANR2 and ANR3: PHY Identifier (Registers 2 and 3)
Registers 2 and 3 contain a unique PHY identifier, con-
sisting of 22 bits of the organizationally unique IEEE
Identifier, a 6-bit manufacturer’s model number, and a
4-bit manufacturer’s revision number. The most signifi-
cant bit of the PHY identifier is bit 15 of register 2; the
least significant bit of the PHY identifier is bit 0 of reg-
ister 3. Register 2, bit 15 corresponds to bit 3 of the

Description
IEEE Identifier and register 2, bit 0 corresponds to bit
18 of the IEEE Identifier. Register 3, bit 15 corresponds
to bit 19 of the IEEE Identifier and register 3, bit 10 cor-
responds to bit 24 of the IEEE Identifier. Register 3, bits
9-4 contain the manufacturer’s model number and bits
3-0 contain the manufacturer’s revision number. These
registers are shown in Table 42 and Table 43.
