15:0 Organizationally

Unique Identifier

(bits 3:18)

Read/Write 001Ah This identifier is assigned to PHY manufacturers by

the IEEE. Its intention is to provide sufficient informa-

tion to support 10/100 Management as defined in

Clause 30.1.2 of the IEEE 802.3 specification.

This register contains bits [3:18] of the OUI. Bit 3 of

the OUI is located in bit 15 of the PHY Identifier, bit 4

of the OUI is in bit 14, and so on.

Note: This field is disabled, and writes to this bit are

ignored when the National Compatibility Mode bit of

the 10BASE-T Configuration Register (address 1Ch)

is set.
