PHY Identifier Register (register 3
[0x03]
)
PHY Identifier Register (register 3)
Register 2 and Register 3 contain the 24 bit Organizationally
Unique Identifier (OUI), Manufacturers Model Number and
Revision Number. Integrated Circuit Systems OUI is used as
the default for registers 2 and 3.
These two registers can always be read and may be written by
setting the Command Override bit in the Configuration register
(16:15) and then performing a write operation. At power-up
and reset they are set to Integrated Circuit Systems OUI. By
allowing these registers to be written, a systems vendor may
substitute their own OUI.
See register 2 for OUI formatting information.
Organizationally Unique Identifier bits 19-24 (bits
15-10)
This field contains the upper 6 bits of the IEEE OUI. Bit 19 of
the OUI maps to bit 15 of the register.
Manufacturers Model Number bits 5-0 (bits 9-4)

Revision Number bits 3-0 (bits 3-0)
The revision number will be incremented each time the silicon
is significantly revised. Currently the device is at revision 2.
