PHY Identifier Register (register 2 [0x02])
PHY Identifier Register (register 2)
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.
Organizationally Unique Identifier bits 3-18 (bits
15-0)
This field contains the lowest 16 bits of the IEEE OUI excluding
OUI maps to bit 15 of the register.
OUI Formatting Information The ICS OUI is shown
below with information on mapping the OUI value into registers
2 and 3.
