IEEE-Assigned Organizationally Unique Identifier (OUI)
7.5 Register 3: PHY Identifier Register
ICS1893CK-40, Rev. C, 06/02/09
For each manufacturing organization, the IEEE assigns an 3-octet OUI. For Integrated Circuit Systems,
Inc. the IEEE-assigned 3-octet OUI is 00A0BEh. This OUI is retained for backwards compatibility with older
versions of the ICS1893.
The binary representation of an OUI is formed by expressing each octet as a sequence of eight bits, from
least significant to most significant, and from left to right.
of the OUI (in IEEE Std. 802-1990 format) to Management Registers 2 and 3.

that are part of a set defined by the ISO/IEC specification. This register stores the following:

•
All 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
Register Override bit (bit 16.15) is enabled with a logic one.
