PRODUCTION DATA.
The PHY Identifier Registers #1 and #2 together form a unique identifier for the DP83848-EP. The Identifier consists of a concatenation of the Organizationally Unique Identifier (OUI), the vendor's model number and the model revision number. A PHY may return a value of zero in each of the 32 bits of the PHY Identifier if desired. The PHY Identifier is intended to support network management. National's IEEE assigned OUI is 080017h.
BIT | BIT NAME | DEFAULT | DESCRIPTION |
---|---|---|---|
15:0 | OUI_MSB | <0010 0000 0000 0000>, RO/P | OUI Most Significant Bits: Bits 3 to 18 of the OUI (080017h) are stored in bits 15 to 0 of this register. The most significant two bits of the OUI are ignored (the IEEE standard refers to these as bits 1 and 2). |
