The PHY Identifier Registers #1 and #2 together form a unique identifier for the DP83848YB. The Identifier consists of a
concatenation of the Organizationally Unique Identifier (OUI), the vendor's model number and the model revision num-
ber. 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.
7.1.3 PHY Identifier Register #1 (PHYIDR1)
7.1.4 PHY Identifier Register #2 (PHYIDR2)
7.1.5 Auto-Negotiation Advertisement Register (ANAR)
This register contains the advertised abilities of this device as they will be transmitted to its link partner during Auto-Nego-
tiation.

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).

Model Revision Number:
Four bits of the vendor model revision number are mapped from
bits 3 to 0 (most significant bit to bit 3). This field will be incremented
for all major device changes.
