Table 14: Basic Status Register Description
The PHYs on ERTEC 200 have two registers for storage of a PHY identifier pattern; a part of this pattern
forms the upper 24 bits of the MAC address and a part of these 24 bits is given by the so-called
organizationally unique identifier (OUI).
The information in the REG2/3OUIIN registers is composed respectively interpreted as follows: NEC’s
OUI number is 003013H. This hexadecimal number is mapped into OUI format according to
Table 15.

Table 15: NEC OUI Composition
The PHY ID number however, is composed of the OUI (bits (24:3)), a 6-bit wide manufacturer model
number and a 4-bit revision number.
Table 16 shows the details.
