2. RxRef, =1 when this interface supports the RxRefB UTOPIA signal.
3. TxClav, =1 when this interface supports the TxClav UTOPIA signal.
4. RxClav, =1 when this interface supports the RxClav UTOPIA signal.
5. TxXon, =1 when this interface supports the TxXon UTOPIA signal.
6. Ver[3:0], 4 bits UTOPIA version number, value for this specification =1.
7. D16, =1 to indicate 16-bit datapath, 0 = 8-bit datapath.
8. HEC, =1 to indicate the HEC is carried in the UDF(1) field.
9. HCS, =1 to indicate HCS is carried in the UDF(2) field, for 16-bit mode
only.

64 or 48-bit Address:
Contains eight octets which define the 64 or 48-bit address of the PHY interface.
If a 48-bit address is used, the 2 most significant octets are zero filled. The
address is stored in Big-Endian format (MSB is in the LS address). The SAPI-
UTP5 board has 0x00 programmed into this location.
Reserved:
Reserved for future expansion.
Manufacturer ID, etc.:
Contains sixteen octets which identify the manufacturer of the PHY interface.
Using the ASCII character set (7-bit code) is encouraged. Three octets of ASCII
representing the manufacture ID and 13 octets of part number.
