Three-Cable Transceiver/Arbiter Device
FW803 PHY
IEEE
1394A
Internal Register Configuration
(continued)
The vendor identification page is used to identify the PHY’s vendor and compliance level. The page is selected by
writing one to Page_select in the PHY register at address 0111
2
. The format of the vendor identification page is
shown in Table 12; reserved fields are shown shaded.
Table 12. PHY Register Page 1: Vendor Identification Page
The meaning of the register fields within the vendor identification page are defined by Table 13.
Table 13. PHY Register Vendor Identification Page Fields
The vendor-dependent page provides access to information used in manufacturing test of the FW803.

Standard to which the PHY implementation complies:
0 = not specified
1 =
IEEE
1394
a-2000
Agere’s FW803 compliance level is 1.
All other values reserved for future standardization.
The company ID or organizationally unique identifier (OUI) of the manufacturer
of the PHY. Agere’s vendor ID is 00601D
16
. This number is obtained from the
IEEE
registration authority committee (RAC). The most significant byte of
Vendor_ID appears at PHY register location 1010
2
and the least significant at
1100
2
.
The meaning of this number is determined by the company or organization that
has been granted Vendor_ID. Agere’s FW803 product ID is 081402
16
. The most
significant byte of Product_ID appears at PHY register location 1101
