Fe4/FVPDR0 Vital Product Data Register 0
The register provides control and status capability for the data transfer between register Fe8/FVPDR1
and EEPROM.
BIT
ATTRIBUTE BIT NAME
DESCRIPTION

R/W
VPDFlag
VPD Flag
A flag used to indicate when the transfer of data between
the VPD Data Register (FVPDR1) and EEPROM is
completed.
A. Read VPD information
1. Reset VPDFlag to 0, and Write VPD Address to
VPDADDR.
2. VPDFlag will be set to 1, after 4 bytes data are read
from EEPROM to Register FVPDR1
B. Write VPD information
1. Write the data to Register FVPDR1.
2. Set VPDFlag to 1, and write VPD Address to
VPDADDR.
3. VPDFlag will be reset to 0, after 4 bytes data are
written from Register FVPDR1 to EEPROM.

R/W
VPDADDR VPD Address
It is used to access VPD data that is stored in EEPROM.
The lower 2 bits of VPDADDR must be zero.

NEXTID
Pointer to Next ID
Fixed at 00h. There is no next item pointer in the capabilities
list.
7:0
R
VPDID
VPD ID
Fixed at 03h. It indicates capability structure ID for VPD
Fe8/FVPDR1 Vital Product Data Register 1
The register provides the buffer for VPD from system or EEPROM.

DESCRIPTION
31:0
R/W
VPD_Data
VPD Data
VPD data are read or written through this register. The least
significant byte of this register corresponds to the byte of
VPD at the address specified by the bits VPDADDR of
register Fe4/FVPDR0.
