0: Generate a read cycle from the EEPROM at the VPD address specified in
bits [7:2] of offset D8h. This bit remains at ‘0’ until EEPROM cycle is
finished, after which the bit is then set to ‘1’. Data for reads is available at
register ECh.
1: Generate a write cycle to the EEPROM at the VPD address specified in
bits [7:2] of offset D8h. This bit remains at ‘1’ until EEPROM cycle is
finished, after which it is then cleared to ‘0’.

DESCRIPTION
VPD Data (EEPROM data [address + 0x40])
The least significant byte of this register corresponds to the byte of VPD at
the address specified by the VPD address register. The data read form or
written to this register uses the normal PCI byte transfer capabilities.
