Description
Returns 0 when read. Reset to 0
VPD address for read / write cycle
Returns 0 when read. Reset to 0
Writing a 0 to this bit generates a read cycle from the EEPROM at the
VPD address specified in bits[7:2] of this register. This bit remains 0
until EEPROM cycle is finished, after which it will be set to 1. Data for
reads are available at offset ECh.
Writing a 1 to this bit generates a write cycle to the EEPROM at the VPD
address specified in bits[7:2] of this register. This bit remains at 1 until
EEPROM cycle is finished, after which it will be cleared to 0.
Reset 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 from or
written to this register uses the normal PCI byte transfer capabilities.
