S5935 – PCI Product
Data Book
The VID register contains the vendor identification
number. This number is assigned by the PCI Special
Interest Group and is intended to uniquely identify any
PCI device. Write operations from the PCI interface
have no effect on this register. After reset is removed,
this field can be boot-loaded from the external non-vol-
atile device (if present and valid) so that other
legitimate PCI SIG members can substitute their ven-
dor identification number for this field.
