Data Sheet
Device Identification Register (DID)
The DID register contains the vendor-assigned device
identification number. This number is generated by
AMCC in compliance with the conditions of the PCI
specification. 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 own
device identification number for this field.
