Description
This register is reserved for the manufacturer’s device
identification number (DID). DID numbers are main-
tained and issued by the registered owner of the VID
number programmed into a PCI device. AMCC will
issue a DID number to manufacturers using the AMCC
VID. This maintains PCI device uniqueness among all
manufacturers. to be in compliance. This register
defaults to AMCC's DID during power-on initialization.
The default value can be changed to another valid DID
when an external nonvolatile device is used for boot
loading.
