Description
Device ID (Default: 0x0184/0x0185)
This register indicates the ID that is allocated to a device. The ID can be
changed by loading data from a configuration EEPROM during initialization.
PCIC (external PCI bus controller) = 0x0184
PCIC1(internal PCI bus controller) = 0x0185
Vendor ID (Default: 0x102F)
This register indicates the device product that is allocated by PCI SIG.
