Device 2 Function 1 Configuration Register Details

(D2:F1)

10.1.1

VID2—Vendor Identification (D2:F1)

PCI Device:

Address Offset:

00h

Default Value:

8086h

Access:

Size:

16 bits

This register is a copy of Device 2, Function 0. It has the same Read, Write attributes as D2:F0. It

is implemented as common hardware with two access addresses.

10.1.2

DID2—Device Identification (D2:F1)

PCI Device:

Address Offset:

02h

Default Value:

2782h

Access:

Size:

16 bits

This register is unique in Device 2, Function 1 (the Device 2, Function 0 DID is separate). This

difference in Device ID is necessary for allowing distinct Plug and Play enumeration of function 1

when both function 0 and function 1 have the same class code.
