The Subsystem Vendor ID register is used to uniquely identify the expansion board or
subsystem where the PCI device resides. This register allows expansion board vendors to
distinguish their boards, even though the boards may have the same Vendor ID and
Device ID.
Subsystem Vendor IDs are assigned by PCI-SIG to maintain uniqueness. The bit
description of the Subsystem Vendor ID register is given in
Table 18:

Subsystem ID values are vendor specific. The bit description of the Subsystem ID register
is given in

This register is used to point to a linked list of new capabilities implemented by the device.
This register is only valid if CL (bit 4 in the Status register) is set. If implemented, bit 1 and
bit 0 are reserved and should be set to 00b. Software should mask these bits off before
using this register as a pointer in configuration space to the first entry of a linked list of
new capabilities. The bit description of the register is given in

Description
Subsystem Vendor ID: 1131h is the subsystem
Vendor ID assigned to Philips Semiconductors.
Description
Base Address to Memory-Mapped Host
Controller Register Space: The memory size
required by OHCI and EHCI are 4 kB and 256 B,
respectively. Therefore, BAR 0[31:12] is assigned to
the two OHCI ports, and BAR 0[31:8] is assigned to
the EHCI port.
Description
Subsystem ID: For the ISP1563, Philips
Semiconductors has defined OHCI functions as
1561h, and the EHCI function as 1562h.
