[1] Reset hex values that are highlighted (for example, 0) indicate read/write access, and reset hex values that are not highlighted (for

example, 0) indicate read-only.

[2] XX is 1FH for four ports or 07H for two ports.

The Host Controller Driver (HCD) does not usually interact with the PCI configuration

space. The configuration space is used only by the PCI enumerator to identify the

USB Host Controller and assign the appropriate system resources by reading the

Vendor ID (VID) and the Device ID (DID).

8.2.1 PCI configuration header registers

The Enhanced Host Controller implements the normal PCI header register values,

except the values for the memory-mapping base address register, serial bus number

and Device ID.

Vendor ID register (address: 00H): This read-only register identifies the

manufacturer of the device. PCI Special Interest Group (PCI-SIG) assigns valid

vendor identifiers to ensure the uniqueness of the identifier. The bit description is

shown in Table 4.

15 to 0 VID[15:0] R

1131H

Vendor ID: This read-only register value is

assigned to Philips Semiconductors by PCI-SIG

as 1131H.

Device ID register (address: 02H): Device ID is a two-byte read-only register that

identifies a particular device. This identifier is allocated by Philips Semiconductors.

Table 5 shows the bit description of the register.
