HS USB PCI Host Controller
[1]
Reset values that are highlighted (for example, 0) indicate read and write accesses; and reset values that are not highlighted (for
example, 0) indicate read-only.
[2]
XX is 1Fh for four ports or 07h for two ports.
The HCD does not usually interact with the PCI conguration space. The conguration
space is used only by the PCI enumerator to identify the USB Host Controller and assign
appropriate system resources by reading the Vendor ID (VID) and the Device ID (DID).
8.2.1 PCI conguration header registers
The enhanced Host Controller implements normal PCI header register values, except the
values for the memory-mapping base address register, serial bus number and device ID.
8.2.1.1
Vendor ID register (address: 00h)
This read-only register identies the manufacturer of the device. PCI Special Interest
Group (PCI-SIG) assigns valid vendor identiers to ensure the uniqueness of the
identier. The bit description is shown in Table 4.
8.2.1.2
Device ID register (address: 02h)
Device ID is a 2-byte read-only register that identies a particular device. This identier is
allocated by NXP Semiconductors. Table 5 shows the bit description of the register.
[1]
X is 1561h for OHCI1 and OHCI2 and X is 1562h for EHCI.
