HS USB PCI Host Controller
8.2.1.1 Vendor ID register
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.

to Philips Semiconductors by PCI-SIG as 1131h.
8.2.1.2 Device ID register
This is a 2 B read-only register that identifies a particular device. The identifier is allocated
by Philips Semiconductors. Table 5 shows the bit description of the register.

156Xh* [1] Device ID: This register value is defined by Philips
Semiconductors to identify the USB Host Controller
IC product.
[1] X is 1h for OHCI1 and OHCI2; X is 2h for EHCI.
8.2.1.3 Command register
This is a 2 B register that provides coarse control over the ability of a device to generate
and respond to PCI cycles. The bit allocation of the Command register is given in Table 6.
When logic 0 is written to this register, the device is logically disconnected from the PCI
bus for all accesses, except configuration accesses. All devices are required to support
this base level of functionality. Individual bits in the Command register may or may not
support this base level of functionality.
