Product data sheet
8.1 PCI interface
The PCI interface has three functions. The first function (#0) and the second function (#1)
are for OHCI Host Controllers, and the third function (#2) is for the EHCI Host Controller.
All functions support both master and target accesses, and share the same PCI interrupt
signal INTA#. These functions provide memory-mapped, addressable operational
registers as required in Open Host Controller Interface Specification for USB Rev. 1.0a
and Enhanced Host Controller Interface Specification for Universal Serial Bus Rev. 1.0 .
