HS USB PCI Host Controller
7.6 Power management
The ISP1561 provides an advanced power management capabilities interface that is
compliant with Ref. 5 “PCI Bus Power Management Interface Specication”. Power is
controlled and managed by the interaction between drivers and PCI registers. For a
detailed description on power management, see Section 10.
7.7 Legacy support
The ISP1561 provides legacy support for a USB keyboard and mouse. This means that
the keyboard and mouse must be able to work even before the OS boot-up, with the
necessary support in the system’s BIOS. Section 11.2 provides detailed description on
legacy support in the ISP1561.
7.8 Phase-Locked Loop (PLL)
A 12 MHz-to-30 MHz and 48 MHz clock multiplier PLL is integrated on-chip. This allows
the use of a low-cost 12 MHz crystal, which also minimizes EMI. No external components
are required for the PLL to operate.

PCI
8.1 PCI interface
The PCI interface has three functions. The rst 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 supports both master and target accesses and share the same PCI interrupt
signal INTA#. These functions provide memory-mapped, addressable operational
registers as required in Ref. 4 “Open Host Controller Interface Specication for USB” and
Additionally, function #0 provides legacy keyboard and mouse support to comply with Ref.
Each function has its own conguration space. The PCI enumerator must allocate the
memory address space for each of these functions. Power management is implemented
in each PCI function and all power states are provided. This allows the system to achieve
low power consumption by switching off the functions which are not required.
8.1.1 PCI conguration space
Ref. 6 “PCI Local Bus Specication” requires that each of the three PCI functions of the
ISP1561 provides its own PCI conguration registers, which can vary in size. In addition to
the basic PCI conguration header registers, these functions implement the capability
registers to support power management.
The registers of each of these functions are accessed by the respective driver. Section 8.2
provides a detailed description of various PCI conguration registers.
