307013-003 Datasheet, PDF (118/848 Pages) Intel Corporation – Intel I/O Controller Hub 7

Functional Description
5.4.3
Note:
ASF Software Support
ASF requires software support to make a complete solution. The following software is
used as part of the complete solution.
• ASF Configuration driver / application
• Network Driver
• BIOS Support for SMBIOS, SMBus ARP, ACPI
• Sensor Configuration driver / application
Contact your Intel Field Representative for the Client ASF Software Development Kit
(SDK) that includes additional documentation and a copy of the client ASF software
drivers. Intel also provides an ASF Console SDK to add ASF support to a management
console.

LPC Bridge (w/ System and Management
Functions) (D31:F0)
Note:
LPC DMA is not supported on the Ultra Mobile component (ICH7-U).
The LPC bridge function of the ICH7 resides in PCI Device 31:Function 0. In addition to
the LPC bridge function, D31:F0 contains other functional units including DMA (Desktop
and Mobile only), Interrupt controllers, Timers, Power Management, System
Management, GPIO, and RTC. In this chapter, registers and functions associated with
other functional units (power management, GPIO, USB, IDE, etc.) are described in their
respective sections.
5.5.1 LPC Interface
The ICH7 implements an LPC interface as described in the Low Pin Count Interface
Specification, Revision 1.1. The LPC interface to the ICH7 is shown in Figure 5-3. Note
that the ICH7 implements all of the signals that are shown as optional, but peripherals
are not required to do so.
