ICH7 Family Datasheet
LPC Interface Bridge Registers
(D31:F0)
The LPC bridge function of the ICH7 resides in PCI Device 31:Function 0. This function
contains many other functional units, such as DMA and Interrupt controllers, Timers,
Power Management, System Management, GPIO, RTC, and LPC Configuration
Registers.
Registers and functions associated with other functional units (EHCI, UHCI, IDE, etc.)
are described in their respective sections.
