82801DB ICH4 Datasheet
Note: Registers that are not shown should be treated as Reserved (See
The LPC Bridge function of the ICH4 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 (USB UHCI, USB EHCI, IDE, etc.)
are described in their respective sections.
