82801EB ICH5 / 82801ER ICH5R Datasheet
Note: Address locations that are not shown in
The LPC Bridge function of the ICH5 resides in PCI Device 31:Function 0. This function contains
many other functional units (e.g., 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.
