LPC Bridge (w/ System and Management Functions)
(D31:F0)
The LPC Bridge function of the ICH4 resides in PCI Device 31:Function 0. In addition to the LPC
bridge function, D31:F0 contains other functional units including DMA, 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.
LPC Interface
