Architecture Overview
2.3
The Core Logic module is described in detail in Section 6.0
"Core Logic Module" on page 149.
The Core Logic module is connected to the Fast-PCI bus. It
uses signal AD28 as the IDSEL for all PCI configuration
functions except for USB which uses AD29.
2.3.1
The following interfaces of the Core Logic module are
implemented via external balls of the SC2200. Each inter-
face is listed below with a reference to the descriptions of
the relevant balls.
• IDE: See Section 3.4.9 "IDE Interface Signals" on page
• AC97: See Section 3.4.14 "AC97 Audio Interface

Core Logic Module
Other Interfaces of the Core Logic
Module
The Core Logic module interface to the GX1 module con-
sists of seven miscellaneous connections, the PCI bus
interface signals, plus the display controller connections.
Note that the PC/AT legacy signals NMI, WM_RST, and
A20M are all virtual functions executed in SMM (System
Management Mode) by the BIOS.

• SMI# is a level-sensitive interrupt to the GX1 module

2.4
The SuperI/O (SIO) module is PC98 and ACPI compliant. It
offers a single-cell solution to the most commonly used ISA
peripherals.
The SIO module incorporates: two Serial Ports, an Infrared
Communication Port that supports FIR, MIR, HP-SIR,
Sharp-IR, and Consumer Electronics-IR, a full IEEE 1284
Parallel Port, two ACCESS.bus Interface (ACB) ports, Sys-
tem Wakeup Control (SWC), and a Real-Time Clock (RTC)
that provides RTC timekeeping.
Core Logic module used to communicate power-
management states and VSYNC information for VGA
emulation.

until the SMI source is cleared.
