2.6.3.1 Super I/O LPC Interface

The LPC interface on the Super I/O complies with the Intel

®

Low Pin Count Specification

Rev. 1.0. The LPC interface supports both LDRQ# and SERIRQ protocols as well as PCI

PME# interfaces.

2.6.3.2 Super I/O 16C550 UARTs

The onboard Super I/O has two integrated 16C550 UARTs that can support the following:

Two standard serial ports (COM1 and COM2)

IrDa 1.0 and ASKIR protocols

2.6.3.3 Super I/O Digital Input/Output

The input mode supports switch debouncing or programmable external IRQ routing. The

output mode supports two sets of programmable LED blinking periods.

2.6.3.4 Super I/O Enhanced Hardware Monitor

The Super I/O Enhanced Hardware Monitor monitors two thermal inputs, VBAT internally,

and eight voltage monitor inputs. These hardware parameters are reported in the BIOS

and can be read from the BIOS Hardware Health Configuration menu.

2.6.3.5 Super I/O Fan Speed Controller

The Super I/O fan speed controller enables the system to monitor the speed of the fan.

One of the pins on the fan connector is reserved for fan speed detection and interfaced to

the fan speed controller on the Super I/O. The fan speed is then reported in the BIOS.

2.6.3.6 Super I/O Keyboard/Mouse Controller

The Super I/O keyboard/mouse controller can execute the 8042 instruction set. Some of

the keyboard controller features are listed below:

The 8042 instruction is compatible with a PS/2 keyboard and PS/2 mouse

Gate A20 and Keyboard reset output

Supports multiple keyboard power on events

Supports mouse double-click and/or mouse move power on events
