2.8.3.1 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.
2.8.3.2 Super I/O 16C550 UARTs
The on-board 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
Another two chipsets connected to the LPC bus provided connectivity to another two serial
port connectors (COM3 and COM4).
2.8.3.3 Super I/O Enhanced Hardware Monitor
The Super I/O Enhanced Hardware Monitor monitors three 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.
2.8.3.4 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.
2.8.3.5 Super I/O Keyboard Controller
The Super I/O keyboard 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
