Some of the Super I/O features are described in more detail below:
2.8.3.1 Super I/O LPC Interface
The LPC interface on the Super I/O complies with the 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 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
2.8.3.3 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.
