Some of the Super I/O features are described in more detail below:
2.7.3.1 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.
2.7.3.2 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
Another two chipsets connected to the LPC bus provided connectivity to another two serial
port connectors (COM3 and COM4).
