1-6 Super I/O

The Super I/O provides two high-speed, 16550 compatible serial communication

ports (UARTs). Each UART includes a 16-byte send/receive FIFO, a programmable

baud rate generator, complete modem control capability and a processor interrupt

system. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as

well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which sup-

port higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Conguration

and Power Interface), which includes support of legacy and ACPI power manage-

ment through a SMI or SCI function pin. It also features auto power management

to reduce power consumption.
