1.6 Super I/O

The Super I/O (NCT6106D chip) provides four high-speed, 16550 compatible serial
communication ports (UARTs), one of which supports serial infrared communication. Each
UART includes a 128 byte send/receive FIFO, a programmable baud rate generator, complete
modem control capability, and a processor interrupt system. UARTs provide legacy speed
with a 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 support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Configuration and Power
Interface), which includes support of legacy and ACPI power management through a SMI
or SCI function pin. It also features auto power management to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can be flexibly adjusted to meet
ISA PnP requirements, which support ACPI and APM (Advanced Power Management).
