Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk drive
controller compatible with industry standard 82077/765, a data separator, write
pre-compensation circuitry, decode logic, data rate selection, a clock generator,
drive interface control logic and interrupt and DMA logic. The wide range of
functions integrated into the Super I/O greatly reduces the number of compo-
nents required for interfacing with floppy disk drives. The Super I/O supports four
360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250
Kb/s, 500 Kb/s or 1 Mb/s.
It also provides two high speed serial communication ports (UARTs), one of which
supports serial infrared communication. 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 rates of up to 115.2 Kbps as well as an advanced speed with baud rates
of 230 K, 500 K or 1 Mb/s, which support higher speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port
(ECP). Extension FDD and Extension 2FDD Modes are also available through
the printer port interface pins to allow one or two external floppy disk drives to
be connected.
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through SMI or SCI function pins. It also features auto power management
to reduce power consumption.
The Super I/O complies with the Microsoft PC98 Hardware Design Guide.
IRQs, DMAs and I/O space resources can flexibly adjust to meet ISA PnP
requirements. Moreover, it meets the specification of PC98's power management
requirement: ACPI and APM (Advanced Power Management).
