NAME    [Toc]    [Back]

     gscsio - National Semiconductor Geode SC1100 Super I/O

SYNOPSIS    [Toc]    [Back]

     gscsio* at isa?

DESCRIPTION    [Toc]    [Back]

     The gscsio driver provides support for the National Semiconductor Geode
     SC1100 System-on-Chip Super I/O module.  The Super I/O (SIO)
module incorporates
 one serial port, an infrared communication  port,
two ACCESS.bus
 interface (ACB) ports, system wakeup control (SWC),
and a realtime
 clock (RTC).  Only the ACCESS.bus interface is currently supported.

     ACB  is  a  two-wire synchronous serial interface compatible
with the
     Philips' I2C bus, and can be  accessed  through  the  iic(4)
framework.  The
     gscsio  driver programs the ACB port to work with a standard
I2C frequency

HISTORY    [Toc]    [Back]

     The gscsio driver first appeared in OpenBSD 3.6.
