# NAME

`nsclpcsio` — National Semiconductor PC87366 LPC Super I/O with GPIO

# SYNOPSIS

`nsclpcsio* at isa?`
`gpio* at nsclpcsio?`

# DESCRIPTION

The `nsclpcsio` driver provides support for the National Semiconductor PC87366 LPC Super I/O. The Super I/O module incorporates several logical devices, the following ones are supported: GPIO, VLM and TMS.

The GPIO logical device provides 29 I/O pins which can be accessed through the gpio(4) framework. The gpioctl(8) program allows easy manipulation of the pins from userland.

VLM and TMS logical devices provides hardware monitoring capabilities to be used with the sysctl(8) interface. The following 17 monitoring sensors are available:

Sensor | Units | Typical Use
`TSENS1` | uK | Remote diode
`TSENS2` | uK | Remote diode
`TNSC` | uK | Local diode
`VSENS0` | uV DC | External source
`VSENS1` | uV DC | External source
`VSENS2` | uV DC | External source
`VSENS3` | uV DC | External source
`VSENS4` | uV DC | External source
`VSENS5` | uV DC | External source
`VSENS6` | uV DC | External source
`VSB` | uV DC | VSB
`VDD` | uV DC | VDD
`VBAT` | uV DC | VBAT
`AVDD` | uV DC | AVDD
`TS1` | uV DC | Thermistor
`TS2` | uV DC | Thermistor
`TS3` | uV DC | Thermistor

# HISTORY

The `nsclpcsio` driver first appeared in NetBSD 2.0, OpenBSD support was added in OpenBSD 3.5.

# AUTHORS

The `nsclpcsio` driver was written by Matthias Drochner <drochner@netbsd.org> for NetBSD and then ported to OpenBSD 3.5 by Markus Friedl <markus@openbsd.org>. GPIO support was added in OpenBSD 3.6 by Alexander Yurchenko <grange@openbsd.org>.
