# NAME

nsclpcsio — National Semiconductor PC87366 LPC Super I/O

# 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 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 envsys(4) API. 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 device appeared in NetBSD 2.0.

# BUGS

The chip decodes address ranges which are not obvious and cannot be controlled by the kernel configuration file (must be set up by the BIOS).
