NSCLPCSIO(4)

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).
