NAME

nsclpcsioNational 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
