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 manipu-
     lation 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

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).
