# NAME

`gscpcib` —
National Semiconductor Geode SC1100 PCI-ISA bridge with GPIO

# SYNOPSIS

`gscpcib* at pci?`
`isa* at gscpcib?`
`gpio* at gscpcib?`

# DESCRIPTION

The `gscpcib` driver provides support for the National Semiconductor Geode SC1100 System-on-Chip PCI-ISA bridge. This device is a PCI-ISA bridge, but with some additional sub-devices. Besides the core pcib(4) functionality, the `gscpcib` driver provides support for the GPIO interface of this device.

The device has 64 I/O pins which can be accessed through the gpio(4) framework. The gpioctl(8) program provides a convenient way to manipulate these pins from userland.
