These schemes support the remote system upgrade feature. Remote update mode is supported when using remote
system upgrade feature. You can enable or disable remote update mode with an option setting in the Quartus II
software. For more information about the remote system upgrade feature, refer to the Remote System Upgrade with
Cyclone III Devices chapter in the Cyclone III Device Handbook.
These schemes support data decompression.
Configuration voltage standard applied to V
You must follow specific requirements when interfacing Cyclone III devices with 2.5V/3.0V/3.3V configuration
voltage standards. For information on the requirements, refer to

Single Device AS Configuration
The four-pin interface of serial configuration devices consists of a serial
clock input (DCLK), serial data output (DATA), AS data input (ASDI), and
an active-low chip select (nCS). This four-pin interface connects to
Cyclone III device pins, as shown in
The Cyclone III decompression, and remote system upgrade
features are available when configuring your Cyclone III device
using AS configuration scheme.
