Dedicated Remote System Upgrade Circuitry
Cyclone III Device Handbook, Volume 1
This section explains the implementation of the Cyclone III device family remote
system upgrade dedicated circuitry. The remote system upgrade circuitry is
implemented in hard logic. This dedicated circuitry interfaces to the user-defined
factory application configurations implemented in the Cyclone III device family logic
array to provide the complete remote configuration solution. The remote system
upgrade circuitry contains the remote system upgrade registers, a watchdog timer,
and state machines that control those components.
