application configuration, the device reloads the default factory

Figure 12–3. Remote Configuration Mode
Local Configuration Mode
Local configuration mode—a simplified version of remote configuration
mode—is suitable for systems that load an application immediately upon
power-up. In this mode you can only use one application configuration,
which you can update either remotely or locally.
In local configuration mode, upon power-up, or when nCONFIG is
asserted, the Stratix or Stratix GX device loads the application
configuration immediately. Factory configuration loads only if an error
occurs during the application configuration’s user mode. If you use an
enhanced configuration device, page address 001 is the location for the
application configuration data, and page address 000 is the location for
the factory configuration data.
If the configuration data at page address 001 does not load correctly due
to cyclic redundancy code (CRC) failure, or it times-out of the enhanced
configuration device, or the external processor times-out, then the factory
configuration located at the default page (page address 000) loads into
the Stratix or Stratix GX device.
