RU_nCONFIGRU_DOUT

The remote system upgrade circuitry does the following functions:

• Tracks the current state of configuration

• Monitors all reconfiguration sources

• Provides access to set up the application configuration image

• Returns the device to fallback configuration if an error occurs

• Provides access to the information on the failed application configuration image
