concurrently configure two different APEX devices with multiple pages storing two
revisions of each design. Two configurations for the entire system requires four
configuration files (the number of devices multiplied by the number of unique system
configurations).

By selecting the Memory Map File option, the Quartus II Memory Map output file
(.map) is generated, describing the flash memory address locations. This information
is typically useful when using the external flash interface feature.
Enhanced configuration devices support an external flash interface that allows
devices external to the controller access to the enhanced configuration device’s flash
memory. You can use the flash memory to store boot or application code for
processors, or as general-purpose memory for processors and PLDs.
