Cyclone III Device Handbook, Volume 1
When you use the AP configuration in Cyclone III devices, the Cyclone III device
loads the default factory configuration located at the following address after device
power-up in remote update mode:
boot_address[23:0] = 24'h010000 = 24'b1 0000 0000 0000 0000
You can change the default factory configuration address to any desired address using
the APFC_BOOT_ADDR JTAG instruction. The factory configuration image is stored in
non-volatile memory and is never updated or modified using remote access. This
corresponds to the default start address location 0x010000 represented in 16-bit word
addressing (or the updated address if the default address is changed) in the
supported parallel flash memory. For more information about the application of the
APFC_BOOT_ADDR JTAG instruction in AP configuration scheme, refer to
Instructions” on page
The factory configuration image is user designed and contains soft logic (Nios II
processor or state machine and the remote communication interface) to:

Figure 9–34. Transitions Between Configurations in Remote Update Mode
Process any errors based on status information from the dedicated remote system
upgrade circuitry
Communicate with the remote host and receive new application configurations
and store the new configuration data in the local non-volatile memory device
Determine which application configuration is to be loaded into the Cyclone III
device family
Enable or disable the user watchdog timer and load its time-out value (optional)
Instruct the dedicated remote system upgrade circuitry to start a reconfiguration
cycle
