External Flash Interface
The enhanced configuration devices support external FPGA or processor
access to its flash memory. The unused portions of the flash memory can
be used by the external device to store code or data. This interface can also
be used in systems that implement remote configuration capabilities.
Configuration data within a particular configuration page can be
updated via the external flash interface and the system could be
reconfigured with the new FPGA image. This interface is also useful to
store Nios boot code and/or application code.

chapter of the

.
The address, data, and control ports of the flash memory are internally
connected to the enhanced configuration device controller and to external
device pins. An external source can drive these external device pins to
access the flash memory when the flash interface is available.
This external flash interface is a shared bus interface with the
configuration controller chip. The configuration controller is the primary
bus master. Since there is no bus arbitration support, the external device
can only access the flash interface when the controller has tri-stated its
