Write

The Write control writes the flash memory on your board. To update the flash
memory contents, change values in the table and click Write. The application writes
the new values to flash memory and then reads the values back to guarantee that the
graphical display accurately reflects the memory contents.

corresponds to address range 0x00FE0000 - 0x00FFFFFF in the uppermost portion of
the user software memory block, as shown in
