Select MultiBoot Configuration Image

Spartan-3A/3AN FPGAs support a selectable MultiBoot configuration interface. If the
FPGA configures in one of its Master configuration modes, then the FPGA always loads
the configuration image stored at address 0 in Flash at power-up, or whenever the
PROG_B button is pressed.
Spin the rotary knob to select a new FPGA configuration image. The blue text at the bottom
of the display updates with each click of the rotary knob. For example, the application
displays "Buttons: Load Configuration x" where 'x' corresponds to the bitstream image
listed in
After selecting the desired image, press one of the four push-button switches that surround
the rotary knob. This action causes the FPGA to load the selected image from external
Flash memory.
