3. Select the Asynchronous 1 port for the FLASH Multiplexer and
click on the Configure button to enable the connection from the
flash memory to the Asynchronous 1 port of the Flash Controller.
4. On the development board, set switches SW1 to OFF (DOWN
position) and SW0 to ON (UP position).
5. Plug a headset or a speaker into the audio output jack and listen to
music produced through the Audio DAC circuit.
This procedure connects the Asynchronous 1 Port to the Audio DAC so
that the Audio DAC Controller communicate with the flash memory
directly. In this example, the AUDIO_DAC Verilog module defines a
circuit that reads the contents of the flash memory and sends it to the
external audio port.
