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.

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.
