The following tables describe the 4-bit DIP switch and push-button inputs that control the pre-configured Pico
Power demo. Use them as a reference for the procedure you must follow in the next step. A switch in the raised
position of the 4-bit DIP switch indicates a logic level ‘1’ input to the LC4256ZE. Depress a switch to indicate a low
logic level ‘0’.
