Set the pins on the adapter board (FDM) for the user boot mode.

For example, set the output of FWx to high (1) and that of MD2 to low (0).

In this example, the FWx pin outputs 1 for selecting a mode (jumper J15 is open) and MD2 (IO0) outputs 0 for serial

communication connection.

Turn off the power and select an expanded mode with on-chip ROM enabled (mode 4) or single-chip mode (mode 7).

To select the mode, use DIP switch 6. When you have set the pins, turn on the power.
