Be careful when attaching the adapter because incorrect insertion can cause fatal

damage to the MCU.

4.3 Setting Switches

The setting of JP1 switch is prepared for MCUs with their ROM area expanded in the future. Use this

setting for the current MCUs. Figure 4.2 shows the factory-setting of JP1 switch.
