CHAPTER 4 HOW TO USE MINICUBE2 WITH 78K0 MICROCONTROLLER

User’s Manual U18371EJ1V0UM

4.1 Target System Design

This section describes the target system circuit design required for on-chip debugging and flash programming.

Figure 4-1 and Figure 4-2 present overviews of the MINICUBE2 communication interface. For communication

between MINICUBE2 and the target system, communication circuits must be mounted on the target system, as

shown on the left side of the figure. Refer to this section to design circuits appropriately.
