5.3 Connection Diagram
Figures 5.4 shows a connection diagram of the M306NKT-EPB. This connection diagram mainly shows the interface
section. The circuits not connected to the user system such as the emulator's control system are omitted. The signals not
shown in Figure 5.4 connect the evaluation MCU and the user system directly. Tables 5.5 and 5.6 show IC electric
characteristics of this product for reference purposes.
