When the circuit is connected as shown in figure 1.6, the switches of the emulator are set as SW2
= 1 and SW3 = 1. For details, refer to section 3.8, Setting the DIP Switches, in the SuperH

Figure 1.6 Recommended Circuit for Connection between the H-UDI Port Connector and

MPU when the Emulator is in Use (14-Pin Type)

Notes: 1. Do not use /RESETP in the emulator after the user system has been activated.

When reset signals are used for debugging, use /RESETA.

2. Fix /RESETA as high level when it is not used.

3. When the voltage level of VccQ_SR (power supply for H-UDI and AUD) is 2.85 V

and that of VccQ_MFI (power supply for /RESETA) is 1.8 V, a level-shift circuit is
required as shown in the figure.
