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 SuperHTM
Family E10A-USB Emulator User’s Manual.

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.
