When the circuit is connected as shown in figure 1.3, 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
TM
Family E10A-USB Emulator User’s Manual.

Figure 1.3 Recommended Circuit for Connection between the H-UDI Port Connector and
MPU when the Emulator is in Use (36-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 or /RESETMFI.
2. Fix /RESETA and /RESETMFI as high levels when they are not used.
3. When VccQ_MFI is used at 1.8 V, the level-shift circuit in figure 1.3 is required to
adjust the signal levels.
