The "xxxE10A-USB SYSTEM" you select in the [Target] tab will differ according to the target MCU.
If you select the wrong item, the target MCU will not show up in the [CPU Select] pull down menu in the [CPU Select] dialog box displayed at the time the emulator is connected.
Please refer to "MPUs and MCUs supported by the E10A-USB Emulator （esupportdevice.pdf）" and select your specific "xxxE10A-USB SYSTEM".
The "esupportdevice.pdf" is included in the "Manuals/English/E10A-USB_common" folder on the E10A-USB Emulator Software CD-ROM.
The manual is also bundled with the latest software version that can be downloaded from our webpage.
