The E10A-USB emulator is an on-chip debugging emulator which supports the development for systems using microcomputers of the SuperH RISC engine family, the H8SX family, and the H8S family. As the main body of the E10A-USB emulator is connected to the user system via the dedicated debug interface (H-UDI and AUD), you can debug in such a form close to the completed product.



See the product pages for the details of each model below.

  1. The H-UDI (User Debugging Interface) is an interface compatible with the Joint Test Action Group (JTAG) specifications.
  2. The AUD (Advanced User Debugger) trace is the large-capacity trace function that is enabled when the AUD pins are connected to the emulator. When an event that starts trace acquisition occurs, the trace information is output in realtime from the AUD pins. For more details, refer to  On-chip Debuggers Performance Property.
