[Notes] Renesas Emulator and Flash Memory Programmer Products with a USB Interface Notice Regarding Changes to Windows Driver Policy (PDF | English, 日本語)
USB driver for countermeasures (For E2, E2Lite, and IE850A only)
The IE850A is equipped with a rich variety of debugging functions, such as events, tracing, and time measurement. This full spec emulator features 9 GB of memory for storing histories of program execution, enabling the saving and checking of histories of program execution over longer periods.
Features
- Collect long-term program execution histories
The emulator has 9 GB of memory for collecting histories of program execution, such as branches and data access. The emulator handles the memory as a set of trace frames, each with a capacity of up to 1 GB. The total capacity allows the saving and checking of histories of program execution over longer periods. - Use IE850A and E2 emulator on the same user system
The IE850A emulator supports devices equipped with the Aurora trace interface, a scalable and lightweight link-layer protocol for high-speed serial communications. Having a 34-pin connector for Aurora protocol communications on the target side, the IE850A can be used to collect histories of program execution over longer periods for use in defect analysis. - An E2 emulator can also be connected to the user system by using a conversion adapter.
You can then use the E2 for standard debugging and the IE850A for debugging that requires close trace analysis. - Rich Variety of Debugging Functions
As a full-spec. emulator, the IE850 is equipped with a rich variety of debugging functions. Along with basic functions such as stepped execution, breaks and RAM monitoring, it also supports time measurement, tracing and measurement of coverage for more efficient system development. - Learn More

AI-generated Summary:
Main-core debugging enables secure development by separating secure programs running on the ICU-M core from non-secure programs on the main CPU core. It allows debugging of non-secure user programs while keeping secure information confidential. The method uses the E1/E20/E2/IE850A emulator and requires specific system configurations and authentication procedures. Key terminology includes integrated development environment, emulator debugger, host machine, target device, and user system. Manuals for the emulator provide hardware specifications, connection details, and usage notes essential for effective debugging.

AI-generated Summary:
Debugging methods focus on devices with an initially stopped CPU core and those transitioning to standby modes to optimize power consumption. Key capabilities include verifying core activation, measuring execution times for core activation and standby transitions, and restarting debugging at critical points such as core activation or MCU wake-up. Supported devices include various RH850 series MCUs. The document details environment setup, debugging configurations in CS+ and MULTI IDEs, and specific debugging techniques for different standby modes. It also covers precautions and terminology related to debugging and device operation.
