    Hi Bernie,

    While this will cause a reset (depending on what is configured for the RSTCON.SMU, default is an application reset).
    Within the RSTCON.SW is a configuration to allow you to configure a Software Reset (default is an application reset).

    To issue a software reset, you need to read the SWRSTCON register, maintain the bit values for 15..8 and additionally set the bit SWRSTREQ. When written, this will issue a reset (note: this register is EINIT protected).
    After a reset occurs, the user can observe that a SW reset occurred by querying the RSTSTAT register.

    Best regards

    Hello Bernie,

    You can find a code example project for the triggering reset and detecting the source here: Reset training code example.
    this example also comes with a tutorial, which can be found here: SCU Reset tutorial.

    If you are interested in other modules and you want to start programming for AURIX™, you can get the new Integrated Development Environment (IDE) here: AURIX™ Development Studio and get inspired by numerous other trainings from here: AURIX™ Trainings.

    If you are not familiar with Eclipse based IDE’s checkout the Getting Started guide!

    Hope it helps,
