    Standby mode undefinied reference in documentation

    hi,
    some bits are said to be set in documentation, but are nowhere defined.

    I'm currently developing standby state on AURIX.
    documentation says how to enter standby mode ( page 8-168).
    I want to use wake-up timer as trigger to exiting standby mode .
    The documentation says to set PMSWCR0.SCRCLKSEL in order to choose active WUT clock on standby entry.

    The problem is, that there is no such field. Even when I overview PMSWCR0
    (documentation chapter 8.3.2.6) register, there is no SCRCLKSE field in it.

    The field is also missing in iLLD library.


    Question is, how can I configure WUT clock source then ?

    You didn't say which AURIX device you are using?

    You can check with Infineon but I believe this is a documentation oversight issue (meaning this bit doesn't exist for your device) as the documentation uses a family approach.

    The documentation says to set PMSWCR0.SCRCLKSEL in order to choose active WUT clock on standby entry.
    Perhaps the documentation could be clearer, my opinion it is simply stating an option for the SCR Clock by taking the literal interpretation of the bit definition "SCRCLKSEL".

    Regardless the WUT can only run from the 70KHz internal OSC and its source is not configurable.
