    PWM Trap example

    Hi All,

    I would like to have a PWM output switch on and of depending on the TRAP input into the CCU unit. I can not seem to get this to work. I would either have that my PWM just does not switch off, or does not switch on.

    Setup:
    XMC1300, DAVE 4

    What I have tried the following with APPs:
    1) Add digital input
    2) Add event detecter
    3) Add event generator
    4) PWM with CCU4

    Configuration
    1) Connect DIO -> Event detector
    2) Connect Event detector -> Event Generator
    3) Connect Event generator -> "event 2" of CCU unit
    4) CCU unit has "event 2" as "External Trap", enabled at initialization, Trap level: Active high, exit synchronization: Enable, Exit control: Auto exit
    5) PWM CCU4 is setup to start during initialization

    Expectation:
    See PWM output on predefined pin appear and go away as I trigger via the digital input.

    Any help would be appreciated, even better yet, example code.

    Regards
    Enigma
