    Extern Interrupt - XMC4300 Relax Board


    I´m trying to receive an extern interrupt.
    I used Dave APPs(- EventDedector ; EventGenerator; NVIC; DIGITAL IO)

    I never get into the service routine... I used example : XMC4500_RelaxKit_ERU_ISR

    Its not working on XMC4300 Board with button 2 but i changed it to a other Pin.

    Im using a jumper wire (3,3V - Pin0.6) but without getting in InterruptService Routine....

    Someone have experience with that case ????? Click image for larger version

    Have a look at the Usage section of the EVENT_GENERATOR APP documentation.
    You should be using, Generate service request = Independent of pattern detection
    1. In this mode, each occurring trigger event leads to a service request.
    2.The Pattern Match Output Signal can be used independently from the Trigger Output Signal for gating purposes of other peripherals.
    3. Gating Output Signal is always enabled and Gated Trigger Output Signal becomes activated with each activation of Trigger Output Signal

    Alternatively you can use the PIN_INTERRUPT APP.
