    BUTTON1 and BUTTON2 for external interrupt for xmc4500 Relax Kit

    Hi,
    I need two external interrupt in my project and want to use BUTTON1 (P1.14) and BUTTON2 (P1.15) on xmc4500 Relax Kit. I added PIN_INTERRUPT App to Dave CE 4 project. When I try to Manual Pin Allocator for it I see only BUTTON2 in the list. There is not BUTTON1. I checked user manual of xmc4500 and both pin (P1.14 and P1.15) has same Pad Type.
    Thank you for your help.

    Best regards,

    Adem

    Hi,

    Only BUTTON2 pin (P1.15) is an input to one of the ERUs. For BUTTON1 (P1.14) you need to poll the state of the pin in SW.
