    Hello,

    Apologies for the delay.

    You cannot control the same pin with multiple cores at the same time. This is considered a resource conflict because you are configuring that pin more than once.

    As for why unlocking the pin resolves the resource conflict error:

    By unlocking the pin, it changes the pin to "Any," meaning that the software will select and choose any available pin. It will not use the pin P1 since that is being used by R5FSS0-1. if you want to use a specific pin (such as for layout reasons) you must lock that pin.

    Thank you,

    Susan
