    Hallo,

    I´ve some problem with the UART interrupts. I try to

    reset the TX_Empty Status flag in UART SR. But I`dont

    know how to do. So the IR routine will be called again

    and again. I spent some time with this problem but

    I didn`t suceed.

    I hope somebody of you can help me.

    Thx

    Frodo.

    Thanks for your answer, but I need this interrupt when I will send the next character with uart0 the same problem happens. You must know that the interrupts handels a tx buffer until it`s empty. Afterwards it will be turned off.

    If somebody has another idea, please post.

    Regards Frodo
