    Depending your osc frequency (wich you should define at the top of your code) this shoud produce the freq sweep from 11 to 41KHz
    Code:
    Freq var Byte
Duration var Word

Start:
    For Freq=45 to 16 step -1
        For duration = 0 to 10000
            High PORTB.1
            PAUSEUS Freq
            LOW PORTB.1
            PAUSEUS Freq
           NEXT
         NEXT
    GOTO Start

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
