    well, if you are already "controlling" the servo one way it should not be hard to change the timing to move it the other way, assuming you are talking about RC Servos, since you did not provide any motor specs or circuit schematics or even code for that matter so people could easily understand what it is you are talking about.....

    void main()
    {
    int x;
    trisb=0;
    trisd=0;
    portb=0;
    portd=0;

    for(x=0;x<4;x++)
    {
    PORTB.F7 = 1;
    Delay_us(1000);//1ms Delay
    PORTB.F7 = 0;

    Delay_us(1000);

    }
    }

    i used portb pin 7 as output for signal wire of servo motor
    this loop move motor on one direction
    i use servo motor sys s3006
