RS08 PWM free running, or software poll required?

Hi, I have been trying to figure out from the datasheets, but have not yet been able to see if the RS08 (KA8) can handle the pwm generation on it's own after setup.  I am using C from code warrior, but is that software interrupt polling loop required to clear interrupt bits and actually run the PWM based on polling of those bits, or can it run on it's own in hardware.  I know there are no hardware interrupt vectors, but is there hardware there to toggle actually and do the PWM without software setting and clearing bits in that interrupt poll loop?
I see for timer demos that loop is actually required to handle most tasks.  If it can do the pwm itself, are there other things that also are done without interrupt bit polling?

Thankyou for clarification.
Steve
