+ * The Kona PWM has some unusual characteristics.  Here are the main points.
+ *
+ * 1) There is no disable bit and the hardware docs advise programming a zero
+ *    duty to achieve output equivalent to that of a normal disable operation.
+ *
+ * 2) Changes to prescale, duty, period, and polarity do not take effect until
+ *    a subsequent rising edge of the trigger bit.
+ *
+ * 3) If the smooth bit and trigger bit are both low, the output is a constant
+ *    high signal.  Otherwise, the earlier waveform continues to be output.
+ *
+ * 4) If the smooth bit is set on the rising edge of the trigger bit, output
+ *    will transition to the new settings on a period boundary (which could be
+ *    seconds away).  If the smooth bit is clear, new settings will be applied
+ *    as soon as possible (the hardware always has a 400ns delay).
+ *
+ * 5) When the external clock that feeds the PWM is disabled, output is pegged
+ *    high or low depending on its state at that exact instant.
