  11  * This struct is used to configure the output pulse generation of the blackfin
  12  * timer trigger. If output_enable is set to true an external trigger signal
  13  * will generated on the pin corresponding to the timer. This is useful for
  14  * converters which needs an external signal to start conversion. active_low and
  15  * duty_ns are used to configure the type of the trigger pulse. If output_enable
  16  * is set to false no external trigger pulse will be generated and active_low
  17  * and duty_ns are ignored.
