   This sets the reduced power level to apply after the <tt>timeLimit</tt>
   interval expires, as a PWM level from 0 (completely off) to 255 (100% duty
   cycle).  If the underlying hardware port is a simple digital on/off port
   (without any PWM control), this should always be set to 0, since digital
   ports aren't capable of reduced power levels, and treat any non-zero
   DOF level as simply "on".
