The spread spectrum limit value, together with the TOP field, defines the range for the spread spectrum counter. It is introduced
in order to achieve constant varying duty cycles on the output PWM waveforms. Refer to
The top value for the timebase counter. The effective top value of the timebase counter is defined by both the TOP and the
SPREAD fields. Refer to
Writing a zero to this bit has no effect.
Writing a one to this bit will clear the timebase counter.
This bit is always read as zero.
