Figure 10.36 shows examples of waveforms with 0% and 100% duty cycles (in one phase) in
complementary PWM mode. In this example the outputs change at compare match with GRB3, so
waveforms with duty cycles of 0% or 100% can be output by setting GRB3 to a value larger than
GRA3. The duty cycle can be changed easily during operation by use of the buffer registers. For
further information see section 10.4.8, Buffering.
