Figure 10.30 shows examples of the output of PWM waveforms with duty cycles of 0% and
100%. If the counter is cleared by compare match with GRB, and GRA is set to a higher value
than GRB, the duty cycle is 0%. If the counter is cleared by compare match with GRA, and GRB
is set to a higher value than GRA, the duty cycle is 100%.
