Figure 10.20 illustrates 0 output/1 output. In the example, TCNT is a free-running counter, 0 is
output upon compare match A and 1 is output upon compare match B. When the pin level
matches the set level, the pin level does not change.
Figure 10.21 shows an example of toggle output. In the figure, the TCNT operates as a
periodic counter cleared by GRB compare match with toggle output at both compare match A
and compare match B.
