2. Examples of waveform output operation
Figure 10.10 shows an example of 0 output/1 output. In this example TCNT has been
designated as a free-running counter, and settings have been made so that 1 is output by
compare match A, and 0 is output by compare match B. When the set level and the pin level
coincide, the pin level does not change.

Figure 10.11 shows an example of toggle output. In this example TCNT has been designated
as a periodic counter (with counter clearing performed by compare match B), and settings have
been made so that output is toggled by both compare match A and compare match B.
