Examples of waveform output operation: Figure 11.10 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 11.11 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.
