Figure 9.10 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 9.11 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.
