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.
