• Examples of Waveform Output Operation
Figure 12.10 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 matches the pin level, the pin level does not change.
Figure 12.11 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.
