(b) Examples of waveform output operation

Figure 10.6 shows an example of 0-output and 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 match, the pin level does not change.

Figure 10.7 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.
