Figure 12.10 Procedure for Selecting Compare Match Waveform Output Operation
Waveform Output Operation (0 Output/1 Output): Figure 12.11 shows 0 output/1 output. In
the example, TCNT is a free-running counter, 1 is output upon compare-match A and 0 is output
upon compare-match B. When the pin level matches the set level, the pin level does not change.

Figure 12.11 Example of 0 Output/1 Output
Waveform Output Operation (Toggle Output): Figure 12.12 shows the toggle output. In the
example, the TCNT operates as a periodic counter cleared by compare-match B, with toggle
output at both compare-match A and compare-match B.
