Figure 10.19 Procedure for Selecting Compare Match Waveform Output Mode
• Waveform output operation
Figure 10.20 illustrates 0 output/1 output. In the example, TCNT is a free-running counter, 0 is
output upon compare match A, and 1 is output upon compare match B. When the pin level
matches the set level, the pin level does not change.
Figure 10.21 shows an example of toggle output. In the figure, TCNT operates as a periodic
counter cleared by GRB compare match with toggle output at both compare match A and
compare match B.
