Compare-Match Waveform Output Function: The MTU can output 0 level, 1 level, or toggle
output from the corresponding output pins upon compare-matches.
Procedure for selecting the compare-match waveform output operation (figure 8.9):
1. Set the TIOR to select 0 output or 1 output for the initial value, and 0 output, 1 output, or
toggle output for compare-match output. The TIOC pin will output the set initial value until the
first compare-match occurs.
2. Set a value in the TGR to select the compare-match timing.
3. Set the CST bit in the TSTR to 1 to start counting.

Figure 8.9 Procedure for Selecting Compare Match Waveform Output Operation
Waveform Output Operation (0 Output/1 Output): Figure 8.10 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.
