Waveform Output by Compare Match: The TPU can perform 0, 1, or toggle output from the corresponding output pin
using compare match.
• Example of setting procedure for waveform output by compare match

[1] Select initial value 0 output or 1 output, and
compare match output value 0 output, 1 output,
or toggle output, by means of TIOR. The set
initial value is output at the TIOC pin until the
first compare match occurs.
[2] Set the timing for compare match generation in
TGR.
[3] Set the CST bit in TSTR to 1 to start the count
operation.

• Examples of waveform output operation
Figure 10-10 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 and the pin level coincide, the pin level
does not change.
