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
Figure 9.9 shows an example of the setting procedure for waveform output by compare match
Output selection
Select waveform output mode [1]
Set output timing
[2]
[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.
