Waveform Output by Compare Match: The TPU can perform 0, 1, or toggle output from the
corresponding output pin using compare match.
Figure 16.8 illustrates periodic counter operation.

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.
Set the timing for compare match
generation in TGR.
Set the CST bit in TSTR to 1 to start the
count operation.
