Toggle Output Synchronized with PWM Cycle: In complementary PWM mode, toggle output
can be performed in synchronization with the PWM carrier cycle by setting the PSYE bit to 1 in
the timer output control register (TOCR). An example of a toggle output waveform is shown in
figure 18.48.
This output is toggled by a compare-match between TCNT_3 and TGRA_3 and a compare-match
between TCNT4 and H'0000.
The output pin for this toggle output is the TIOC3A pin. The initial output is 1.
