10. Complementary PWM Mode 0% and 100% Duty Output
11. Toggle Output Synchronized with PWM Cycle
Toggle output
In complementary PWM mode, 0% and 100% duty cycles can be output as required. Figures
10.43 to 10.47 show output examples.
100% duty output is performed when the data register value is set to H'0000. The waveform in
this case has a positive phase with a 100% on-state. 0% duty output is performed when the data
register value is set to the same value as TGRA_3. The waveform in this case has a positive
phase with a 100% off-state.
On and off compare-matches occur simultaneously, but if a turn-on compare-match and turn-
off compare-match for the same phase occur simultaneously, both compare-matches are
ignored and the waveform does not change.
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 10.48.
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.
