(l) Toggle Output Synchronized with PWM Period
In complementary PWM mode, toggle output from the PWM output pin in synchronization with the PWM period can be
enabled by setting the PSYE bit in the TOCR1A register to 1. An example of a toggle output waveform is shown in
Figure 19.61 .
This output is toggled by a compare match between MTU3.TCNT and MTU3.TGRAand a compare match between
MTU4.TCNT and 0000h.
pin is assigned for this toggle output. The initial output is high-level output.
