8. Initial Output in Complementary PWM Mode:
Negative phase
Positive phase
In complementary PWM mode, the initial output is determined by the setting of bits OLSN and
OLSP in the timer output control register (TOCR).
This initial output is the PWM pulse non-active level, and is output from when complementary
PWM mode is set with the timer mode register (TMDR) until TCNT_4 exceeds the value set in
the dead time register (TDDR). Figure 11.38 shows an example of the initial output in
complementary PWM mode.
An example of the waveform when the initial PWM duty value is smaller than the TDDR
value is shown in figure 11.39.
