9.3.6 PWM2 Mode Operation
PWM2 mode generates a complementary output pulse with the cycle set in the FTnP register.
The duty of the Positive/Negative phase output is set in the FTnEA register. The FTnEB register is not used.
9.3.6.1 Output Waveform in PWM2 Mode
In the repeat mode, the initial values for each of Positive phase/Negative phase outputs are "L" level, and they become
"H" level at start. The positive phase output becomes "L" level and the negative phase output becomes "H" level
depending on the duty value. In the next cycle, the positive phase output becomes "H" level and the negative phase
output becomes "L" level again. This pattern repeats until the operation is stopped.
In the one-shot mode, they automatically stops after one cycle becoming "L" level. In addition, if the dead time is
enabled, the "L" level output is maintained, from the start of counting for the positive phase output and from duty
coincidence for the negative phase output, through the dead time period.
Figure 9-12(a) shows waveforms of the positive phase/negative phase output in the repeat PMW2 mode.
Figure 9-12(b) shows waveforms of the positive phase/negative phase output in the one-shot PMW2 mode.
