13.4.7
Three PWM waveforms for non-overlapped normal and counter phases are output by combining
channels 0 and 1.
In complementary PWM mode, the FTIOB0 to FTIOD0 and FTIOA1 to FTIOD1 pins become
PWM-output pins automatically. TCNT_0 and TCNT_1 perform an increment or decrement
operation. Tables 13.6 and 13.7 show the output pins and register settings in complementary PWM
mode, respectively.
Figure 13.29 shows the example of complementary PWM mode setting procedure.
