13.4.6
Three normal- and counter-phase PWM waveforms are output by combining channels 0 and 1 that
one of changing points of waveforms will be common.
In reset synchronous PWM mode, the FTIOB0 to FTIOD0 and FTIOA1 to FTIOD1 pins become
PWM-output pins automatically. TCNT_0 performs an increment operation. Tables 13.4 and
13.5 show the PWM-output pins used and the register settings, respectively.
Figure 13.26 shows the example of reset synchronous PWM mode setting procedure.
