10.4.5 Reset-Synchronized PWM Mode
In reset-synchronized PWM mode channels 3 and 4 are combined to produce three pairs of
complementary PWM waveforms, all having one waveform transition point in common.
When reset-synchronized PWM mode is selected TIOCA3, TIOCB3, TIOCA4, TOCXA4,
TIOCB4, and TOCXB4 automatically become PWM output pins, and TCNT3 functions as an up-
counter.
Table 10-5 lists the PWM output pins. Table 10-6 summarizes the register settings.
