In complementary PWM mode, when the counter switches from up-counter to down-counter or
vice versa, TCNT_0 and TCNT_1 overshoots or undershoots, respectively. In this case, the
conditions to set the IMFA flag in channel 0 and the UDF flag in channel 1 differ from usual
settings. Also, the transfer conditions in buffer operation differ from usual settings. Such timings
are shown in figures 13.33 and 13.34.
