Section 10 16-Bit Integrated Timer Pulse Unit (ITU)
At the point where the up-count/down-count changes in complementary PWM mode, TCNT3 and
TCNT4 will overshoot and undershoot, respectively. When this occurs, the setting conditions for
the IMFA bit of channel 3 and the overflow flag (OVF) of channel 4 are different from usual.
Transfer conditions for the buffer also differ. The timing is as shown in figures 10.36 and 10.37.
