If the trigger is detected immediately after the INTTPnCC0 signal is

generated, the 16-bit counter is cleared to 0000H and continues counting

up. Therefore, the active period of the TOPn1 pin is extended by time from

generation of the INTTPnCC0 signal to trigger detection.

If the trigger is detected immediately before the INTTPnCC0 signal is

generated, the INTTPnCC0 signal is not generated. The 16-bit counter is

cleared to 0000H, the TOPn1 pin is asserted, and the counter continues

counting. Consequently, the inactive period of the PWM waveform is
