If the trigger is detected immediately after the INTTPnCC1 signal is
generated, the 16-bit counter is immediately cleared to 0000H, the output
signal of the TOPn1 pin is asserted, and the counter continues counting.
Consequently, the inactive period of the PWM waveform is shortened.
If the trigger is detected immediately before the INTTPnCC1 signal is
generated, the INTTPnCC1 signal is not generated, and the 16-bit counter
is cleared to 0000H and continues counting. The output signal of the
TOPn1 pin remains active. Consequently, the active period of the PWM
waveform is extended.
