(c) Conflict between trigger detection and match with CCRk buffer register
If the trigger is detected immediately after the INTTABnCCk signal is generated, the 16-bit counter is
immediately cleared to 0000H, the output signal of the TOABnk 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 INTTABnCCk signal is generated, the INTTABnCCk signal is
not generated, and the 16-bit counter is cleared to 0000H and continues counting. The output signal of the
TOABnk pin remains active. Consequently, the active period of the PWM waveform is extended.
