(c) Conflict between trigger detection and match with TAAnCCR1 register
If the trigger is detected immediately after the INTTAAnCC1 signal is generated, the 16-bit counter is cleared to
0000H at the same time, the output signal of the TOAAn1 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 INTTAAnCC1 signal is generated, the INTTAAnCC1 signal is
not generated, and the 16-bit counter is cleared to 0000H and continues counting. The output signal of the
TOAAn1 pin remains active. Consequently, the active period of the PWM waveform is extended.
