(d) Conflict between trigger detection and match with TAAnCCR0 register

If the trigger is detected immediately after the INTTAAnCC0 signal is generated, the 16-bit counter is cleared to

0000H again and continues counting up. Therefore, the active period of the TOAAn1 pin is extended by the

time from generation of the INTTAAnCC0 signal to trigger detection.

Remark n = 0 to 3, 5

If the trigger is detected immediately before the INTTAAnCC0 signal is generated, the INTTAAnCC0 signal is

not generated. The 16-bit counter is cleared to 0000H, the TOAAn1 pin is asserted, and the counter continues

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