(d) Conflict between trigger detection and match with CCR0 buffer register
If the trigger is detected immediately after the INTTPmCC0 signal is generated, the 16-bit counter is
cleared to 0000H and continues counting up. Therefore, the active period of the TOPm1 pin is extended by
time from generation of the INTTPmCC0 signal to trigger detection.
Remark
If the trigger is detected immediately before the INTTPmCC0 signal is generated, the INTTPmCC0 signal
is not generated. The 16-bit counter is cleared to 0000H, the TOPm1 pin is asserted, and the counter
continues counting. Consequently, the inactive period of the PWM waveform is shortened.
