(c) Conflict between trigger detection and match with CCR1 buffer register
External trigger input
CCR1 buffer register
INTTPmCC1 signal
TOPm1 pin output
If the trigger is detected immediately after the INTTPmCC1 signal is generated, the 16-bit counter is
immediately cleared to 0000H, the output signal of the TOPm1 pin is asserted, and the counter continues
counting. Consequently, the inactive period of the PWM waveform is shortened.
Remark
If the trigger is detected immediately before the INTTPmCC1 signal is generated, the INTTPmCC1 signal
is not generated, and the 16-bit counter is cleared to 0000H and continues counting. The output signal of
the TOPm1 pin remains active. Consequently, the active period of the PWM waveform is extended.
