(c) Conflict between trigger detection and match with CCR1 buffer register
External trigger input
CCR1 buffer register
INTTAmCC1 signal
TOAm1 pin output
If the trigger is detected immediately after the INTTAmCC1 signal is generated, the 16-bit counter is
immediately cleared to 0000H, the output signal of the TOAm1 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 INTTAmCC1 signal is generated, the INTTAmCC1 signal is
not generated, and the 16-bit counter is cleared to 0000H and continues counting. The output signal of the
TOAm1 pin remains active. Consequently, the active period of the PWM waveform is extended.
