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