(2) Using external trigger pulse output mode
How to change the PWM waveform in the external trigger pulse output mode is described below.
(a) Changing the PWM waveform while the counter is incrementing
Note The output from the TOPn0 pin can also be used as the input to the TIPn0 pin. When using the
Remark
To change the PWM waveform while the counter is incrementing, write to the TPnCCR1 register after
changing the waveform setting. When rewriting the TPnCCRa register after writing to the TPnCCR1
register, do so after the INTTPnCC0 signal has been detected.
