Keisuke,
I checked the FTM chapter to find PWM output stop and could not find it. Could you please clarify which register exactly you are referring?
For example, I checked: FTM Software Output Control (FTMx_SWOCTRL) this registers allows output control from SW.
There are two bits:
- Channel n Software Output Control Value: The first allows you to select between Low and High, which I think is what you are asking
- Channel n Software Output Control Enable: Enables Software to override control of the pin.
Please let me know if this answers your question or if not, provide more details about "PWM output stop from software" in the manual.
Ioseph
