PWM control using QN9080

I'm using the QN9080.
I'm generating PWM using SCTimer.
I want to create a function that stops and regenerates the PWM when a specific command is received.
In the example of scimer_simple_pwm, the PWM generation has been tested, but the PWM output does not stop.
I thought using the SCTIMER_StopTimer function would stop the output at zero, but I guess not.

How can I turn the PWM output on and off?

Hi,

Some material for you to refer. Send a command string through Bluetooth to control a QN908X three-phase PWM. 

The attachment is the code.

Have a great day,

Hi,

How did you test? If possible, make some screenshots about your code.

Have a great day,

Hi,

The red circle code, you needn't put it in the function. deinit should be removed.

Thank you for your answer.
So the PWM is output with the StartTimer, and the PWM is stopped with the StopTimer?
The red circle code was in that function, so it didn't stop?
