Hi,

 

I'm using FTM3 on channel 0 to generate PWM signal. Processor expert was use to setup the timer. It works ok.

 

Now I want to change FTM3_C0V register in my app. Changing value of this register does not change the puls width.

 

I noticed that such action works:

 

FTM3_SC &= ~(1<<3);
FTM3_C0V = value
FTM3_SC |= (1<<3);

Do I really need to stop the timer to chanche C0V value?

 

Regards.
