Best way to turn PWM Output off using S08PA16 FTM

Hello,

 

What is the best way to turn off a PWM Ouput from the FTM?

I am using two PWM Outputs and need to alternate between them with only one PWM Output running at a time.

 

I tried the method below on the FTM, but it does not work when I set FTMEN to 1. (required to get correct clock divider)

 

Code example:

FTM2_C4SC = 0x28; // set channel 4 as PWM Output
FTM2_C4SC = 0x00; // set channel 4 as Input Capture

When the code starts up, the channel is in Input Capture Mode and does not switch to PWM Mode.

 

Note: On the TPM this method works fine.

 

Suggestions?

 

Thanks,
David
