Hello.

You can program the registers directly.

1st.  Configure the Processor Expert PWM.

2on. After Processor Expert Initialitzation  "PE_low_level_init();", set this code:

FTM0_MODE |= 1<<2;           // Write Protection Disable (1)

FTM0_SC |= 1<<5;                // Center Aligned PWM  CPWMS=1

FTM0_MODE &= 1<<2;        // Write Protection Enable (0)

This code works for me on K22.

Change FTMx to used Timer.

Regards.

Hello, I have got info from developers that this component does not provide such feature and in case you need this feature please use corresponding initialization component + PDD macros.

Anyway, it would very helpful for us if you could provide more details about your project.
