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.

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.
