How to use different frequencies on FTM channels of same FTM instance with S32K144 MCU

[gkunalupta]

i am using S32K144 MCU and using FTM peripheral instance 0.

I want to generate different frequencies on FTM0_CH0 and FTM0CH1.

But what i observed, if i change frequency/period of one channel by API: Ftm_Pwm_Ip_UpdatePwmPeriodAndDuty(FTM_INSTANCE_0, channel0, 35000, 12000, TRUE );

then frequency of other channel also gets changed.

I get it that MOD register for all channels is same. Thus changing MOD value for changing the frequency will change the period of whole FTM instance.

But what if i want to have different frequencies on channels of same FTM instance.

How can i achieve that?

Hi@gkunalupta

But what if i want to have different frequencies on channels of same FTM instance.

No, this can not be done in same FTM instance.
