pwm generation in S32K144

[harish_073024_]

Hello team

we are using S32k144 uC in our designs. we currently preparing schematics. we need some clarification in uC ADC and FTM module. 

1. we are planning to generate the PWM 16khz with 75% duty cycle using FTM modules. But we need this PWM signal when the ADC pin detects 4V.

is it possible in this uC? if it is possible can tell me how to configure this one inside the uC??

thank for clarification.

we are using for generating the PWM using pin 39 FTM0_CH7 and pin 48 FTM3_CH0 (64 pin package).

1.FTM0_CH7 channel PWM is complementary type, is it possible to invert the output signal from this pin??

2.what is default FTM signals outputs, when there is PWM generation?

3.what is the difference between FTMx_CHx vs FTMx_FLTx??

Hi,

Thank you so much for your interest in our products and for using our community.

The FTM hardware trigger source can be from many other modules via TRGMUX, like LPIT,
Low Power Timer, CMP, etc.

In your case, what you need to do is a configuration of CMP->TRGMUX->FTM.

Hope it helps you.

Have a nice day!
