Hi @DarrenZhang1,
There is no separate documentation for individual S32K varients.
You can set the period of the PWM signal (either in Hz or Ticks) in Process Expert (S32DS v2.2) or in the Configuration tool (S32DS v3.4) of the ftm_pwm_s32k116 SDK example.
Processor expert:


The resolution of the PWM depends on the selected FTM peripheral clock and FTM clock source prescaler.

Daniel
