Hi @Bhuvana,
The FTM_DRV_UpdatePwmChannel() function can be called in the runtime to change the duty cycle.
Refer to ftm_pwm_s32k144 SDK example for more information.
Also, the FTM module allows masking the PWM output (RM rev.14, Section 47.5.17) or control the output by SW (Section 47.5.15 Software Output Control Mode).
There are these SDK API: FTM_DRV_ControlChannelOutput(), FTM_DRV_MaskOutputChannels().
Regards,
Daniel
