Example S32K118 FTM PWM DMA S32DS 2.2

********************************************************************************
* Detailed Description:
*
* Example shows possible setting for PWM duty cycle update using DMA.
* FTM0 ch0 is set to Edge aligned mode with 20KHz period.
* Initialization trigger is routed back to HW trigger 1 using TRGMUX, so this HW
* trigger can be used for CnV synchronization.
* DMA on FTM0 ch0 is enabled (on ch0 CHF flag) and DMA ch0 configured to update C0V
* from duty cycle variable.
* NOte CHF is not set for 0% and 100% duty cycle, thus no DMA trigger is generated.
*
* Green LED is dimming as duty is changing.
