How exactly does the S32K3 ADC average

Hello there smart people,

I was wondering about how exatly the S32K3xx ADC behave if I enable averaging.

Let's say for example I have averaging for 4 conversions enabled:

Does it execute multiple S&H conversion cycles after one trigger happens (figure 1), does it wait for 4 triggers to occure and write the averaged result into the register (figure 2) or does it work like a moving average filter where every following result is taken into the average of the previous result (figure 3)?

I would love to hear back from you guys about this rater specific question.

Regards,
Felix
