DMA interrupt is a half-completion interrupt or a full-completion interrupt？

Hi，

I am using the S32K144 to debug the screen. How to determine whether a DMA interrupt is a half-completion interrupt or a full-completion interrupt? I can't find the register bit for judgment.

Looking forward to your reply, thank you！

There is no flag for that and user SW will need to determine it according DONE bit and CITER/BITER values.
