This is interesting, but almost expected. As far as I understand it,
the DMA from the BSP can only transfer into the API RAM. So unless that
portion of API ram is reused, the values inevitably still have to be
there.

It is normal for such code to be hand-crafted DSP assembly, so I'm not
surprised you won't see fixed calling conventions like a compiler would
generate (or a mixed C / assembly project would require).
