Wait, are we sure it's not DMA? Seems off.

IRQ is used for interrupt requests, not direct comms.

It's definitely PIO for direct communication.

Hmm, I'm not sure about that. I was thinking the success code might be stored in the object metadata instead. But I could be wrong - I'll have to double-check the documentation on that.

I'm a bit confused on this one. I know the trigger depth error can happen when a trigger calls itself, but I'm not sure what the specific reasons could be here.
