Hi Dan,
I'm confused about this, does the Go signal go to "0" after each transfer such that I have to toggle it ba...

Yes, you need to set the go bit so the dispatcher knows that the descriptor is ready to be read.

Hi Dan,
What's parked write? Is that just writing to one address only?
Is the descriptor like an address line?
