In the few dozen devices from various manufacturers that I've had a reason
to look at in the lab, I don't think I've ever seen one that did NOT
terminate the burst before all data was transferred (not counting commands
transferring 1 sector or less).  And I've never seen one do a UDMA Pause
either.  They all seem to terminate for flow control rather than Pause.
YMMV.
