Hmm, by looking at the 'H-Bridge Secrets' [1] article by Andras Tantos I think I got an idea what the two different modes of operation are. (The article is on DC motors, but I seams to be more or less clear what it means on the phase BLDC drivers.) But I don't see how the mode of operation makes a difference regarding my synchronisation problem. What do I miss?
