Norm, Understood. Regardless PWM is used to fire the fets. It just may not be from the R2LC algorithm. I think part of the other reason the later motor drivers have serial data directly is they take command from the R2LC wrt changing modes, speed steps, turning on and off cruise, etc...

If I remember correctly I mentioned in a post that K-line did not use the 4 pin connection, and Jon Z chimed in about it being a disadvantage. Implied he was still using the phase information from the R2LC. Must admit a little over my head since I don't have the background into this level of detail wrt motor control and programming. G
