It is usually used for writing firmware. The firmware contains several blocks of continuous registers. I think it is worth, even this only saves several numbers of control transfer. This patch could replace 3 control transfers with 1 control transfer. If you could do it with one step, why do you use 3 steps? Besides, a control transfer is a complex process. I think this could reduce the loading of both software and hardware. Best Regards, Hayes
