L6470 step loss A (or B)

i've been using the L6470 driver successfully but have noticed that i get step loss on the a and b bridge. the data sheet indicates that when this happens the appropriate bits in the status register get set. unfortunately, the data sheet does not indicate how this is being determined (if it has i missed it and so has a search through the .pdf file).

sometimes these bits are cleared with or without an over current condition/under voltage condition.

i am interested in knowing the reason for the step loss so i can take action to prevent this.

if anyone can point me in the right direction i'd be thankful.
