VM

It's better for VM pin groups of 9,10 and 21,22 to short-circuit on the

PCB pattern. If cannot, check into transitional characteristics of total

application circuit including two motors. Through low impedance

materials, the possibility of causing some unexpected malfunctions

is incontrovertible.
