yes the motor is driven by TB62217AFG. Its an unusual motor controller and I cannot figure out where the direction and speed bits are coming to on this chip. Probably its driven by serial input. I have uploaded its datasheet here

I will be thankful if someone could give me an idea of how this chip is being driven (so I will be able to take speed and direction data from it) or some circuit to detect the direction of motor rotation.
thanks
