DRV8302: DRV8302 to be used with two phase motor

Part Number: DRV8302

Can I use DRV8302 with two phase motor - or there exists some other more appropriate part for usewith two phase brush motor?

I started drawing schematic - and then I wanted to make sure if there will be no problem if I do not use third half bridge.

In that case is it ok to leave lines hanging in air or should I tie them to GND?

Also if I use M_PWM to 3.3V (without need of INL lines), should I tie thouse to GND or is it ok to leave them float?
