DRV8320: 1x PWM Mode - Brakes on

Part Number:DRV8320

Hello,

I am trying to use the  DRV8320 in 1x PWM mode by leaving the MODE pin floating. However the device only turns on all the low side gates when I adjust the PWM signal from my Arduino on the INHA pin. I realize there is a "brake mode" but I tied the INLC pin high (5V) which should turn off the brakes? What am I doing wrong? I currently have the hall sensors directly connected to the INLA, INHB, and INLB pins but nothing happens. 

Thanks!
