DRV8840: DRV8840PWP Current Control

Hello

I want to use DRV8840PWP on my project. However i do not want to use Current set inputs pins of DRV8840PWP. ( I0-I1-I2-I3-I4 / 23-24-25-26-27 ). 

I will not use current regulation. So i tied ISENSE pin to GND and VREF pin to V3P3. 

But what will i do about Current set inputs pins of DRV8840PWP. ( I0-I1-I2-I3-I4 / 23-24-25-26-27 ) ? Can i leave HiZ these pins?
