DRV8350: n-Fault signal of DRV8350H

Hi Team 

 Let me ask about the n-Fault signal of DRV8350H.

1). Which Faults  are valid with DRV8350H(HARDWARE) in below table? All FAULTS?

2).What does Hi-Z mean in above table?

     Does HI-Z mean that the gate output to the  FET is fixed at Low by the internal pull-down resistor and the gate output is stopped?)

best regards
