    Hi Hayashi-san,

    ・SO          --  output of shunt amplifier is shorted. SO acts as a constant-current source

    ・nFAULT  --  nFAULT will always indicate a fault. 

    ・RSVD     --  reserved, if shorted to GND may cause nFAULT to assert

    ・IN2         --  device may not function properly, depends on MODE selection. If MODE = 1, no impact. If MODE = Hi-Z, 1/2 bridge low side will not turn on.

    What is the impact of each ?
