Driving negative voltages with ADU-M5230

I would like to drive -700VDC (0VDC at collector of high side igbt and -700VDC at emitter side of low side IGBT) with high side and low side IGBT configuration. I understood isolation is needed because of different ground levels, i would like to use ADU-M5230 gate driver. I would like to know the reference ground voltage for the logic terminals and the output side of the gate driver.

 

Also, Do i need bootstrap circuit in addition to this gate driver?. Can anybody provide a sample application diagram with negative voltages
