BOOSTXL-DRV8301: Current sensing

Part Number:BOOSTXL-DRV8301

Hello,

I want a sensored control PMSM with BOOSTXL-DRV8301 and LAUNCHXL-F28379D. I see that it has low side current sensing system in the hardware schematic. but what about the high side current sensing? as for motor control we need to know the 3 phase current. how the high side current sensing (SH A, SH B,SH C) is done?

thanks
