TIDA-010031: TIDA-010031 Schematic clarification

Part Number: TIDA-010031
Other Parts Discussed in Thread: TPS709, DRV8320

Hello ,

Q1)SBW connection TIDA -010031 is connecting to SBW TCK and SBWTDIO .

Do we need to connect TIDA board 3.3V and GND  with MSP FET debugger ? if yes to VCC_TOOL pin or VCC _Target pin

Q2) In TIDA schematic TPS70933DBVR is used. but when we give supply of 12V input it does not generate 3.3V because Enable pin is connected to microcontroller . as per TPS70933 if En pin in floating state or less than 6.5V to be applied  it can generate 3.3V . but why in schematic but different option

I was tried the setting define in schematic for normal mode and Low stand by mode. still it is not generating the 3.3V voltage . I was applied 20V at  J4 wrt GND (J5)

please explain what is the logic

Thanks & regards
