TPS1663: General Queries

Part Number: TPS1663

Tool/software:

Hi 

I have below questions on TPS16632.

1. If mode pin is grounded, will the device be working on auto retry mode during a output direct short to ground?

2. Should i keep the SHDN pin grounded or floating (i can see SHDN is internally pulled up to 2.7V) if i am using the device on auto retry mode (Mode pin grounded).

3. why there is few NC pins (3,4,24,15) kept open, and some are connected to this ground (19,20,21,22,23) in Evaluation board schematics? (attached below)

4. why 24th NC pin is named as VIN2?
