TPS3703-Q1: Is LATCH mode only available when CT pin is connected to GND

Part Number: TPS3703-Q1

Hi Expert,

I have some questions about TPS3703-Q1 as below. Could you please help to clear? 

  1. Is LATCH mode only available when CT pin is connected to GND? For CT pin connected to VCC or cap, it is not available, right?
  2. Is internal sense resistance pulled down to GND? 
  3. How much will the tolerance of the resistor divider affect accuracy? How to calculate the inaccuracy? It would be the best if you can provide an example. Thanks 

Thanks a lot for your help!

BR,
