Question about 3/~5 output select pin of a boost IC?
The extract of the table in your question describes two pins. One is the shutdown pin and the other is the output voltage select pin (pin 2). Read the data sheet and look at the pin out and all will become clear. Connect pin 2 to the output to select 3.3 volts.

It seems that you should use a 1 Mohm resistor in series with the pin when connecting to the output.
