ADP5589 pull up resistor

Hello

ADP5589 IO expander has  the pull-up resistors of 100Kohm and 300Kohm.

Though I have not used  the big value pull up resistor as 300Kohm, 

  is this pull up resistor for low current consumption ?

I think that user selects the pull up resitor based on current consumption ( and noise, time constant ).

Is my understanding correct ?

Please let me know your advice.

Regars,

Terumasa
