Thanks but still far away from basics.it is application specific.
as a general rule:
100k: "i'm feeling lucky today"
10k: "a day in the office"
1k: "i'm desperate".
btw, your chip has built-in PU and PD resistors.
We don't normally calculate the values of pullup/pulldown resistors; it isn't necessary. I would suggest using some value between 5 kΩ and 50 kΩ unless there is some compelling reason to do otherwise. Usually, I use 10 kΩ.Thanks but still far away from basics.
I want to connect external pull/down resistor .
