Thanks.
 

weak pullup and strong pull up

less current goes in to the pin, I would not recomend to use them use , put one resistor at the pin will save you a lot's oh headache during debuging

Re: weak pullup and strong pull up

thanks for the reply
 

A weak pullup will hold a value on a pin while all other drivers are in tri-state, and can be over-ridden by the value of the driver, once it starts driving. A strong pullup cannot be over-ridden by the driver, and will cause contention.
