Hi, I'm using Atmel's 8051 AT89C51RE2 for a microcontroller application

Do I need to provide pull up resistors if I'm using port 0, or is it only for specific type of applications?
Can I continue using port 0 like any other port after providing pullup resistors to each pin?
 

NYou have to give pull-up resistors whenever you are using port 0.
You can only use it after that. If no pull up resistors given, it wont work

Can I use it like any other port after connecting resistors?
 

I am using port pins (2.0 to 2.7) as output lines . is it required to connect pull up resistors along these lines ?
