This is a general question and in particular to pic, internal to micro controllers there are pull up, pull down, weak pull up, weak pull down registers for enabling and disabling. I never touch this registers in general. How important these registers. Can someone please explain in case if i enable weak pull up or pull down. What actually happens inside the controller?
