Unused pins on microcontroller
Hi!<p>I'm using an 8051 for a communication board but I am not using all the port lines. Some lines are open-collector types and others have internal pull-ups.<p>Do I need to connect all of those unused pins to a pull-down resistor? The board will be operating in a very noisy environment.<p>Thanks!
