Would this prevent a possible 'floating' PIN and reduce the garbage received ?
Kind regards

I like something around 4 to 5 K, enough to handle it without too much power waste. I suppose that is a way of looking at it, as I see it, True switches the circuit to a low status and the pull up returns it to high and inverted switches it to high and pull down returns to a low idle state. Now I'm going to say this with <b>absolutely NO AUTHORITY</b>, As I picture it in my mind, the communication must switch between low and open impedance for true "and/or" high and open impedance for inverted, and the resistors make the circuit.
