First Put and about 400 to 500 ohm resistor from ground to the resist pin. Theory is that it makes it hard for anything to pull it up except for the reset circuit attached. Are you talking about additional pull-down resistor on RESET pin? This will ruin the RC time constant. Alternatively if you are recommending a low value for reset resistor, you will need a rather big capacitor which will make the situation worse in brownouts/power dips. |
