  • Programming but need both ICSP pins

    Usually leave the ICSP pins alone but need them for inputs. So settled on two needed momentary switches which seems safest. Is there a preference on the resistors to be pull-up or pull-down on these inputs when using them this way? Gut is telling me pull-down.

    I would use pull down's and no less than 4.7k Ohms.
