Setting the analog trip points away from 00 should stop the status change messages you mentioned when the analog inputs were set to analog mode. Turning off the Broadcast Status Chg option should have the same affect. You can also set AN2 to something positive, like using a pullup resister to +5V so that the analog value is away from the default trip points. The analog trip points are not related to reading the actual analog values.
