Do you wave a dead fish over the PIC during a full moon too? The default state for peripherals is well documented and can be relied on. Most (all?) peripherals that are not analog default to off, and you can ignore them unless you specifically do something to them. In general, any pin that could be analog wakes up that way, so you have to disable A/Ds and comparators if you are not using them. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
