I suppose this is for the Philips Apps. OK all pins except a/d are 5V tolerant. What level (in the high state) will I get on a pin configured as an output if I have a pullup to 5V, and what current will it draw. Sorry to harp on, but I need to know what voltage level I can generate for my peripheral device, and what size of pull-up I can use.
