According to datasheet EXTONx pins draw from -1uA to +1uA.
But these pins functionality can be disabled by software (using OOC wake-up register). So we might even live with them disconnected. Not sure if this makes
sense for a 3uA max. leakage current though.

Will look at those ASAP.

Yes, switching to A3 leave us a lot of room to make things more understandable. :)
