I am trying to get a 18F2553 to sleep using minimal current until an external interrupt wakes it. I can't get the power consumption down below about 10 mA during sleep. The only other thing in the circuit is a DS1337 and i have disconnected itdurring sleep, but see little current change. I am a beginner at this stuff and based on a search of other posts, I think the configuration fuses are the major part of the problem. Any quick suggestions?
