# Full Swing Oscillator; Start-up time: 16K CK + 65 ms; Crystal Osc.; slowly rising power; [CKSEL=0111 SUT=11]
You helped me out of a previous situation where I experienced 1284 problems on a bread application.
Others have not see the problem probably do to a different circuit layout, ground plane etc.
This points to my following conclusion, if several people have seen the problem and others not, there must be something borderline or on the verge of not working.
Since a slight change in layout fixes the problem, we are playing with a situation which can/could raise it's ugly head as a bug or intermittent.
I for one will always use full swing (at a small cost of power) as it totally solves the problem, besides I have enough problems laying in wait.
Thank you Coding Badly and Crossroads!
