One thing I have noticed is that I have the board next to my computer. When my monitor screen goes black (screen saver) and I move the mouse to bring it back, it create a noise and my micro wakes up, by turning the LCD on my project on, which is supposed to happen everytime one of the Ext. INT is triggered.
Makes sense? absolutely, powering up the deflection coils of a monitor generates true havoc in the ekectromagnetic environment. I had a monitor once that briefly distorted the dispaly on any other monitor within 25 feet wwhen I turmrd it on. Erik anyhow, see what the actual cause is, trap the power down exit. |
