Can anyone point me towards a website or app note where they discuss how the PIC should be configured for a noisy environment to prevent the PC from jumping to a random location. What I'm looking for is a list of good practices. I'd like to know about what I should be doing with floating pins, parking EEADR, brownout reset, waiting after powerup, etc. My problem appeared to occur during turnon of the device so maybe there was a power up glitch or something like that.
