Anyone have experience with the Brownout Detect feature on the LPC936 chip? I have a complete system that works fine. I decided to try out the Brownout feature. Anytime I turn on BOE bit (done thru FlashMagic) or EBO bit, my system stops. I figured out that the stoppage is because my timers stop functioning. When I turn off either of those bits (to disable Brownout), the system works normally again. I haven't prioritized any interrupts, but that shouldn't matter I wouldn't think. Anyone have anything to check?

There is a bit that either causes a reset or as an interrupt. I'm using the interrupt method. But, I haven't been able to debug it well, because my timers stop as soon as either EBO or BOE are set. Don't know why. Supply voltage is 12V, regulated down to 3.3V for the chips. Battery operated system.
