Upon reset, the pins are initialized as high impedence inputs. However, I have read that floating inputs are not a good thing to have in a system (Especially if it is in strong electric and magnetic fields). They aren't floating, they are pulled high by a weak internal active pull-up. And if you don't connect anything to these pins, then they aren't susceptible against noise and interference. Kai, I thought the LPC series had weird I/O structures compared to normal. Is this correct for this variant ? Steve |
