Electronics Computer Programming Q&A

I have an EVBPlus 68HC11 trainer board. I am trying to get the A/D converter working but am running into a problem. Whenever PE0 has a voltage lower than 2.5 volts attached to it, the board freezes up. I thought that maybe the pin on the chip was fried, but I ordered a new chip and it still does it. PE1, 2, and 3 all work fine though. Now, the problem is that I need 4 A/D inputs, and for some reason PE4, 5, 6, and 7 are very unreliable and do not give accurate readings at all. Any thoughts?
