hi,everybody. I am using MC68HC11E1 expanded mode circuit but due to some hardware problem my circuit board can't work so I take the M68HC11E1 chip to be tested on bootstrap circuit board. It works well. After i rechecked all the hardware, then i try to put the chip back to expanded mode board but it can't work. So I try to use my friend's new M68HC11E1 chip that has not been used before. It works well!!! Can anyone help me to solve this problem? Thanks a lot. |
