Hey guys,
  This is probably the 5th post I've written on this stuff but I have been having a lot of issues with my A/D conversion on my board. I got most of the code from AN3266 and that took a while to fix and debug and when i finally hooked it up to my board and ran the code, the "device is reset." During the "configuration of the system" code, I am enabling the SOPT and COP with the code
 
MOV #((SOPT) >> 6 ) & $FF,PAGESEL
MOV #(mSOPT_COPE | mSOPT_COPT | mSOPT_STOPE), (((SOPT) & $3F) + $C0)
When I have this code in the program the device gets reset but when I take it out the code can run all the way until I get to a wait statement. Does anyone have any ideas to why this would have happened? Thanks
