[ts-7000] Re: Strange shifting variables

["Andy Mercier" <>]

Eric,

Are you using -mcpu=arm9 as part of your compiler options?

BTW, It makes a big difference that you're accessing hardware so the
answer to the question is completely different.... This may have
something to do with the TS board. As you probably now know, your
initial posting of code was completely misleading. Help us help you. ;)
