Re: Problem with SHL instruction

Hello,

Well to begin with. The SHL instruction is being completely ignored
because you forgot to include it in your snippet :-). Secondly, the
shift count is masked off to 5 bits (1Fh) before the shift is done.
This means that if you were trying to shift a register by 32 bits, you
would really be shifting by zero. If you were shifting by 33 bits then
the shift count would be 1.

Hope this helps

Pete
