p.s. I propose Freescale insert motoroladsp@moto... into the
reply address of any posting. It sometimes happens a reply intended for
the forum is accidentally sent to me personally. I'm sure I'm not the
only one.

Hi,
I have not followed your post but I had to insert "nop"s in my code in
my
56303 used as a
I/Q demodulator. The code would not hold 90 degree phase shift. I was later
told to add
wait states which also worked. The operation was rock solid after that. I
never found the real problem but I bet it is similar to yours. I tried
different clock speeds with no change. fc

Dear Gustave,
Have you checked the errata for the derivative that you are
using? Such as it is there should be no need for a NOP
because, as you say, the processor will insert an
arithmetic stall. If you are forced to insert an additional
one I'd be tempted to say there is an errata.
Regards,
