I'm certainly not going to reply to the message and quote the original!
Thanks very much for this and for helping in the past too.  The information
is really useful.  The pseudo random system you sent me earlier is also
working with only one modification - as the device will be reset quite often
the timer value is used as a seed which is called checking the POR bit
(resets in the product are POR) so seeding only happens once.  This gives
great results.

Thanks again

Tim
