'Aghhh Code Protection Bit Pro'
Steve: This is a good idea of placing a global copy-protect disable in
the software; much easier than changing the silicon.
However, I should point out that CUSTOMERs are often the people that
you want to protect the device from. Ie, you are a small developer
working for Honcho Technology and send hem your working prototype.
They read out your code and sever the contract. It could happen.
In this case, it is usually better to include the price of a couple
OTPs in the contract...

Several good suggestions have been offered for this problem. Here is
two cents. The cheapest thing to change is software. I would
in a programming suite of tools geared specifically at the development
environment. I would like programming software that does not allow
protection bits to be set ever. This development software would never
code protect a part. During development we could use this safe
for customer prototypes and production we could use full featured
Here is an opportunity for all the folks writing programmer software.
Make us a version that will never intentionally set the code protect
bits. I would gladly pay the cost of a few JW packages just to be
that I did not choose the wrong option. I know that programming
can occasionally inadvertantly code protect a part. However, if we
eliminate operator error, I think we can save quite a lot of chips!

Only problem is, Honcho Technology probably resides in someones garage
after paying the usual extravagant lawyer's fees, cannot afford the
'blow-and-go' sessions. (especially on the JW part)
