How can i protect a program from write/erase?

Peclare Mambe

Hi!
For a few months i use uVisoin(RealView compiler) from Keil to program the ARM LPC2138 mikrocontroller.I use also the IAP-programing and i don't want to erase or write the main program.
How can i do it?

Thanks for any answer.

Best regards

    Hi!
    I have checked the LPC213x user manual and i discover that there is one feature "code read protection" for code protection. But the fact is that only ISP commands are affected by this code and IAP commands are not.
    What i want to use is IAP commands.

    May be someboby can help me to find out the solution.

    Thank you
