  • I´m working with HCS08 and I´d like to know How to protect my .S19 files avoid staffs that can copy it and sell to my competitors. Are there some device that I can protect my intelectual proprerty during production process?


  • Hello Luciano,

    There is a device secure feature that is built into 9S08 device. You can enable security by programming SEC bits in NVOPT register to a specific value. You can include this value as a constant in your firmware, or you can use SECURE command in our FLASH programmer to program these bits on a fly.

    Once device is secured, you cannot debug/unsecure it, without previously erasing all contents of its FLASH.

    Best Regards,
