FAQ
Does the NuMicro™ Cortex-M0/M4 Series support the code protected for user's program code? How to unlock the LOCK bit on the User Configuration Word? Issue Date:2015-02-09
Yes, the LOCK bit is provided on the User Configuration Word to protect user's program code. When this LOCK bit is set, all of the data on the Flash memory will be read back as 0xFFFFFFFF. At this time, the "Whole Chip Erase" operation should only be performed for the target chip to unlock the LOCK bit.
