The size of the UBC is programmable through the UBC option byte, in increments of 1 page (512 bytes) by programming the UBC option byte in ICP mode.

This divides the program memory into two areas:

  • Main program memory: Up to 128 Kbytes minus UBC
    • User-specific boot code (UBC): Configurable up to 128 Kbytes

The UBC area remains write-protected during in-application programming. This means that the MASS keys do not unlock the UBC area. It protects the memory used to store the boot program, specific code libraries, reset and interrupt vectors, the reset routine and usually the IAP and communication routines when crack stm8s903k3 microcontroller flash memory.

The read-out protection blocks reading and writing the Flash program memory and data EEPROM memory in ICP mode (and debug mode). Once the read-out protection is activated, any attempt to toggle its status triggers a global erase of the program and data memory.

Even if no protection can be considered as totally unbreakable, the feature provides a very high level of protection for a general purpose microcontroller which is not feasible for cracking stm8s207c6 mcu flash memory.
