Reverse MCU STM8S005C6T6 Flash Memory Code and readout embedded firmware from microprocessor stm8s005c6 memory, crack microcontroller stm8s005c6 fuse bit and remove its protective over the flash memory;
This divides the program memory into two areas:
Main program memory: up to 8 Kbyte minus UBC
User-specific boot code (UBC): Configurable up to 8 Kbyte
The UBC area remains write-protected during in-application programming. This means that the MASS keys do not unlock the UBC area when break stm8s103f3 micro cpu flash memory. 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.
The read-out protection blocks reading and writing the Flash program memory and data EEPROM memory in ICP mode (and debug mode) which can be disable by breaking stm8s105 protective memory fuse bit.
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.
