STM8S007C8
The size of the UBC is programmable through the UBC option byte
of 1 page (512 bytes) by programming the UBC option byte in ICP mode.
This divides the program memory into two areas:
●
●
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.
Figure 2.
Read-out protection (ROP)
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.
