Configuration options in this section are separated by a prefix:

The STM32 prefix limits the effect of these options to STM32 and STSPIN32 MCUs.
The STMBLUENRG prefix limits the effect of these options to “STM-BlueNRG” MCUs.

"STM32_MemoryProtSource"

This configuration option specifies whether the configuration file should be used as the source of memory protection bit values, or if the code file should be used as the source. The options specified in the main GUI are the same ones saved in the configuration file (User-defined option). If the code file is used as the source, the protection bits must be specified at the correct address within the code file. Correct addresses can be obtained from device manuals. The GUI provides an option to inspect memory protection bits as read from the code file (From File option).

If the FILE_SOURCE value is chosen for this parameter, the only parameters in this section that will also be read are "STM32_PROT_WrEn", "STM32_USER_WrEn", "STM32_RDP_WrEn", "STM32_OEMKey1_En", "STM32_OEMKey2_En", and "STMBLUENRG_PROT_WrEn".

USER_SOURCE (0) : Protection settings from the configuration file will be used (can be user defined in GUI).
FILE_SOURCE (1) : Protection settings from code file will be used (code file must include protection bits at proper addresses). (default)
