Is the value set for the option bytes of MCU specified in the assembly source file or by an option?
The value set for the option bytes can be specified either in the assembly source file or by the linker option (-USER_OPT_BYTE or -OCDBG).
However, note that, if it is specified both in the assembly source file and by the linker option, the option takes priority.
For details, refer to the user’s manual below.
