Option bytes
Option bytes contain configurations for device hardware features as well as the memory
protection of the device. They are stored in a dedicated memory block.
All option bytes can be modified in ICP mode (with SWIM) by accessing the EEPROM
address. See Table 10 for details on option byte addresses.
The option bytes can also be modified ‘on the fly’ by the application in IAP mode, except for
the ROP, UBC and PCODESIZE values which can only be taken into account when they are
modified in ICP mode (with the SWIM).
Refer to the STM8L15x Flash programming manual (PM0051) and STM8 SWIM and Debug
Manual (UM0320) for information on SWIM programming procedures.
