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 row of the memory.
All option bytes can be modified only in ICP mode (with SWIM) by accessing the EEPROM
address. See
Refer to the STM8TL53 Flash programming manual (PM0212) and STM8 SWIM and debug
manual (UM0320) for information on SWIM programming procedures.
