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 block of the memory. Each option
byte has to be stored twice, for redundancy, in a regular form (OPTx) and a complemented
one (NOPTx), except for the ROP (read-out protection) option byte and option bytes 8 to 16.
Option bytes can be modified in ICP mode (via SWIM) by accessing the EEPROM address
shown in Table 31: Option bytes below.
Option bytes can also be modified ‘on the fly’ by the application in IAP mode, except the
ROP and UBC options that can only be toggled in ICP mode (via SWIM).
Refer to the STM8 Flash programming manual (PM0047) and STM8 SWIM communication
protocol and debug module user manual (UM0470) for information on SWIM programming
procedures.
