Reverse MCU STM8S103K3T6 Flash Memory and crack security fuse bit of microcontroller stm8s103k3, then restore embedded firmware from microprocessor stm8s103k3;

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. Except for the ROP (read-out protection) byte, each option byte has to be stored twice, in a regular form (OPTx) and a complemented one (NOPTx) for redundancy.

Option bytes can be modified in ICP mode (via SWIM) by accessing the EEPROM address shown in Table 12: Option bytes below. Option bytes can also be modified ‘on the fly’ by the application in IAP mode, except the ROP option that can only be modified in ICP mode (via SWIM) of secured mcu stm8s103f2 flash memory reading.

Refer to the STM8S Flash programming manual (PM0051) and STM8 SWIM communication protocol and debug module user manual (UM0470) for information on SWIM programming procedures.

ADC accuracy vs. negative injection current: Injecting negative current on any of the analog input pins should be avoided as this significantly reduces the accuracy of the conversion being performed on another analog It is recommended to add a Schottky diode (pin to ground) to standard analog pins which may potentially inject negative current by extracting mcu stm8l052c6 flash code. Any positive injection current within the limits specified for IINJ(PIN) and SIINJ(PIN) in Section 9.3.6 does not affect the ADC accuracy.
