Clone ST STM8L151C4U6 Microcontroller Chip Flash Program and copy embedded HEXIMAL program to new MCU, the status of microcontroller stm8l151c4 will be reset by breaking stm8l151c4 protection;
The watchdog system is based on two independent timers providing maximum security to the applications. Activation of the watchdog timers is controlled by option bytes or by software. Once activated, the watchdogs cannot be disabled by the user program without performing a reset.
The window watchdog is used to detect the occurrence of a software fault, usually generated by external interferences or by unexpected logical conditions, which cause the application program to abandon its normal sequence after crack stm8s103k3 secured mcu protective system.
The window function can be used to trim the watchdog behavior to match the application perfectly.
The application software must refresh the counter before time-out and during a limited time window.
A reset is generated in two situations:
Timeout: At 16 MHz CPU clock the time-out period can be adjusted between 75 µs up to 64 ms.
Refresh out of window: The downcounter is refreshed before its value is lower than the one stored in the window register.
The independent watchdog peripheral can be used to resolve processor malfunctions due to hardware or software failures which has been widely used for unlocking stm8s103k3 secured microprocessor flash memory content.
It is clocked by the 128 kHz LSI internal RC clock source, and thus stays active even in case of a CPU clock failure
The IWDG time base spans from 60 µs to 1 s.
